What you’ll learn

What is Options Assignment?

How options assignment works, identifying option assignment , examples of option assignment, managing and mitigating assignment risks, what option assignment means for individual traders.

• Conclusion 

Dive into the realm of options trading and you’ll find a tapestry of processes and potential. “Options assignment” is one pivotal cog in this intricate machine. To a newcomer, this term might seem a tad daunting. But a step-by-step walk-through can demystify its core.

In its simplest form, options assignment means carrying out the rights specified in an option contract. Holding an option allows a trader the choice to buy or sell a particular asset, but there’s no compulsion. The moment they opt to use this right, that’s when options assignment kicks in.

Think of it this way: You’ve got a ticket (option) to a show (buy or sell an asset). You decide if and when to attend. When you make the move, that transition is the options assignment.

There are two main types of option assignments:

• Call Option Assignment : Triggered when a call option holder exercises their right. The seller of the option then steps into the spotlight, bound to sell the asset at the agreed-upon price.
• Put Option Assignment : Conversely, if a put option holder steps forward, the seller of the put takes the stage. Their role? To buy the asset at the specified rate.

To truly grasp options assignment, one must understand the dance between rights and obligations in options trading.

When a trader buys an option, they’re essentially reserving a right, a possible move. On the other hand, selling an option translates to accepting a duty if the option’s holder chooses to play their card.

Rights with Call Options: Buying a call option grants you a special privilege. You can procure the underlying asset at a set price before the option expires. If you choose to exercise this right, the one who sold you the call gets assigned. Their task? Handing over the asset at that set price.

Obligations with Put Options: Securing a put option empowers you to sell the underlying at a pre-decided rate. Should you exercise this, the put’s seller steps up, committed to buying the asset at the given rate.

Several factors steer the course of options assignment, including intrinsic value, looming expiration dates, and current market vibes. To stay ahead of these influences, many traders utilize option trade alerts for timely insights. And remember, while many options might find buyers, not all see execution. Hence, not every seller will get assigned. For traders, understanding this rhythm is vital, shaping many strategies in options trading. 

In the multifaceted world of options trading, discerning option assignment straddles the line between art and science. While no technique guarantees surefire results, several pointers and signals can wave a flag, hinting at an impending assignment.

In-the-Money Options : A robust sign of a looming assignment is the option’s stance relative to its strike price. “In-the-money” refers to an option’s moneyness , and plays a pivotal role in the behavior of option holders. Deeply in-the-money (ITM) options amplify the odds of assignment. An ITM call option, where the market price of the asset towers above the strike price, encourages the holder to exercise and swiftly offload the asset on the market. Conversely, an ITM put option, where the market price trails significantly behind the strike price, incentivizes the holder to scoop up the asset in the market and then exercise the option to vend it at the loftier strike price.

Expiration’s Shadow: The ticking clock of an expiring option raises the assignment stakes, especially if it remains ITM. Many traders make their move just before the eleventh hour to capitalize on their gains.

Dividend Dates in Focus: Call options inching toward expiry ahead of a dividend date, especially if they’re ITM, stand at an elevated assignment crosshair. Option aficionados might play their call options to pocket the dividend, which they’d bag if they possess the core shares.

Extrinsic Value’s Decline : A diminishing time or extrinsic value of an option elevates its exercise odds. When intrinsic value dominates an option’s worth, a holder might be inclined to cash in on this value.

Volume & Open Interest Dynamics : A sudden surge in trading or a dip in open interest can be telltale signs. Understanding volume’s role is crucial as such fluctuations might hint at traders either hopping in or out, suggesting possible exercises and assignments. 

Navigating the Post-Assignment Terrain

Grasping the ripple effects of option assignment is vital, highlighting the immediate responsibilities and potential paths for both the buyer and seller.

For the Option Seller:

• Call Option Assignment : For a trader who’s sold a call option, assignment means they’re on the hook to hand over the underlying shares at the strike price. If they’re short on shares, a market purchase is in order—potentially at a loss if market prices overshoot the strike.
• Put Option Assignment: Assignment on a peddled put option necessitates the trader to buy the shares at the strike price . If this price overshadows the market rate, losses loom.

For the Option Buyer:

• Call Option Play : Exercising a call lets the buyer snap up shares at the strike price. They can either nestle with them or trade them off.
• Put Option Play: Exercising a put gives the buyer the reins to sell their shares at the strike price. This play often pays off when the market rate is dwarfed by the strike, ensuring a tidy profit on the dispensed shares.

Post-assignment, all involved must be on their toes, knowing what triggers margin calls , especially if caught off-guard by the assignment. Tax implications may also hover, influenced by the trade’s nature and the tenure of the position.

Being savvy about these subtleties and gearing up for possible turns of events can drastically refine one’s journey through the options trading maze. 

Call Option Assignment Scenario

Imagine an investor purchases an Nvidia ( NVDA ) call option at a strike price of $435, hoping that the price of the stock will ascend after finding out that they may be forced to move out of some countries . The option is set to expire in a month. Soon after, not only did NVDA rebound from the news, but they reported very strong quarterly earnings, propelling the stock to $455.

Spotting the favorable trend, the investor opts to wield their right to purchase the stock at the agreed strike price of $435, despite its $455 market value. This initiates the option assignment.

The other investor, having sold the option, must now part with their NVDA shares at $435 apiece. If they’re short on stocks, they’d have to fetch them at the going rate of $455 and let them go at a deficit. The first investor, however, stands at a crossroads: retain the shares in hopes of further gains or swiftly trade them at $455, reaping a neat sum. 

Put Option Assignment Scenario

Let’s visualize an investor who speculates a dip in the share price of V.F. Corporation ( VFC ) after seeing news about an activist investor causing shares to jump almost 14% in a day . To hedge their bets, they secures a put option from another investor at a strike price of $18.50, set to lapse in a month.

Fast forward a week, let’s say VFC divulges lackluster quarterly figures, causing the stock to dive to $10. The first investor, seizing the moment, employs their put option, electing to sell their shares at the $18.50 strike price.

When the assignment bell tolls, the other investor finds himself bound to buy the shares from the first investor at the agreed $18.50, a rate that overshadows the current $10 market value. The first investor thus sidesteps the market slump, securing a favorable sale. The other investor, however, absorbs a loss, acquiring stocks at a premium to their market worth.

The realm of options trading is akin to navigating a dynamic river, demanding a sharp comprehension of the risks that lie beneath its surface. A predominant risk that traders often encounter is assignment risk. When one assumes the role of an option seller, they inherit the duty to honor the contract if the buyer opts to exercise. Grasping the gravity of this can make the difference, underscoring the necessity of adept risk management.

A savvy approach to temper assignment risk is by keeping a vigilant eye on the extrinsic value of options. Generally, options rich in extrinsic value tend to resist early assignment. This resistance emerges as the extrinsic value dwindles when the option dives deeper in-the-money, thereby tempting the holder to exercise.

Furthermore, economic currents, ranging from niche corporate updates to sweeping market tides, can be triggers for option assignments. Staying attuned to these economic ripples equips traders with the vision needed to either tweak or maintain their positions. For example, traders may opt to sidestep selling options that are deeply in-the-money, given their higher susceptibility to assignments due to their shrinking extrinsic value.

Incorporating spread tactics, like vertical spreads  or iron condors, furnishes an added shield. These strategies can dampen the risk of assignment since one part of the spread frequently balances the risk of its counterpart. Should the specter of a short option assignment hover, traders might contemplate ‘rolling out’ their stance. This move entails repurchasing the short option and subsequently selling another, possibly at a varied strike rate or a more distant expiry.

Yet, despite these protective layers, it remains pivotal for traders to brace for possible assignments. Maintaining ample liquidity, be it in capital or necessary shares, can avert unfavorable scenarios like hasty liquidations or stiff margin charges. Engaging regularly with brokers can also shed light, occasionally offering a heads-up on looming assignments.

In conclusion, the bedrock of risk management in options trading is rooted in perpetual learning. As traders hone their craft, their adeptness at forecasting and navigating assignment risks sharpens.

In the intricate world of options trading, option assignments aren’t just nuanced details; they’re pivotal moments with deep-seated implications for individual traders and the health of their portfolios. Beyond the immediate financial aftermath, assignments can reshape trading plans, risk dynamics, and the overarching path of an investor’s journey.

At its core, option assignments can transform a trader’s asset landscape. Consider a trader who’s short on a call option. If they’re assigned, they might be compelled to supply the underlying stock. This can result in a rapid stock outflow from their portfolio or, if they don’t possess the stock, birth a short stock stance. On the flip side, a trader short on a put option who faces assignment may find themselves buying the stock at the strike price, thereby dipping into their cash reserves.

These immediate shifts can generate broader portfolio ripples. An unexpected gain or shedding of stocks can jostle a trader’s asset distribution, veering it off their envisioned path. If, for instance, a trader had charted a particular stock-to-cash distribution or a meticulous diversification blueprint, an option assignment might throw a spanner in the works.

Additionally, assignments can serve as a real-world litmus test for a trader’s risk-handling prowess . A surprise assignment might spark margin calls for those not sufficiently fortified with capital. It stands as a poignant nudge about the essence of ensuring liquidity and safeguarding against the unpredictable whims of the market.

Strategically speaking, recurrent assignments might signal it’s time for traders to recalibrate. Are the options they’re offloading too submerged in-the-money? Have they factored in pivotal market shifts that might heighten early exercise odds? Such reflective moments can pave the way for refining and elevating trading methods. 

In the multifaceted world of options trading, option assignment stands out as both a potential boon and a challenge. Far from being a simple checkbox in the process, its ramifications can mold the contours of a trader’s portfolio and steer long-term tactics. The importance of comprehending and adeptly managing option assignment resonates, whether you’re dipping your toes into options for the first time or weaving through intricate trades with seasoned expertise. 

Furthermore, mastering options trading is about integrating its myriad concepts into a cohesive playbook. Whether it’s differentiating trading strategies like the iron condor from the iron butterfly strategy or delving deep into the nuances of option assignments, each component enriches the narrative of a trader’s odyssey. As markets shift and new hurdles arise, a solid grasp of foundational principles remains an invaluable asset. In this perpetual dance of learning and evolution, may your trading maneuvers always be well-informed, proactive, and adept. 

Understanding Options Assignment: FAQs

What factors influence the likelihood of an option being assigned.

Several factors come into play, including the option’s intrinsic value , the time remaining until expiration, and upcoming dividend announcements. Options that are deep in the money or nearing their expiration date are more likely to be assigned.

Are Some Option Styles More Prone to Assignment than Others?

Absolutely. When considering different option styles , it’s essential to note that American-style options can be exercised at any point before their expiration, which means they face a higher risk of early assignment. In contrast, European-style options can only be exercised at expiration.

How Do Current Market Trends Impact Assignment Risk?

Factors like market volatility, notable price shifts, and external economic happenings can amplify the chances of an option being assigned. For example, an option might be assigned before a company’s ex-dividend date if the expected dividend outweighs the weakening of theta decay .

Can Traders Reverse or Counter the Effects of an Option Assignment?

Once an option has been assigned, it’s set in stone. However, traders can maneuver within the market to balance out the implications of the assignment, such as procuring or selling the underlying asset.

Are There Any Fees Tied to Option Assignments?

