Option Exercise and Assignment Explained w/ Visuals

Last updated on February 11th, 2022 , 06:38 am

Buyers of options have the right to exercise their option at or before the option’s expiration. When an option is exercised, the option holder will buy (for exercised calls) or sell (for exercised puts) 100 shares of stock per contract at the option’s strike price.

Conversely, when an option is exercised, a trader who is short the option will be assigned 100 long (for short puts) or short (for short calls) shares per contract.

• Long American style options can exercise their contract at any time.
• Long calls transfer to +100 shares of stock
• Long puts transfer to -100 shares of stock
• Short calls are assigned -100 shares of stock.
• Short puts are assigned +100 shares of stock.
• Options are typically only exercised and thus assigned when extrinsic value is very low.
• Approximately only 7% of options are exercised.

The following sequences summarize exercise and assignment for calls and puts (assuming one option contract ):

Call Buyer Exercises Option   ➜  Purchases 100 shares at the call’s strike price.

Call Seller Assigned  ➜  Sells/shorts 100 shares at the call’s strike price.

Put Buyer Exercises Option  ➜  Sells/shorts 100 shares at the put’s strike price.

Put Seller Assigned   ➜  Purchases 100 shares at the put’s strike price.

Let’s look at some specific examples to drill down on this concept.

Exercise and Assignment Examples

In the following table, we’ll examine how various options convert to stock positions for the option buyer and seller:

As you can see, exercise and assignment is pretty straightforward: when an option buyer exercises their option, they purchase (calls) or sell (puts) 100 shares of stock at the strike price . A trader who is short the assigned option is obligated to fulfill the opposite position as the option exerciser. 

Automatic Exercise at Expiration

Another important thing to know about exercise and assignment is that standard in-the-money equity options are automatically exercised at expiration. So, traders may end up with stock positions by letting their options expire in-the-money.

An in-the-money option is defined as any option with at least $0.01 of intrinsic value at expiration . For example, a standard equity call option with a strike price of 100 would be automatically exercised into 100 shares of stock if the stock price is at $100.01 or higher at expiration.

What if You Don't Have Enough Available Capital?

Even if you don’t have enough capital in your account, you can still be assigned or automatically exercised into a stock position. For example, if you only have $10,000 in your account but you let one 500 call expire in-the-money, you’ll be long 100 shares of a $500 stock, which is a $50,000 position. Clearly, the $10,000 in your account isn’t enough to buy $50,000 worth of stock, even on 4:1 margin.

If you find yourself in a situation like this, your brokerage firm will come knocking almost instantaneously. In fact, your brokerage firm will close the position for you if you don’t close the position quickly enough.

Why Options are Rarely Exercised

At this point, you understand the basics of exercise and assignment. Now, let’s dive a little deeper and discuss what an option buyer forfeits when they exercise their option.

When an option is exercised, the option is converted into long or short shares of stock. However, it’s important to note that the option buyer will lose the extrinsic value of the option when