Indeed, brokers usually impose a fee for both assignments and exercises. The specific fee can differ depending on the broker, making it essential for traders to understand their brokerage’s charging scheme.

Trading Options: Understanding Assignment

The options market can seem to have a language of its own. To the average investor, there are likely a number of unfamiliar terms, but for an individual with a short options position—someone who has sold call or put options—there is perhaps no term more important than " assignment "—the fulfilling of the requirements of an options contract.

Options trading carries risk and requires specific approval from an investor's brokerage firm. For information about the inherent risks and characteristics of the options market, refer to the Characteristics and Risks of Standardized Options also known as the Options Disclosure Document (ODD).

When someone buys options to open a new position ("Buy to Open"), they are buying a right —either the right to buy the underlying security at a specified price (the strike price) in the case of a call option, or the right to sell the underlying security in the case of a put option.

On the flip side, when an individual sells, or writes, an option to open a new position ("Sell to Open"), they are accepting an obligation —either an obligation to sell the underlying security at the strike price in the case of a call option or the obligation to buy that security in the case of a put option. When an individual sells options to open a new position, they are said to be "short" those options. The seller does this in exchange for receiving the option's premium from the buyer.

American-style options allow the buyer of a contract to exercise at any time during the life of the contract, whereas European-style options can be exercised only during a specified period just prior to expiration. For an investor selling American-style options, one of the risks is that the investor may be called upon at any time during the contract's term to fulfill its obligations. That is, as long as a short options position remains open, the seller may be subject to "assignment" on any day equity markets are open. 

What is assignment?

An option assignment represents the seller's obligation to fulfill the terms of the contract by either selling or buying the underlying security at the exercise price. This obligation is triggered when the buyer of an option contract exercises their right to buy or sell the underlying security.

To ensure fairness in the distribution of American-style and European-style option assignments, the Options Clearing Corporation (OCC), which is the options industry clearing house, has an established process to randomly assign exercise notices to firms with an account that has a short option position. Once a firm receives an assignment, it then assigns this notice to one of its customers who has a short option contract of the same series. This short option contract is selected from a pool of such customers, either at random or by some other procedure specific to the brokerage firm. 

How does an investor know if an option position will be assigned?

While an option seller will always have some level of uncertainty, being assigned may be a somewhat predictable event. Only about 7% of options positions are typically exercised, but that does not imply that investors can expect to be assigned on only 7% of their short positions. Investors may have some, all or none of their short positions assigned.

And while the majority of American-style options exercises (and assignments) happen on or near the contract's expiration, a long options holder can exercise their right at any time, even if the underlying security is halted for trading. Someone may exercise their options early based upon a significant price movement in the underlying security or if shares become difficult to borrow as the result of a pending corporate action such as a buyout or takeover. 

Note: European-style options can only be exercised during a specified period just prior to expiration. In U.S. markets, the majority of options on commodity and index futures are European-style, while options on stocks and exchange-traded funds (ETF) are American-style. So, while SPDR S&P 500, or SPY options, which are options tied to an ETF that tracks the S&P 500, are American-style options, S&P 500 Index options, or SPX options, which are tied to S&P 500 futures contracts, are European-style options.

What happens after an option is assigned?

An investor who is assigned on a short option position is required to meet the terms of the written option contract upon receiving notification of the assignment. In the case of a short equity call, the seller of the option must deliver stock at the strike price and in return receives cash. An investor who doesn't already own the shares will need to acquire and deliver shares in return for cash in the amount of the strike price, multiplied by 100, since each contract represents 100 shares. In the case of a short equity put, the seller of the option is required to purchase the stock at the strike price.

How might an investor's account balance fluctuate after opening a short options position?

It is normal to see an account balance fluctuate after opening a short option position. Investors who have questions or concerns or who do not understand reported trade balances and assets valuations should contact their brokerage firm immediately for an explanation. Please keep in mind that short option positions can incur substantial risk in certain situations.

For example, say XYZ stock is trading at $40 and an investor sells 10 contracts for XYZ July 50 calls at $1.00, collecting a premium of $1,000, since each contract represents 100 shares ($1.00 premium x 10 contracts x 100 shares). Consider what happens if XYZ stock increases to $60, the call is exercised by the option holder and the investor is assigned. Should the investor not own the stock, they must now acquire and deliver 1,000 shares of XYZ at a price of $50 per share. Given the current stock price of $60, the investor's short stock position would result in an unrealized loss of $9,000 (a $10,000 loss from delivering shares $10 below current stock price minus the $1,000 premium collected earlier).

Note: Even if the investor's short call position had not been assigned, the investor's account balance in this example would still be negatively affected—at least until the options expire if they are not exercised. The investor's account position would be updated to reflect the investor's unrealized loss—what they could lose if an option is exercised (and they are assigned) at the current market price. This update does not represent an actual loss (or gain) until the option is actually exercised and the investor is assigned. 

What happens if an investor opened a multi-leg strategy, but one leg is assigned?

American-style option holders have the right to exercise their options position prior to expiration regardless of whether the options are in-, at- or out-of-the-money. Investors can be assigned if any market participant holding calls or puts of the same series submits an exercise notice to their brokerage firm. When one leg is assigned, subsequent action may be required, which could include closing or adjusting the remaining position to avoid potential capital or margin implications resulting from the assignment. These actions may not be attractive and may result in a loss or a less-than-ideal gain.

If an investor's short option is assigned, the investor will be required to perform in accordance with their obligation to purchase or deliver the underlying security, regardless of the overall risk of their position when taking into account other options that may be owned as part of the overall multi-leg strategy. If the investor owns an option that serves to limit the risk of the overall spread position, it is up to the investor to exercise that option or to take other action to limit risk. 

Below are a couple of examples that underscore how important it is for every investor to understand the risks associated with potential assignment during market hours and potentially adverse price movements in afterhours trading.

Example #1: An investor is short March 50 XYZ puts and long March 55 XYZ puts. At the close of business on March expiration, XYZ is priced at $56 per share, and both puts are out of the money, which means they have no intrinsic value. However, due to an unexpected news announcement shortly after the closing bell, the price of XYZ drops to $40 in after-hours trading. This could result in an assignment of the short March 50 puts, requiring the investor to purchase shares of XYZ at $50 per share. The investor would have needed to exercise the long March 55 puts in order to realize the gain on the initial multi-leg position. If the investor did not exercise the March 55 puts, those puts may expire and the investor may be exposed to the loss on the XYZ purchase at $50, a $10 per share loss with XYZ now trading at $40 per share, without receiving the benefit of selling XYZ at $55.

Example #2: An investor is short March 50 XYZ puts and long April 50 XYZ puts. At the close of business on March expiration, XYZ is priced at $45 per share, and the investor is assigned XYZ stock at $50. The investor will now own shares of XYZ at $50, along with the April 50 XYZ puts, which may be exercised at the investor's discretion. If the investor chooses not to exercise the April 50 puts, they will be required to pay for the shares that were assigned to them on the short March 50 XYZ puts until the April 50 puts are exercised or shares are otherwise disposed of.

Note: In either example, the short put position may be assigned prior to expiration at the discretion of the option holder. Investors can check with their brokerage firm regarding their option exercise procedures and cut-off times.

What Is an Option Assignment?

Definition and Examples of Assignment

How does assignment work, what it means for individual investors.

Morsa Images / Getty Images

An option assignment represents the seller of an option’s obligation to fulfill the terms of the contract by either selling or purchasing the underlying security at the exercise price. Let’s explain what that means in more detail.

Key Takeaways

• An assignment represents the seller of an option’s obligation to fulfill the terms of the contract by either selling or purchasing the underlying security at the exercise price. 
• If you sell an option and get assigned, you have to fulfill the transaction outlined in the option.
• You can only get assigned if you sell options, not if you buy them.
• Assignment is relatively rare, with only 7% of options ultimately getting assigned.

An assignment represents the seller of an option’s obligation to fulfill the terms of the contract by either selling or purchasing the underlying security at the exercise price. Let’s explain what that means in more detail.

When you sell an option to someone, you’re selling them the right to make you engage in a future transaction. For example, if you sell someone a put option , you’re promising to buy a stock at a set price any time between when the transaction happens and the expiration date of the option.

If the holder of the option doesn’t do anything with the option by the expiration date, the option expires. However, if they decide that they want to go through with the transaction, they will exercise the option. 

If the holder of an option chooses to exercise it, the seller will receive a notification, called an assignment, letting them know that the option holder is exercising their right to complete the transaction. The seller is legally obligated to fulfill the terms of the options contract.

For example, if you sell a call option on XYZ with a strike price of $40 and the buyer chooses to exercise the option, you’ll be assigned the obligation to fulfill that contract. You’ll have to buy 100 shares of XYZ at whatever the market price is, or take the shares from your own portfolio and sell them to the option holder for $40 each.

Options traders only have to worry about assignment if they sell options contracts. Those who buy options don’t have to worry about assignment because in this case, they have the power to exercise a contract, or choose not to.

The options market is huge, in that options are traded on large exchanges and you likely do not know who you’re buying contracts from or selling them to. It’s not like you sell an option to someone you know and they send you an email if they choose to exercise the contract, rather it is an organized process.

In the U.S., the Options Clearing Corporation (OCC), which is considered the options industry clearinghouse, helps to facilitate the exchange of options contracts. It guarantees a fair process of option assignments, ensuring that the obligations in the contract are fulfilled.

When an investor chooses to exercise a contract, the OCC randomly assigns the obligation to someone who sold the option being exercised. For example, if 100 people sold XYZ calls with a strike of $40, and one of those options gets exercised, the OCC will randomly assign that obligation to one of the 100 sellers.

In general, assignments are uncommon. About 7% of options get exercised, with the remaining 93% expiring. Assignment also tends to grow more common as the expiration date nears.

If you are assigned the obligation to fulfill an options contract you sold, it means you have to accept the related loss and fulfill the contract. Usually, your broker will handle the transaction on your behalf automatically.

If you’re an individual investor, you only have to worry about assignment if you’re involved in selling options. Even then, assignments aren't incredibly common. Less than 7% of options get assigned and they tend to get assigned as the option’s expiration date gets closer.

Having an option assigned does mean that you are forced to lock in a loss on an option, which can hurt. However, if you’re truly worried about assignment, you can plan to close your position at some point before the expiration date or use options strategies that don’t involve selling options that could get exercised.

Steps in the assignment process for early exercise

• Decision to exercise Option holders may choose to exercise early when market conditions align, potentially fearing a reversal in stock prices that could erode profits, or wanting to capitalize on an upcoming dividend
• Initial notification The Options Clearing Corporation is informed upon early exercise, randomly assigning a brokerage client who is short a matching option.
• Assignment notification The short option holder is notified by their brokerage about being assigned and is now responsible for meeting the option contract's terms.
• Fulfilling the obligation Option writers must deliver the underlying asset for call options or pay for the underlying asset for put options. This is typically an automated process carried out by brokerages.

Assignment in Options Trading

Introduction articles, what is an options assignment.

In options trading , an assignment occurs when an option is exercised.   

As we know, a buyer of an option has the right but not the obligation to buy or sell an underlying asset depending on what option they have purchased. When the buyer exercises this right, the seller will be assigned and will have to deliver or take delivery of what they are contractually obliged to. For stock options, it is typically 1 , 000 shares per contract for the UK ; and 100 shares per contract in the US.   

As you can see, a buyer will never be assigned, only the seller is at risk of assignment. The buyer, however, may be auto exercised if the option expires in-the-money .

The Mechanics of Assignment

Assignment of options isn’t a random process. It’s a methodical procedure that follows specific steps, typically beginning with the option holder’s decision to exercise their option. The decision then gets routed through various intermediaries like brokers and clearing +houses before the seller is notified.

• Exercise by Holder: The holder (buyer) of the option exercises their right to buy (for Call ) or sell (for Put ).
• Random Assignment by a Clearing House: A clearing house assigns the obligation randomly among all sellers of the option.
• Fulfilment by the Writer: The writer (seller) now must fulfill the obligation to sell (for Call) or buy (for Put) the underlying asset.

Option Assignments: Calls and Puts

Call option assignments.

When a call option holder chooses to exercise their right, the seller of the call option gets assigned. In such a situation, the seller is obligated to sell the underlying asset at the strike price to the call option holder.

Put Option Assignments

Similarly, if a put option holder decides to exercise their right, the put option seller gets assigned. The seller is then obligated to buy the underlying asset at the strike price from the put option holder.

The Implications of Assignments for Options Traders

Understanding assignment in options trading is crucial as it comes with potential risks and rewards for both parties involved.

For Option Sellers

Option sellers, or ‘writers,’ face the risk of unexpected assignments. The risk of being assigned early is especially present for options that are in the money or near their expiration date. We explain the difference between American and European assignments below.

For Option Holders

For option holders, deciding when to exercise an option (potentially leading to assignment) is a strategic decision. This decision must consider factors such as the intrinsic value of the option, the time value, and the dividend payment of the underlying asset.

Can Options be assigned before expiration?

In short, Yes, but it depends on the style of options you are trading. 

American Style – Yes, this type of option can be assigned on or before expiry. 

European Style – No, this type of option can only be assigned on the expiry date as defined in the contract specifications.

Options Assignment Example

For example, an investor buys XYZ PLC 400 call when the stock is trading at 385. The stock in the coming weeks rises to 425 after some good news, the buyer then decides to exercise their right early to buy the XYZ PLC stock at 400.  

In this scenario, the call seller (writer) has been assigned and will have to deliver stock at 400 to the buyer (sell their stock at 400 when the prevailing market is 425).   

An option typically would only be assigned if it is in the money, considering factors like dividends which do play an important role in exercise/assignments.

Can an Options Assignment be Prevented?

Assignment can sometimes come as a bit of a surprise but normally you should see it coming. You can only work to prevent assignment by closing the option before expiry or before any possible risk of assignment.

Managing Risks in Options Trading

While options trading can offer high returns, it is not devoid of risks. Therefore, understanding and managing these risks is key.  

Buyers Risk: The premium paid for an option is at risk. If the option is not profitable at expiration, the premium is lost.  

Writers Risk: The writer takes on a much larger risk. If a call option is assigned, they must sell the underlying asset at the strike price, even if its market price is higher.

Options Assignment Summary

The concept of ‘assignment’ in options trading, although complex, is a cornerstone of understanding options trading. It not only clarifies the responsibilities of an options seller but also helps the traders to gauge and manage their risks more effectively. Successful trading involves not just knowing your options but also understanding your obligations.

Options assignment refers to the process by which the seller (writer) of an options contract is obligated to fulfill their contractual obligation to buy or sell the underlying asset, as specified by the terms of the options contract.

When does options assignment occur?

Options assignment can occur when the buyer of the options contract exercises their right to buy (in the case of a call option) or sell (in the case of a put option) the underlying asset before or at expiration .

How does options assignment work?

When a buyer exercises their options contract, a clearing house randomly assigns a seller who is short (has written) the same options contract to fulfill the obligations of the exercise.

What happens to the seller upon options assignment?

If assigned, the seller (writer) of the options contract is obligated to fulfill their contractual obligation by buying or selling the underlying asset at the specified price (strike price) per the terms of the options contract.

Can options be assigned before expiration?

Yes, options can be assigned at any time (depending on contract type) before expiration if the buyer chooses to exercise their right. However, it is more common for options to be assigned closer to expiration as the time value diminishes.

What factors determine options assignment?

Options assignment is determined by the buyer’s decision to exercise their options contract. They may choose to exercise if the options contract is in-the- money and it is financially advantageous for them to do so.

How can I avoid options assignment? 

As a seller (writer) of options contracts, you can avoid assignment by closing your position before expiration through a closing trade (buying back the options contract) or rolling it over to a future expiration date.

What happens if I am assigned on a short call option?

If assigned on a short call option, you are obligated to sell the underlying asset at the specified price (strike price). This means you would need to deliver the shares . To fulfill this obligation, you may need to buy the shares in the open market if you do not hold them .

What happens if I am assigned on a short put option?

If assigned on a short put option, you are obligated to buy the underlying asset at the specified price (strike price). This means you would need to purchase the shares .  

How does options assignment affect my account?

Options assignment can impact your account by requiring you to fulfill the obligations of the assigned options contract, which may involve buying or selling the underlying asset. It is important to have sufficient funds or margin available to cover these obligations.

OptionsDesk Tips & Considerations

You should always have enough funds in your account to cover any assignment risk. If you have a short call position and it is in-the-money at the time of an ex-dividend be aware of extra assignment risk here as buyer/holder of the option may look to exercise to qualify for the dividend. Assignments can happen at any time!

Automatic Exercise: What it is, How it Works, Example

Katrina Ávila Munichiello is an experienced editor, writer, fact-checker, and proofreader with more than fourteen years of experience working with print and online publications.

What Is Automatic Exercise?

Automatic exercise is a procedure implemented to protect an option holder where the Option Clearing Corporation (OCC) will automatically exercise an " in the money " option for the holder, typically at an option's expiration date and time. For ordinary listed equity options in the United States, expiration typically falls at the end of trading on the third Friday of every month.

With automatic exercise, a trader or investor who forgets about the date, or who is otherwise unable to manually instruct their broker or clearing firm to exercise their in the money options, will have the benefit of having their profitable contracts taken care of on their behalf.

How an Automatic Exercise Works

Options contracts give their holders the right, but not the obligation, to buy (for a call option) or sell (for a put option) a set amount of the underlying security at a pre-determined strike price, on or before the contract's expiration date (for an American style option. European options can only be exercised upon expiration).

Example of Automatic Exercise

Say a trader purchases the $50 strike call on XYZ shares when the stock is trading at $40. This gives the trader the right to purchase XYZ stock for $50 in the future. At expiration, if XYZ shares have risen to $42, the trader will let the calls expire worthless because there is no benefit to buying the stock for $8 higher than the current market price. However, if the price of the stock rises to $60, the trader will want to exercise his right to purchase shares at $50 in order to make an immediate $10 profit per share (minus the premium paid).

But, suppose the trader forgets that it is the third Friday of the expiration month—or does not have access to their broker because they are on vacation, or otherwise indisposed. If they fail to exercise their in the money options, they will lose the profit opportunity. Fortunately, the Options Clearing Corporation (OCC)—which is the central clearing house for all listed options traded and exchanges in the U.S.—will automatically exercise these options on his behalf.

The OCC has provisions for the automatic exercise of certain in-the-money options at expiration, a procedure also referred to as "exercise by exception." Generally, the OCC will automatically exercise any expiring equity or index call or put in a customer account that is $0.01 or more in-the-money at expiration. However, a specific brokerage firm's threshold for such automatic exercise may or may not be the same as OCC's (although most are). For example, if you own a call option with a strike price of $50, and the stock closes at $50.01 on the day your call expires, your broker will most likely exercise your option.

The Risks of Options Assignment

Any trader holding a short option position should understand the risks of early assignment. An early assignment occurs when a trader is forced to buy or sell stock when the short option is exercised by the long option holder. Understanding how assignment works can help a trader take steps to reduce their potential losses.

Understanding the basics of assignment

An option gives the owner the right but not the obligation to buy or sell stock at a set price. An assignment forces the short options seller to take action. Here are the main actions that can result from an assignment notice:

• Short call assignment: The option seller must sell shares of the underlying stock at the strike price.
• Short put assignment: The option seller must buy shares of the underlying stock at the strike price.

For traders with long options positions, it's possible to choose to exercise the option, buying or selling according to the contract before it expires. With a long call exercise, shares of the underlying stock are bought at the strike price while a long put exercise results in selling shares of the underlying stock at the strike price.

When a trader might get assigned

There are two components to the price of an option: intrinsic 1 and extrinsic 2  value. In the case of exercising an in-the-money 3 (ITM) long call, a trader would buy the stock at the strike price, which is lower than its prevailing price. In the case of a long put that isn't being used as a hedge for a long stock position, the trader shorts the stock for a price higher than its prevailing price. A trader only captures an ITM option's intrinsic value if they sell the stock (after exercising a long call) or buy the stock (after exercising a long put) immediately upon exercise.

Without taking these actions, a trader takes on the risks associated with holding a long or short stock position. The question of whether a short option might be assigned depends on if there's a perceived benefit to a trader exercising a long option that another trader has short. One way to attempt to gauge if an option could be potentially assigned is to consider the associated dividend. An options seller might be more likely to get assigned on a short call for an upcoming ex-dividend if its time value is less than the dividend. It's more likely to get assigned holding a short put if the time value has mostly decayed or if the put is deep ITM and close to expiration with a wide bid/ask spread on the stock.

It's possible to view this information on the Trade page of the thinkorswim ® trading platform. Review past dividends, the price of the short call, and the price of the put at the call's strike price. While past performance cannot be relied upon to continue, this information can help a trader determine whether assignment is more or less likely.

Reducing the risk associated with assignment

If a trader has a covered call that's ITM and it's assigned, the trader will deliver the long stock out of their account to cover the assignment.

A trader with a call vertical spread 4 where both options are ITM and the ex-dividend date is approaching may want to exercise the long option component before the ex-dividend date to have long stock to deliver against the potential assignment of the short call. The trader could also close the ITM call vertical spread before the ex-dividend date. It might be cheaper to pay the fees to close the trade.

Another scenario is a call vertical spread where the ITM option is short and the out-of-the-money (OTM) option is long. In this case, the trader may consider closing the position or rolling it to a further expiration before the ex-dividend date. This move can possibly help the trader avoid having short stock on the ex-dividend date and being liable for the dividend.

Depending on the situation, a trader long an ITM call might decide it's better to close the trade ahead of the ex-dividend date. On the ex-dividend date, the price of the stock drops by the amount of the dividend. The drop in the stock price offsets what a trader would've earned on the dividend and there would still be fees on top of the price of the put.

Assess the risk

When an option is converted to stock through exercise or assignment, the position's risk profile changes. This change could increase the margin requirements, or subject a trader to a margin call, 5 or both. This can happen at or before expiration during early assignment. The exercise of a long option position can be more likely to trigger a margin call since naked short option trades typically carry substantial margin requirements.

Even with early exercise, a trader can still be assigned on a short option any time prior to the option's expiration.

1  The intrinsic value of an options contract is determined based on whether it's in the money if it were to be exercised immediately. It is a measure of the strike price as compared to the underlying security's market price. For a call option, the strike price should be lower than the underlying's market price to have intrinsic value. For a put option the strike price should be higher than underlying's market price to have intrinsic value.

2  The extrinsic value of an options contract is determined by factors other than the price of the underlying security, such as the dividend rate of the underlying, time remaining on the contract, and the volatility of the underlying. Sometimes it's referred to as the time value or premium value.

3  Describes an option with intrinsic value (not just time value). A call option is in the money (ITM) if the underlying asset's price is above the strike price. A put option is ITM if the underlying asset's price is below the strike price. For calls, it's any strike lower than the price of the underlying asset. For puts, it's any strike that's higher.

4  The simultaneous purchase of one call option and sale of another call option at a different strike price, in the same underlying, in the same expiration month.

5  A margin call is issued when the account value drops below the maintenance requirements on a security or securities due to a drop in the market value of a security or when buying power is exceeded. Margin calls may be met by depositing funds, selling stock, or depositing securities. A broker may forcibly liquidate all or part of the account without prior notice, regardless of intent to satisfy a margin call, in the interests of both parties.

Option Assignment Process

Options trading 101 - the ultimate beginners guide to options.

Download The 12,000 Word Guide

One of the biggest fears that new options traders have is that they may get assigned. The option assignment process means that the option writer is obligated to deliver on the terms specified in a contract.

For example, if a put option is assigned, the options writer would need to buy the underlying security at the strike price dictated in the contract.

Likewise for a call option, the options write would need to sell the underlying security at the strike price dictated in the contract.

As an options trader you’re usually seeking to make a profit from directional bets or to hedge your portfolio.

You’re rarely, if ever, looking to actually buy or sell the underlying security so being assigned can sound like a scary prospect.

This article will explore the option assignment process so you can understand how it works and how you can prevent yourself getting stuck with buying or selling an underlying security.

When Assignment Occurs

Assignment occurs when an option holder exercises an option. Exercising an option simply means that the option holder executes the terms in the options contract.

So for example if you are holding a call option, you have the right, but not the obligation to buy the underlying security at the agreed strike price.

When you exercise the option, the option holder will need to sell the underlying security at the agreed strike price and for the agreed quantity.

If you’re dealing with European style options, you will know when expiration is possible because they can only be exercised on the expiration date itself.

For American style options, which is what most people trade, options can be exercised at any time before the expiration date.

This means that if you are an options writer of American style options, you could theoretically be asked at any time to comply with the terms of the contract.

Unfortunately, there is no knowing when an assignment will take place.

However, generally options are not exercised prior to expiration as it is usually much more profitable to sell the option instead.

It’s worth noting that this will only happen to you if you’re an options seller. Option buyers can never be assigned.

There are two key steps to assignment and to make it fair, the process of selecting who is assigned is random.

In the first step, the Options Clearing Corporation (OCC) will issue an exercise notice to a randomly selected Clearing Member who maintains an account with the OCC.

In the second step, the Clearing Member then assigns the exercise notice to an individual account.

When You Are Most At Risk

There are several situations that can dramatically increase the risk that you will be assigned:

Situation 1: Your option is In The Money (ITM)

When an option is ITM, an option holder would stand to profit if they exercised the option.

The deeper the option is ITM, the greater the profit for the option holder and therefore the higher risk they may exercise the option and you will be assigned.

Situation 2: The option has an upcoming dividend

An ITM call buyer can profit from exercising an option before its ex-dividend date if the extrinsic value of the call is less than the amount of the dividend.

Situation 3: There is no extrinsic value left

If there is no extrinsic value left, an option buyer could be tempted to exercise the option.

If there is extrinsic value, an option buyer would typically make a bigger profit by selling the option and buying/selling shares of the underlying asset.

How You Can Avoid The Risk Of Being Assigned

There are several steps you can take to avoid, or at the very least minimise, your risk of being assigned.

The first step to consider is avoiding selling any options that have an upcoming dividend.

Before selling any option, first check that the underlying security doesn’t have an upcoming dividend and if it does, consider waiting until after the dividend has occurred (i.e. the stock has gone ex-dividend).

If you do end up selling an option with an upcoming dividend, then the second step to protecting yourself is to close your position early as your risk begins to increase.

For example, if you are short an option with an extrinsic value less than the dividend amount and the ex-dividend of the underlying security is not too far away, close your position.

Otherwise you risk being assigned and being forced to pay the dividend as well!

To completely avoid early assignment risk, you could always sell only European style options which are cash settled at expiration. You can read more that here and here .

The final way to manage your risk is to close positions well before expiration date approaches.

As the time left to expiration decreases, so too does the extrinsic value. For option buyers, it means they could stand to benefit and so there is a risk they may exercise the option.

While this article deals with the process and risks behind being assigned, there will be times when this isn’t an issue for you.

Provided you have enough capital to meet the assignment, you may be fine with being assigned.

If this is the case, you would simply have a new stock position added which you could hold onto or immediately liquidate.

In the event that you don’t have enough capital, your broker will issue you with a margin call and the position should be automatically closed.

As the process of assignment can differ between brokers, its best you contact your broker to check the specific process they use when issuing assignments to individual accounts.

In general, provided you take a few key steps to mitigate your risks, particularly around dividend issuing securities, the chances of assignment are very low.

What is Options Assignment & How to Avoid It

If you are learning about options, assignment might seem like a scary topic. In this article, you will learn why it really isn’t. I will break down the entire options assignment process step by step and show you when you might be assigned, how to minimize the risk of being assigned, and what to do if you are assigned.

Video Breakdown of Options Assignment

Check out the following video in which I explain everything you need to know about assignment:

What is Assignment?

To understand assignment, we must first remember what options allow you to do. So let’s start with a brief recap:

• A call option gives its buyer the right to buy 100 shares of the underlying at the strike price
• A put option gives its buyer the right to sell 100 shares of the underlying at the strike price

In other words, call options allow you to call away shares of the underlying from someone else, whereas a put option allows you to put shares in someone else’s account. Hence the name call and put option.

The assignment process is the selection of the other party of this transaction. So the person that has to buy from or sell to the option buyer that exercised their option.

Note that an option buyer has the right to exercise their option. It is not an obligation and therefore, a buyer of an option can never be assigned. Only option sellers can ever be get assigned since they agree to fulfill this obligation when they sell an option.

Let’s go through a specific example to clarify this:

• The underlying security is stock ABC and it is trading at $100.
• Peter decides to buy 1 put option with a strike price of 95 as a hedge for his long stock position in ABC
• Kate sells this exact same option at the same time.

Over the next few weeks, ABC’s price goes down to $90 and Peter decides to exercise his put option. This means that he uses his right to sell 100 shares of ABC for $95 per share. Now Kate is assigned these 100 shares of ABC which means she is obligated to buy them for $95 per share. 

Peter now has 100 fewer shares of ABC in his portfolio, whereas Kate has 100 more.

This process is analog for a call option with the only difference being that Kate would be short 100 shares and Peter would have 100 additional shares of ABC in his portfolio.

Hopefully, this example clarifies what assignment is.

Who Can Be Assigned?

To answer this question, we must first ask ourselves who exercises their option? To do this, let’s quickly look at the different ways that you can close a long option position:

• Sell the option: Selling an option is probably the easiest way to close a long option position. Doing this will have no effect on the option seller.
• Let the option expire: If the option is Out of The Money , it would expire worthless and there would be no consequence for the option seller. If, on the other hand, the option is In The Money by more than $0.01, it would typically be automatically exercised . This would start the options assignment process.
• Exercise the option early: The last possibility would be to exercise the option before its expiration date. This, however, can only be done if the option is an American-style option. This would, once again, lead to an option assignment.

So as an option seller, you only have to worry about the last two possibilities in which the buyer’s option is exercised. 

But before you worry too much, here is a quick fact about the distribution of these 3 alternatives:

Less than 10% of all options are exercised.

This means 90% of all options are either sold prior to the expiration date or expire worthless. So always remember this statistic before breaking your head over the risk of being assigned.

It is very easy to avoid the first case of being assigned. To avoid it, just close your short option positions before they expire (ITM). For the second case, however, things aren’t as straight forward.

Who Risks being Assigned Early?

Firstly, you have to be trading American-style options. European-style options can only be exercised on their expiration date. But most equity options are American-style anyway. So unless you are trading index options or other kinds of European-style options, this will be the case for you.

Secondly, you need to be an options seller. Option buyers can’t be assigned.

These two are necessary conditions for you to be assigned. Everyone who fulfills both of these conditions risks getting assigned early. The size of this risk, however, varies depending on your position. Here are a few things that can dramatically increase your assignment risk:

• ITM: If your option is ITM, the chance of being assigned is much higher than if it isn’t. From the standpoint of an option buyer, it does not make sense to exercise an option that isn’t ITM because this would lead to a loss. Nevertheless, it is possible. The deeper ITM the option is, the higher the assignment risk becomes.
• Dividends : Besides that, selling options on securities with upcoming dividends also increases your risk of assignment. More specifically, if the extrinsic value of an ITM call option is less than the amount of the dividend, option buyers can achieve a profit by exercising their option before the ex-dividend date. 
• Extrinsic Value: Otherwise, keep an eye on the extrinsic value of your option. If the option has extrinsic value left, it doesn’t make sense for the option buyer to exercise their option because they would achieve a higher profit if they just sold the option and then bought or sold shares of the underlying asset. Typically, the less time an option has left, the lower its extrinsic value becomes. Implied volatility is another factor that influences extrinsic value.
• Puts vs Calls: This is more of an interesting side note than actual advice, but put options tend to get exercised more often than call options. This makes sense since put options give their buyer the right to sell the underlying asset and can, therefore, be a very useful hedge for long stock positions.

How can you Minimize Assignment Risk?

Since you now know what assignment is, and who risks being assigned, let’s shift our focus on how to minimize the assignment risk. Even though it isn’t possible to completely remove the risk of being assigned, there are things that you can do to dramatically decrease the chances of being assigned.

The first thing would be to avoid selling options on securities with upcoming dividend payments. Before putting on a position, simply check if the underlying security has any upcoming dividend payments. If so, look for a different trade.

If you ever are in the position that you are short an option and the ex-dividend of the underlying security is right around the corner, compare the size of the dividend to the extrinsic value of your option. If the extrinsic value is less than the dividend amount, you really should consider closing the position. Otherwise, the chances of being assigned are high. This is especially bad since being short during a dividend payment of a security will force you to pay the dividend.

Besides avoiding dividends, you should also close your option positions early. The less time an option has left, the lower its extrinsic value becomes and the more it makes sense for option buyers to exercise their options. Therefore, it is good practice to close your (ITM) short option positions at least one week before the expiration date.

The deeper an option is ITM, the higher the chances of assignment become. So the just-mentioned rule is even more important for deep ITM options.

If you don’t want to indefinitely close your position, it is also possible to roll it out to a later expiration cycle. This will give you more time and add extrinsic value to your position.

FAQs about Assignment

Last but not least, I want to answer some frequently asked questions about options exercise and assignment.

1. What happens if your account does not have enough buying power to cover the assigned position?

This is a common worry for beginning options traders. But don’t worry, if you don’t have enough capital to cover the new position, you will receive a margin call and usually, your broker will just automatically close the assigned shares immediately. This might lead to a minor assignment fee, but otherwise, it won’t significantly affect your account. Tatsyworks, for example, charges an assignment fee of only $5.

Check out my review of tastyworks

2. How does assignment affect your P&L?

When an option is exercised, the option holder gains the difference between the strike price and the price of the underlying asset. If the option is ITM, this is exactly the intrinsic value of the option. This means that the option holder loses the extrinsic value when he exercises his/her option. That’s also why it doesn’t make sense to exercise options with a lot of extrinsic value left.

This means that as soon as the option is exercised, it is only the intrinsic value that is relevant for the payoff. This is the same payoff as the option at its expiration date.

So as an options seller, your P&L isn’t negatively affected by an assignment. Either it stays the same or it becomes slightly better due to the extrinsic value being ignored.

As an example, if your option is ITM by $1, you will lose up to $100 per option or $1 per share that you are assigned. But this does not account for the extrinsic value that falls away with the exercise of the option. So this would be the same P&L as at expiration. Depending on how much premium you collected when selling the option, this might still be a profit or a minor loss.

With that being said, as soon as you are assigned, you will have some carrying risk. If you don’t or can’t close the position immediately, you will be exposed to the ongoing price fluctuations of that security.  Sometimes, you might not be able to close the new position immediately because of trading halts, or because the market is closed.

If you weren’t planning on holding that security, it is a good idea to close the new position as soon as possible. 

Option spreads such as vertical spreads, add protection to these price fluctuations since you can just exercise the long option to close the assigned share position at the strike price of the long option.

3. When an option holder exercises their option, how is the assignment partner chosen?

This is usually a random process. As soon as an option is exercised, the responsible brokerage firm sends a request to the Options Clearing Corporation (OCC). They send back the requested shares, whereafter they randomly choose another brokerage firm that currently has a client that is short the exercised option. Then the chosen broker has to decide which of their clients is assigned. This choice is, once again, random or a time-based priority system is used.

4. How does assignment work for index options?

As there aren’t any shares of indexes, you can’t directly be assigned any shares of the underlying asset. Therefore, index options are cash-settled. This means that instead of having to buy or sell shares of the underlying, you simply have to pay the difference between the strike price and the underlying trading price. This makes assignment easier and a lot less likely among index options.

Note that ETF options such as SPY options are not cash-settled. SPY is a normal security with openly traded shares, so exercise and assignment work just like they do among equity options.

I hope this article made you realize that assignment isn’t as bad as it might seem at first. It is just important to understand how the options assignment process works and what affects the likelihood of being assigned.

To recap, here’s what you should to do when you are assigned:

if you have enough capital in your account to cover the position, you could either treat the new position as a normal (stock) position and hold on to it or you could close it immediately. If you don’t have a clear trading plan for the new position, I recommend the latter.

If, on the other hand, you don’t have enough buying power, you will receive a margin call from your broker and the position should be closed automatically.

Assignment does not have any significant impact on your P&L, but it comes with some carrying risk. Options spreads can offer more protection against this than naked option positions.

To mitigate assignment risk, you should close option positions early, always keep an eye on the extrinsic value of your option positions, and avoid upcoming dividend securities.

And always remember, less than 10% of options are exercised, so assignment really doesn’t happen that often, especially not if you are actively trying to avoid it.

For the specifics of how assignment is handled, it is a good idea to contact your broker, as the procedures can vary from broker to broker.

hi there well seems like finally there is one good honest place. seem like you are puting on the table the whole truth about bad positions. however my wuestion is when can one know where to put that line of limit. when do you recognise or understand that you are in a bad position? thanks and once again, a great site.

Well If you are trading a risk defined strategy the point would be at max loss and not too much time left until expiration. For undefined risk strategies however it can be very different. I would just say if you don’t have too much time until expiration and are far from making money you should use some common sense and admit that you are wrong.

What would happen in the event of a crash. Would brokers be assigning, options, cashing out these shares, and making others bankrupt. Well, I guessed I sort of answered my own question. Its not easy to understand, especially not knowing when this would come up. But seems like you hit the important aspects of the agreement.

Actually I wouldn’t imagine that too many people would want to exercise their options in case of a market ctash, because they probably wouldn’t want to hold stocks in this risky and volatile environment. 

And to the part of the questions: making others bankrupt. This really depends on the situation. You can’t get assigned more stock than your option covers. This means as long as you trade with reasonable position sizing nothing too bad can happen. Otherwise I would recommend to trade with defined risk strategies so your maximum drawdown is capped.

Thanks for writing about assignment Louis. After reading the section how assignment works, I feel I am somewhat unclear about how assignment works when the exerciser exercises Put or Call option. In both cases, if the underlying is an index, is the settlement done through the margin account money? Would you be able to provide a little more detail of how exercising the option (Put vs Call) would work in case of an underlying stock vs Index.

Thank you very much in advance

Thanks for the question. Indexes can’t be traded in the same way as stocks can. That’s why index options are settled in cash. If your index option is assigned, you won’t have to buy or sell any shares of the underlying index at the strike price because there exist no shares of indexes. Instead, you have to pay the amount that your index option is ITM to the exerciser of your option. Let me give you an example: You are short a call option with the strike price of 1000. The underlying asset is an index and it’s price is 1050. This means your call option is 50 points ITM. If someone exercises your long call option, you will have to pay him/her the difference between the strike price and the underlying’s price which would be 50 (1050-1000). So the main difference between index and stock options is that you don’t have to buy/sell any shares of the underlying asset for index options. I hope this helps. Please let me know if you have any other questions or comments.

Can the same logic be applied for ETFs as it does Indexes? For example, if I trade the SPY ETF, would it be settled in cash?

Thanks! Johnson

Hi Johnson, Exercise and assignment for ETFs such as SPY work just like they do for equities. ETFs have shares that are openly traded, whereas indexes don’t. That’s why indexes are settled in cash, whereas ETFs aren’t. I hope this helps.

There are many articles online that I read that are biased against options tradings and I am a bit surprised to read a really helpful article like this. I find this helpful in understanding options trading, what are the techniques and how to manage the risks. Before, I was hesitant to try this financial game but now, after reading this article, I am considering participating with live accounts and no longer with a demo account. A few months ago, I signed up with a company called IQ Options, but really never involved real money and practiced only with a demo account.

Thanks for your comment. I am glad to see that you liked the post. However, I don’t recommend sing IQ Option to trade since they are a very shady trading firm. You could check out my  Review of IQ Option for all the details.

this is a great and amazing article. i sincerely your effort creating time  to write on such an informative article which has taught me a lot more on what is options assignment and avoiding it. i just started trading but had no ideas on this as a beginner. i find this article very helpful because it has given me more understanding on options trading and knowing the techniques and how to manage the risks. thanks for sharing this amazing article

You are very welcome

Hello, the first thing that i noticed when i opened this page is the beauty of the website. i am sure you have put much effort into creating this article and the details are really clear here. after watching the video break down, i fully understood the entire process on how to avoid options assignment.

Thank you so much for the positive feedback!

I would love to create a website like yours as the design used is really nice, simple and brings about clarity of the write ups, but then you wrote a brilliant article on how to avoid options assignment. great video here. it was  confusing at first. i will suggest another video be added to help some people like me.

Thanks for the feedback. I recommend checking out my  options trading beginner course . In it, I cover all the basics that weren’t explained here.

Thanks for your very helpful article. I am contemplating selling a call that would cover half my shares on company X. How can ensure that the assignment process selects the shares that I bought at a higher price, so as to maximize capital losses?

Hi Luis, When you are assigned, you just automatically buy/sell shares of the underlying at the strike price. This means your overall portfolio is adjusted by these 100 shares. The exact shares and your entry price are irrelevant. If you have 50 shares of X and your short call is assigned, you will sell 100 shares of X at the strike price. After this, your position would be -50 shares of X which would be equivalent to being short 50 shares of X. I hope this helps.

Louis, I entered a CALL butterfly spread at $100 below where I intended, just 2 days before expiration date. I intended to speculate on a big earning announcement jump the next day. It was a debit of 1.25. Also, when I realized my mistake, I tried to close it for anything at all. The Mark fluctuated between 40 and 70, but I could not get it to close. So now I am assigned to sell 200 share at 70 dollars below the market price of the stock. I am having a heart attack. I do not have the 200 shares to deliver, so it seems I have to buy them at the market, and sell them for $70 less, for a loss of $14,000.

What other options are open to me? Can my trading firm force a close with a friendly market maker and make it as if it happened on Friday? I am willing to pay a friendly market maker several hundred dollars to make this trade. Is that an option? Other options the trading firm can do for me that would cost me less than $14,000?

Hi Paul, Thanks for your comment. From the limited information provided, it is hard to say what is actually going on. If you bought a call butterfly spread, your max loss should be limited to the premium you paid to open the position. An assignment shouldn’t have a huge impact on your overall P&L. I highly recommend contacting your broker and explaining your situation to them since they have all the information required to evaluate what’s actually going on. But if the loss is real, there is no way for you to make a deal with a market maker to limit or undo potential losses. I hope this helps.

What happens with ITM long call option that typically gets automatically exercised at expiration, if the owner of the call option doesn’t have the cash/margin to cover the stock purchase?

He would receive a margin call

Understanding assignment risk in Level 3 and 4 options strategies

E*TRADE from Morgan Stanley

With all options strategies that contain a short option position, an investor or trader needs to keep in mind the consequences of having that option assigned , either at expiration or early (i.e., prior to expiration). Remember that, in principle, with American-style options a short position can be assigned to you at any time. On this page, we’ll run through the results and possible responses for various scenarios where a trader may be left with a short position following an assignment.

Before we look at specifics, here’s an important note about risk related to out-of-the-money options: Normally, you would not receive an assignment on an option that expires out of the money. However, even if a short position appears to be out of the money, it might still be assigned to you if the stock were to move against you just prior to expiration or in extended aftermarket or weekend trading hours. The only way to eliminate this risk is to buy-to-close the short option.

• Short (naked) calls

Credit call spreads

Credit put spreads, debit call spreads, debit put spreads.

• When all legs are in-the-money or all are out-of-the-money at expiration

Another important note : In any case where you close out an options position, the standard contract fee (commission) will be charged unless the trade qualifies for the E*TRADE Dime Buyback Program . There is no contract fee or commission when an option is assigned to you.

Short (naked) call

If you experience an early assignment

An early assignment is most likely to happen if the call option is deep in the money and the stock’s ex-dividend date is close to the option expiration date.

If your account does not hold the shares needed to cover the obligation, an early assignment would create a short stock position in your account. This may incur borrowing fees and make you responsible for any dividend payments.

Also note that if you hold a short call on a stock that has a dividend payment coming in the near future, you may be responsible for paying the dividend even if you close the position before it expires.

An early assignment generally happens when the put option is deep in the money and the underlying stock does not have an ex-dividend date between the current time and the expiration of the option.

Short call + long call

(The same principles apply to both two-leg and four-leg strategies)

This would leave your account short the shares you’ve been assigned, but the risk of the position would not change . The long call still functions to cover the short share position. Typically, you would buy shares to cover the short and simultaneously sell the long leg of the spread.

Pay attention to short in-the-money call legs on the day prior to the stock’s ex-dividend date, because an assignment that evening would put you in a short stock position where you are responsible for paying the dividend. If there’s a risk of early assignment, consider closing the spread.

Short put + long put

Early assignment would leave your account long the shares you’ve been assigned. If your account does not have enough buying power to purchase the shares when they are assigned, this may create a Fed call in your account.

However, the long put still functions to cover the position because it gives you the right to sell shares at the long put strike price. Typically, you would sell the shares in the market and close out the long put simultaneously.

Here's a call example

• Let’s say that you’re short a 100 call and long a 110 call on XYZ stock; both legs are in-the-money.
• You receive an assignment notification on your short 100 call, meaning you sell 100 shares of XYZ stock at 100. Now, you have $10,000 in short stock proceeds, your account is short 100 shares of stock, and you still hold the long 110 call.
• Exercise your long 110 call, which would cover the short stock position in your account.
• Or, buy 100 shares of XYZ stock (to cover your short stock position) and sell to close the long 110 call.

Here's a put example:

• Let’s say that you’re short a 105 put and long a 95 put on XYZ stock; the short leg is in-the-money.
• You receive an assignment notification on your short 105 put, meaning you buy 100 shares of XYZ stock at 105. Now, your account has been debited $10,500 for the stock purchase, you hold 100 shares of stock, and you still hold the long 95 put.
• The debit in your account may be subject to margin charges or even a Fed call, but your risk profile has not changed.
• You can sell to close 100 shares of stock and sell to close the long 95 put.

Long call + short call

Debit spreads have the same early assignment risk as credit spreads only if the short leg is in-the-money.

An early assignment would leave your account short the shares you’ve been assigned, but the risk of the position would not change . The long call still functions to cover the short share position. Typically, you would buy shares to cover the short share position and simultaneously sell the remaining long leg of the spread.

Long put + short put

An early assignment would leave your account long the shares you’ve been assigned. If your account does not have enough buying power to purchase the shares when they are assigned, this may create a Fed call in your account.

All spreads that have a short leg

(when all legs are in-the-money or all are out-of-the-money)

Pay attention to short in-the-money call legs on the day prior to the stock’s ex-dividend date because an assignment that evening would put you in a short stock position where you are responsible for paying the dividend. If there’s a risk of early assignment, consider closing the spread.

However, the long put still functions to cover the long stock position because it gives you the right to sell shares at the long put strike price. Typically, you would sell the shares in the market and close out the long put simultaneously.

Ready for Options Trading? Make Sure You Understand Assignment First

Your first assignment: decoding this important options term before you start trading.

The options market can seem to have a language of its own. To the average investor, there are likely a number of unfamiliar terms, but for an individual with a short options position—someone who has sold call or put options—there is perhaps no term more important than " assignment "—the fulfilling of the requirements of an options contract.

When someone buys options to open a new position ("Buy to Open"), they are buying a  right —either the right to buy the underlying security at a specified price (the strike price) in the case of a call option, or the right to sell the underlying security in the case of a put option.

On the flip side, when an individual sells, or writes, an option to open a new position ("Sell to Open"), they are accepting an  obligation —either an obligation to sell the underlying security at the strike price in the case of a call option or the obligation to buy that security in the case of a put option. When an individual sells options to open a new position, they are said to be "short" those options. The seller does this in exchange for receiving the option's premium from the buyer.

American-style options allow the buyer of a contract to exercise at any time during the life of the contract, whereas European-style options can be exercised only during a specified period just prior to expiration. For an investor selling American-style options, one of the risks is that the investor may be called upon at any time during the contract's term to fulfill its obligations. That is, as long as a short options position remains open, the seller may be subject to "assignment" on any day equity markets are open. 

What is assignment?

An option assignment represents the seller's obligation to fulfill the terms of the contract by either selling or buying the underlying security at the exercise price. This obligation is triggered when the buyer of an option contract exercises their right to buy or sell the underlying security.

To ensure fairness in the distribution of American-style and European-style option assignments, the Options Clearing Corporation (OCC), which is the options industry clearing house, has an established process to randomly assign exercise notices to firms with an account that has a short option position. Once a firm receives an assignment, it then assigns this notice to one of its customers who has a short option contract of the same series. This short option contract is selected from a pool of such customers, either at random or by some other procedure specific to the brokerage firm. 

How does an investor know if an option position will be assigned?

While an option seller will always have some level of uncertainty, being assigned may be a somewhat predictable event. Only about 7% of options positions are typically exercised, but that does not imply that investors can expect to be assigned on only 7% of their short positions. Investors may have some, all or none of their short positions assigned.

And while the majority of American-style options exercises (and assignments) happen on or near the contract's expiration, a long options holder can exercise their right at any time, even if the underlying security is halted for trading. Someone may exercise their options early based upon a significant price movement in the underlying security or if shares become difficult to borrow as the result of a pending corporate action such as a buyout or takeover. 

Note: European-style options can only be exercised during a specified period just prior to expiration. In U.S. markets, the majority of options on commodity and index futures are European-style, while options on stocks and exchange-traded funds (ETF) are American-style. So, while SPDR S&P 500 , or SPY options, which are options tied to an ETF that tracks the S&P 500, are American-style options, S&P 500 Index options, or SPX options, which are tied to S&P 500 futures contracts, are European-style options.

What happens after an option is assigned?

An investor who is assigned on a short option position is required to meet the terms of the written option contract upon receiving notification of the assignment. In the case of a short equity call, the seller of the option must deliver stock at the strike price and in return receives cash. An investor who doesn't already own the shares will need to acquire and deliver shares in return for cash in the amount of the strike price, multiplied by 100, since each contract represents 100 shares. In the case of a short equity put, the seller of the option is required to purchase the stock at the strike price.

How might an investor's account balance fluctuate after opening a short options position?

It is normal to see an account balance fluctuate after opening a short option position. Investors who have questions or concerns or who do not understand reported trade balances and assets valuations should contact their brokerage firm immediately for an explanation. Please keep in mind that short option positions can incur substantial risk in certain situations.

What does "XYZ July 50" mean? XYZ = the ticker symbol of the security July = the month when the option will expire 50 = $50, the strike price on the option

For example, say XYZ stock is trading at $40 and an investor sells 10 contracts for XYZ July 50 calls at $1.00, collecting a premium of $1,000, since each contract represents 100 shares ($1.00 premium x 10 contracts x 100 shares). Consider what happens if XYZ stock increases to $60, the call is exercised by the option holder and the investor is assigned. Should the investor not own the stock, they must now acquire and deliver 1,000 shares of XYZ at a price of $50 per share. Given the current stock price of $60, the investor's short stock position would result in an unrealized loss of $9,000 (a $10,000 loss from delivering shares $10 below current stock price minus the $1,000 premium collected earlier).

Note: Even if the investor's short call position had not been assigned, the investor's account balance in this example would still be negatively affected—at least until the options expire if they are not exercised. The investor's account position would be updated to reflect the investor's unrealized loss—what they  could  lose if an option is exercised (and they are assigned) at the current market price. This update does not represent an actual loss (or gain) until the option is actually exercised and the investor is assigned. 

What happens if an investor opened a multi-leg strategy, but one leg is assigned?

American-style option holders have the right to exercise their options position prior to expiration regardless of whether the options are in-, at- or out-of-the-money. Investors can be assigned if any market participant holding calls or puts of the same series submits an exercise notice to their brokerage firm. When one leg is assigned, subsequent action may be required, which could include closing or adjusting the remaining position to avoid potential capital or margin implications resulting from the assignment. These actions may not be attractive and may result in a loss or a less-than-ideal gain.

If an investor's short option is assigned, the investor will be required to perform in accordance with their obligation to purchase or deliver the underlying security, regardless of the overall risk of their position when taking into account other options that may be owned as part of the overall multi-leg strategy. If the investor owns an option that serves to limit the risk of the overall spread position, it is up to the investor to exercise that option or to take other action to limit risk. 

Below are a couple of examples that underscore how important it is for every investor to understand the risks associated with potential assignment during market hours and potentially adverse price movements in afterhours trading.

Example #1: An investor is short March 50 XYZ puts and long March 55 XYZ puts. At the close of business on March expiration, XYZ is priced at $56 per share, and both puts are out of the money, which means they have no intrinsic value. However, due to an unexpected news announcement shortly after the closing bell, the price of XYZ drops to $40 in after-hours trading. This could result in an assignment of the short March 50 puts, requiring the investor to purchase shares of XYZ at $50 per share. The investor would have needed to exercise the long March 55 puts in order to realize the gain on the initial multi-leg position. If the investor did not exercise the March 55 puts, those puts may expire and the investor may be exposed to the loss on the XYZ purchase at $50, a $10 per share loss with XYZ now trading at $40 per share, without receiving the benefit of selling XYZ at $55.

Example #2: An investor is short March 50 XYZ puts and long April 50 XYZ puts. At the close of business on March expiration, XYZ is priced at $45 per share, and the investor is assigned XYZ stock at $50. The investor will now own shares of XYZ at $50, along with the April 50 XYZ puts, which may be exercised at the investor's discretion. If the investor chooses not to exercise the April 50 puts, they will be required to pay for the shares that were assigned to them on the short March 50 XYZ puts until the April 50 puts are exercised or shares are otherwise disposed of.

Note: In either example, the short put position may be assigned prior to expiration at the discretion of the option holder. Investors can check with their brokerage firm regarding their option exercise procedures and cut-off times.

Expiration, exercise, and assignment

Unlike stocks, options have set expiration , exercise , and assignment dates.

Each option contract has a set expiration date. This date significantly impacts the value of the option contract because it limits the time you can buy, sell, or exercise the option contract. Once an option contract expires, it will stop trading and either be exercised or expire worthless.

The following are a few important things to keep in mind as the expiration date of an option contract approaches:

• We’ll attempt to exercise any option you own that is $0.01 or more in-the-money, as long as your investment account has the required buying power, such as for a call option, or the necessary underlying shares to sell, such as for a put option. Keep in mind that managing your options positions, including taking proactive steps to mitigate risk, is ultimately your responsibility.
• If you don’t have enough buying power or underlying shares to exercise your option, we may attempt to sell the contract in the market for you within the last 30 minutes before the market closes on the options' expiration date. However, we may also take action on a position outside of that 30-minute window based on market conditions.
• Robinhood’s risk checks are designed to close positions based on the position’s value, the implied risk, and your current account portfolio and value, among other things.

Moneyness of an option

In-the-money, at-the-money, and out-of-the-money refer to the position of the underlying security’s price relative to the strike price of the option. They’re also sometimes referred to as the moneyness of an option.

To learn more, check out Options trading from the pros .

If your option is in-the-money at the market’s close, Robinhood will attempt to exercise it for you at expiration unless:

• You don’t have sufficient buying power.
• The exercise would result in a short stock position.
• You’ve asked Robinhood to submit a Do Not Exercise (DNE) request on your behalf. Keep in mind, the cut-off time for submitting a DNE request is 5 PM ET.

Once your contract expires, it’ll move to your expired contracts in your account History .

After-hours price movements can change the in-the-money or out-the-money status of an options contract.

If for any reason we can't sell your contract, and you don’t have the necessary buying power or shares to exercise it, we may attempt to submit a DNE request to the Options Clearing Corporation (OCC), and your contract should expire worthless.

To determine if an option position is “at risk of being in-the-money,” Robinhood will calculate an estimated upper and lower bound for the underlying security’s close price on the expiration date. If your option’s strike price falls within these parameters, we may place an order to close your position.

If your option is in-the-money, Robinhood will typically exercise it for you at expiration automatically. However, you can also exercise your options contract early in the app:

• Navigate to the options position detail screen
• Select Exercise

You’ll then be guided through steps to exercise your contract.

Before expiration day, an early exercise request will be submitted immediately if it’s placed during regular market hours (9 AM-4 PM ET) and trading days. Contact us before 5 PM ET if you’d like to cancel an exercise request.

Early exercise requests submitted after 4 PM ET will be queued for the next trading day. You can cancel a pending exercise request until 11:59 PM ET.

On expiration day, you won’t be able to submit an early exercise request in the app or on the web after 4 PM ET. Contact us to request an exercise request after 4 PM ET. We’ll try to accommodate exercise requests until 5 PM ET on a best-effort basis.

How to confirm

After you exercise an option, you’ll get an in-app confirmation that your option was exercised and that the associated shares are pending. You’ll also get an email and an in-app notification before the next trading day confirming that your option was exercised or assigned (after we receive confirmation from the OCC).

How to submit a DNE

If your option is out-of-the-money at the close, Robinhood will take no action and the contract will typically expire. If you’d like to submit a DNE request, you must contact us before 5 PM on the expiration date .

When you are assigned, you have the obligation to fulfill the terms of the contract. When you sell-to-open an options contract, you can be assigned at any point prior to expiration (regardless of the underlying share price).

Depending on the collateral held for a short contract, a few different things can occur. For more details, check out Navigating exercise & assignment .

Check out Basic options strategies (Level 2) and Advanced options strategies (Level 3) to learn more about calls, puts, and multi-leg options strategies.

Unassigned anticipated assignment

On rare occasions, the in-the-money short option of a spread won’t get assigned. This happens when the counterparty files a DNE request for their in-the-money option, or a post-market movement shifts the option from in-the-money to out-of-the-money (and the contract holder decides not to exercise). In this scenario, you’ll likely be long or short the stock the following trading day, potentially resulting in an account deficit or margin call.

All resulting short stock positions must be covered the following trading day.

The scenario listed above could result in a gain or loss that’s greater than theoretical max gain or loss on the position.

Early assignment

If you’re trading a multi-leg options strategy and are assigned a short position before expiration, keep the following in mind, such as any account deficits or margin calls .

Decreased buying power

Early assignment may result in decreased buying power. This is because the positions you hold are used to calculate your buying power, and at the time you’re assigned, you may not have the shares (for call spreads) or the buying power (for put spreads) needed to cover the deficit in your account. If you have an account deficit, you can’t open new positions until the deficit is resolved.

Account deficits

Early assignment may also result in an account deficit if it causes you to use more buying power than you have available. When you have an account deficit, there are a few potential actions that you can take, including exercising your long contract or buying/selling shares. If you have an account deficit and choose to exercise your long contract to increase your buying power, you will not be able to open new positions while your exercise is pending. But you should be able to open new positions once your exercise has been processed if exercising your long contract is sufficient to cover your account deficit.

Margin calls

Early assignment may also result in margin call if it causes your account value to fall below your margin maintenance requirement. When you have a margin call, there are a few potential actions that you can take: exercising your long contract, buying/selling shares by placing orders, or depositing enough funds to cover the margin call. If you have a margin call and choose to exercise your long contract to decrease your margin deficiency, your margin call may persist while your exercise is pending or, further, if the exercise was not sufficient enough to cover your margin deficit. If exercising your long contract is sufficient to cover your margin deficiency, any margin calls should be satisfied once your exercise is processed.

Early assignment and exercise

Keep in mind that we can’t process an early assignment before the end of the trading day and, so we can’t exercise the long leg until the next trading day (at the earliest). That’s because the Options Clearing Corporation (OCC) doesn’t notify us of your assignment until after the market closes (when they process assignments). While funds and shares that result from exercises are made available immediately during market hours, positions exercised after market hours are queued and credited to your account the next trading day.

Pending shares

If an option is exercised before expiration.

A few things can happen if your option is exercised early (also known as an early-exercise), depending on the time of day.

If the early exercise occurs during market hours (9 AM-4 PM ET), the associated shares will show in your account immediately, and will no longer show as a pending exercise in your account.

If the early exercise occurs after 4 PM ET, it’ll be queued for the next trading day, and the associated shares will remain pending until the exercise has cleared.

Some underlying assets (like exchange-traded products) are eligible for late-close options trading until 4:15 PM ET. Check out Options trading hours for details.

If a long option exercised or assigned at expiration

Once your contract has been exercised or assigned, we’ll hold the associated shares or cash collateral until we receive confirmation from the OCC that all aspects of the exercise or assignment have cleared. This process typically takes 1 business day. Once completed, the pending state of the exercise or assignment will be removed and your account will be updated accordingly.

• Select History

Options dividend risk

Dividend risk is the risk that you’ll get assigned on a short call position (either as part of a covered call or spread) the trading day before the underlying security’s ex-dividend date. If this happens and you don’t own 100 shares of the stock, you’ll open the ex-date with a short stock position and actually be responsible for paying that dividend yourself. You can potentially avoid this by closing any position that includes a short call option at any time before the end of regular market hours on the trading day before the ex-date.

Robinhood may take action in your brokerage account to close any positions that have dividend risk the trading day before an ex-dividend date. Generally, we’ll only take action if the dividend that would be owed upon assignment represents a large portion of your total account value, which we’ll try to do on a best-effort basis.

Options dividend example

Let’s say, XYZ is going to pay a dividend as follows:

• Ex-date: October 1
• Record date: October 2
• Pay date: October 31

If you’re short, or you’ve sold an option call contract for XYZ that’s expiring on or after October 1, you’re at risk of an assignment.

For example, if you get assigned on September 30, you’d have a short position of 100 shares that were exercised by the counterparty (a person who bought and exercised the call option) when the market opens on October 1. If this occurs, you’ll have to deliver the underlying shares and pay the counterparty the dividend that is associated with these shares.

In this example, you’d owe a dividend of $100, which is $1 x 100 shares. We’d automatically deduct the dividend amount from your account, even if it causes you to have a negative balance.

You can avoid this dividend risk by closing your option before the market closes on any trading day before the ex-dividend date.

The day before the ex-dividend, we’ll try to prevent you from selling to open new short call options that are likely to be assigned that same night if the underlying symbol ex-dividend date occurs on the next trading day. This is only temporary, and you can open new short call positions on or after the ex-dividend date.

Options Assignment

How can i tell when i will be assigned.

You can never tell when you will be assigned. Once you sell an American-style option (put or call), you have the potential for assignment to fulfill your obligation to receive (and pay for) or deliver (and are paid for) shares of stock on any business day. In some circumstances, you may be assigned on a short option position while the underlying shares are halted for trading, or perhaps while they are the subjects of a buyout or takeover.

To ensure fairness in the distribution of equity and index option assignments, OCC utilizes a random procedure to assign exercise notices to clearing member accounts maintained with OCC. The assigned firm must then use an exchange-approved method (usually a random process or the first-in, first-out method) to allocate notices to its accounts that are short the options.

Some generalizations might help you understand likelihood of assignment on a short-option position:

• Option holders only exercise about 7% of options. The percentage hasn't varied much over the years. That does not mean that you can only be assigned on 7% of your short option. It means that, in general, option exercises are not that common.
• The majority of option exercises (and the corresponding assignments) occurs as the option gets closer to expiration. It usually doesn't make sense to exercise an option, which has any time premium over intrinsic value. For most options, that doesn't occur until close to expiration.
• In general terms, an investor is more likely to exercise a put that goes in-the-money than a call that goes in-the-money. Why? Think about the result of an exercise. An investor who exercises a put uses it to sell shares and receive cash. A person exercising a call option uses it to buy shares and must pay cash. Option holders are more likely to exercise options if it means they can receive cash sooner. The opposite is true for calls, where exercise means you have to pay cash sooner.

The bottom line is that you really don't have any sure-fire way to predict when you will be assigned on a short option position. It can happen any day the stock market is open for trading.

OCC encourages all investors to inform their brokerage firm of their exercise intentions for their long options at expiration. While each firm may have their own thresholds, OCC employs an administrative procedure where options that are $.01 in-the-money are exercised unless contrary instructions are provided. Customers and brokers should check with their firm's operations department to determine their company's policies regarding exercise thresholds.

An option holder has the right to exercise their option regardless of the price of the underlying security. It is a good practice for all option holders to express their exercise (or non-exercise) instructions to their broker. Is there a magic number that ensures that option writers will not be assigned? No. Although unlikely, an investor may choose to exercise a slightly out-of-the-money option or choose not to exercise an option that is in-the-money by greater than $.01.

Some investors use the saying, "when in doubt, close them out.” This means that if they buy back any short contracts, they are no longer at risk of assignment.

I wrote a slightly out-of-the-money covered call. the call has since moved in-the-money. is there any way to avoid assignment on that short call, if i buy-to-close a short option position, how can i be sure i will not be assigned.

You will want to first check with your broker to ensure that an assignment has not already occurred.

Because OCC processes closing buy transactions before exercises, there is no possibility of being assigned on positions that were closed during that day's trading hours.

When I sell an option to open, is my only chance of assignment (and being required to fulfill my...

When i sell an option to open, is my only chance of assignment (and being required to fulfill my obligations as the option writer) when the person or entity that bought from me decides to exercise.

No. There are several reasons why this is untrue. First, the buy side of your opening sale could have been a closing purchase by someone who was already short the option. Second, OCC allocates assignments randomly. Anyone short that particular option is at risk of assignment when an option holder decides to exercise. Third, assuming the other side of your trade was an opening purchase, they may sell to close at any time but since you are still short, you are at risk of assignment.

As long as you keep a short option position open, you are at risk of assignment. Assignment risk increases as the option becomes deeper in-the-money and as expiration approaches (the option trades with less time premium). Assignment risk also increases just before the ex-dividend date for short calls and just after the ex-dividend date for short puts.

At expiration, OCC exercises all equity options that are in-the-money by $.01 or more unless the option holder instructs their broker not to exercise or the stock has been removed from OCC’s exercise-by-exception processing.

The Mechanics of Option Trading, Exercise, and Assignment

Options were originally traded in the over-the-counter ( OTC ) market , where the terms of the contract were negotiated. The advantage of the OTC market over the exchanges is that the option contracts can be tailored: strike prices, expiration dates, and the number of shares can be specified to meet the needs of the option buyer. However, transaction costs are greater and liquidity is less.

Option trading really took off when the first listed option exchange — the Chicago Board Options Exchange ( CBOE )— was organized in 1973 to trade standardized contracts, greatly increasing the market and liquidity of options. The CBOE was the original exchange for options, but, by 2003, it has been superseded in size by the electronic Nasdaq International Securities Exchange (ISE), based in New York. Most options sold in Europe are traded through electronic exchanges. Other exchanges for options in the United States include: New York Stock Exchange , and the NASDAQtrader.com .

Option exchanges are central to the trading of options:

• they establish the terms of the standardized contracts
• they provide the infrastructure — both hardware and software — to facilitate trading, which is increasingly computerized
• they link together investors, brokers, and dealers on a centralized system, so that traders get the best bid/ask prices
• they guarantee trades by taking the opposite side of each transaction
• they establish the trading rules and procedures

Options are traded just like stocks — the buyer buys at the ask price and the seller sells at the bid price . The settlement time for option trades is 1 business day ( T+1 ). However, to trade options, an investor must have a brokerage account and be approved for trading options and must also receive a copy of the booklet Characteristics and Risks of Standardized Options .

The option holder, unlike the holder of the underlying stock, has no voting rights in the corporation, and is not entitled to any dividends. Brokerage commissions are still charged for options even though the commissions for stocks have been free for a while. Prices for most options range from $0.65 to $1 per contract .

The Options Clearing Corporation (OCC)

The Options Clearing Corporation ( OCC ) is the counterparty to all option trades. The OCC issues, guarantees, and clears all option trades involving its member firms, including all U.S. option exchanges, and ensures that sales are transacted according to the current rules. The OCC is jointly owned by its member firms — the exchanges that trade options — and issues all listed options, and controls and effects all exercises and assignments. To provide a liquid market, the OCC guarantees all trades by acting as the other party to all purchases and sales of options.

The OCC, like other clearing companies, is the direct participant in every purchase and sale of an option contract. When an option writer or holder sells his contracts to someone else, the OCC serves as an intermediary in the transaction. The option writer sells his contract to the OCC and the option buyer buys it from the OCC.

The OCC publishes statistics, news on options, and any notifications about changes in the trading rules, or the adjustment of certain option contracts because of a stock split or that were subjected to unusual circumstances, such as a merger of companies whose stock was the underlying security to the option contracts.

The OCC operates under the jurisdiction of both the Securities and Exchange Commission ( SEC ) and the Commodities Futures Trading Commission ( CFTC ). Under its SEC jurisdiction, OCC clears transactions for put and call options on common stocks and other equity issues, stock indexes, foreign currencies, interest rate composites and single-stock futures . As a registered Derivatives Clearing Organization ( DCO ) under CFTC jurisdiction, the OCC clears and settles transactions in futures and options on futures .

The Exercise of Options by Option Holders and the Assignment to Fulfill the Contract to Option Writers

When an option holder wants to exercise his option, he must notify his broker of the exercise, and if it is the last trading day for the option, the broker must be notified before the exercise cut-off time , which will probably be earlier than on trading days before the last day, and the cut-off time may differ for different option classes or for index options. Although policies differ among brokerages, it is the duty of the option holder to notify his broker to exercise the option before the cut-off time.

When the broker is notified, then the exercise instructions are sent to the OCC, which then assigns the exercise to one of its Clearing Members who are short in the same option series as is being exercised. The Clearing Member will then assign the exercise to one of its customers who is short in the option. The customer is selected by a specific procedure, usually on a first-in, first-out basis, or some other fair procedure approved by the exchanges. Thus, there is no direct connection between an option writer and a buyer.

To ensure contract performance, option writers are required to post margin, the amount depending on how much the option is in the money. If the margin is deemed insufficient, then the option writer will be subjected to a margin call. Option holders don't need to post margin because they will only exercise the option if it is in the money. Options, unlike stocks, cannot be bought on margin.

Because the OCC is always a party to an option transaction, an option writer can close out his position by buying the same contract back, even while the contract buyer retains his position, because the OCC draws from a pool of contracts with no connection to the original contract writer and buyer.

A diagram outlining the exercise and assignment of a call.

Example: No Direct Connection between Investors Who Write Options and those Who Buy Them

John Call-Writer writes an option that legally obligates him to provide 100 shares of JXYZ for the price of $30 until April. The OCC buys the contract, adding it to the millions of other option contracts in its pool. Sarah Call-Buyer buys a contract that has the same terms that John Call-Writer wrote — in other words, it belongs to the same option series . However, option contracts have no name on them. Sarah buys from the OCC, just as John sold to the OCC, and she just gets a contract giving her the right to buy 100 shares of JXYZ for $30 per share until April.

Scenario 1 — Exercises of Options are Assigned According to Specific Procedures

In February, the price of JXYZ rises to $35, and Sarah thinks it might go higher in the long run, but since March and April generally are volatile times for most stocks, she decides to exercise her call (sometimes called calling the stock ) to buy JXYZ stock at $30 per share to hold the stock indefinitely. She instructs her broker to exercise her call; her broker forwards the instructions to the OCC, which then assigns the exercise to one of its participating members who provided the call for sale; the participating member, in turn, assigns it to an investor who wrote such a call; in this case, it happened to be John's brother, Sam Call-Writer. John got lucky this time. Sam, unfortunately, either must turn over his appreciated shares of JXYZ, or he'll have to buy them in the open market to provide them. This is the risk that an option writer must take — an option writer never knows when he'll be assigned an exercise when the option is in the money.

Scenario 2 — Closing Out an Option Position by Buying Back the Contract

John Call-Writer decides that JXYZ might climb higher in the coming months, and so decides to close out his short position by buying a call contract with the same terms that he wrote — one that is in the same option series. Sarah, on the other hand, decides to maintain her long position by keeping her call contract until April. This can happen because there are no names on the option contracts. John closes his short position by buying the call back from the OCC at the market price, which may be higher or lower than what he paid, resulting in either a profit or a loss. Sarah can keep her contract because when she sells or exercises her contract, it will be with the OCC, not with John, and Sarah can be sure that the OCC will fulfill the terms of the contract if she exercises it later.

Thus, the OCC allows each investor to act independently of the other .

When the assigned option writer must deliver stock, she can deliver stock already owned, buy it on the market for delivery, or ask her broker to go short on the stock and deliver the borrowed shares. However, finding borrowed shares to short may not always be possible, so this method may not be available.

If the assigned call writer buys the stock in the market for delivery, the writer only needs the cash in his brokerage account to pay for the difference between what the stock cost and the strike price of the call, since the writer will immediately receive cash from the call holder for the strike price. Similarly, if the writer is using margin, then the margin requirements apply only to the difference between the purchase price and the strike price of the option. Full margin requirements, however, apply to shorted stock.

An assigned put writer will need either the cash or the margin to buy the stock at the strike price, even if he intends to sell the stock immediately after the exercise of the put. When the call holder exercises, he can keep the stock or immediately sell it. However, he must have the margin, if he has a margin account, or cash, for a cash account, to pay for the stock, even if he sells it immediately. He can also use the delivered stock to cover a short in the stock. (Note: equity requirements differ because an assigned call writer immediately receives the cash upon delivery of the shares, whereas a put writer or a call holder who purchased the shares may decide to keep the stock.)

Example: Fulfilling a Naked Call Exercise

A call writer receives an exercise notice on 10 call contracts with a strike of $30 per share on JXYZ stock on which she is still short. The stock currently trades at $35 per share. She does not own the stock, so, to fulfill her contract, she must buy 1,000 shares of stock in the market for $35,000 then sell it for $30,000, resulting in an immediate loss of $5,000 minus the commissions of the stock purchase and assignment.

Both the exercise and assignment incur brokerage commissions for both holder and assigned writer. Generally, the commission is smaller to sell the option than it is to exercise it. However, there may be no choice if it is the last day of trading before expiration. Both the buying and selling of options and the exercise or assignment are settled in 1 business day after the trade ( T+1 ).

Often, a writer will want to cover his short by buying the written option back on the open market. However, once he receives an assignment, then it is too late to cover his short position by closing the position with a purchase. Assignment is usually selected from writers still short at the end of the trading day. A possible assignment can be anticipated if the option is in the money at expiration, the option is trading at a discount, or the underlying stock is about to pay a large dividend.

The OCC automatically exercises any option that is in the money by at least $0.01 ( automatic exercise , Exercise-by-Exception , Ex-by-Ex ), unless notified by the broker not to. A customer may not want to exercise an option that is only slightly in the money if the transaction costs would exceed the net profit from the exercise. Despite the automatic exercise by the OCC, the option holder should notify his broker by the exercise cut-off time , which may be before the end of the trading day, of an intent to exercise. Exact procedures depend on the broker.

Any option that is sold on the last trading day before expiration would likely be bought by a market maker. Because a market maker's transaction costs are lower than for retail customers, a market maker may exercise an option even if it is only a few cents in the money. Thus, any option writer who does not want to be assigned should close out his position before expiration day if there is any chance that it will be in the money even by a few pennies.

Early Exercise

Sometimes, an option will be exercised before its expiration day — called early exercise , or premature exercise . Because options have a time value in addition to intrinsic value, most options are not exercised early. However, there is nothing to prevent someone from exercising an option, even if it is not profitable to do so, and sometimes it does occur, which is why anyone who is short an option should expect the possibility of being assigned early.

When an option is trading below parity (below its intrinsic value), then arbitrageurs can take advantage of the discount to profit from the difference, because their transaction costs are very low. An option with a high intrinsic value will have little time value, and so, because of the difference between supply and demand in the market at any given moment, the option could be trading for less than its true worth. An arbitrageur will almost certainly take advantage of the price discrepancy for an instant profit. Anyone who is short an option with a high intrinsic value should expect a good possibility of being assigned an exercise.

Example: Early Exercise by Arbitrageurs Profiting from an Option Discount

JXYZ stock is currently at $40 per share. Calls on the stock with a strike of $30 are selling for $9.80. This is a difference of $0.20 per share, enough of a difference for an arbitrageur, whose transaction costs are typically much lower than for a retail customer, to profit immediately by selling short the stock at $40 per share, then covering his short by exercising the call for a net of $0.20 per share minus the arbitrageur's small transaction costs.

Option discounts will only occur when the time value of the option is small, because either it is deep in the money or the option will soon expire.

Option Discounts Arising from an Imminent Dividend Payment on the Underlying Stock

When a large dividend is paid by the underlying stock, its price drops on the ex-dividend date, resulting in a lower value for the calls. The stock price may remain lower after the payment, because the dividend payment lowers the book value of the company. This causes many call holders to either exercise early to collect the dividend, or to sell the call before the drop in stock price. When many call holders sell at once, the calls sell at a discount to the underlying, creating opportunities for arbitrageurs to profit from the price difference. However, there is risk the transaction will lose money, because the dividend payment and drop in stock price may not equal the premium paid for the call, even if the dividend exceeds the time value of the call.

Example: Arbitrage Profit/Loss Scenario for a Dividend-Paying Stock

JXYZ stock is currently trading at $40 per share and will pay a dividend of $1 the next day. A call with a $30 strike is selling for $10.20, the $0.20 being the time value of the premium. So an arbitrageur decides to buy the call and exercise it to collect the dividend. Since the dividend is $1, but the time value is only $0.20, this could lead to a profit of $0.80 per share, but on the ex-dividend date, the stock drops to $39. Adding the $1 dividend to the share price yields $40, which is still less than buying the stock for $30 + $10.20 for the call. It might be profitable if the stock does not drop as much on the ex-date or it recovers after the ex-date sufficiently to make it profitable. But this is a risk for the arbitrageur, and this transaction is, thus, called risk arbitrage , because the profit is not guaranteed.

2019 Statistics for the Fate of Options

Data Source: https://www.optionseducation.org/referencelibrary/faq/options-exercise

All option writers who didn't close out their position earlier by buying an offsetting contract made the maximum profit — the premium — on those contracts that expired. Option writers have lost at least something when the option is exercised, because the option holder wouldn't exercise it unless it was in the money. The more the exercised option was in the money, the greater the loss is for the assigned option writer and the greater the profits for the option holder. A closed out transaction could be at a profit or a loss for both holders and writers of options, but closing out a transaction is usually done either to maximize profits or to minimize losses, based on expected changes in the price of the underlying security until expiration.
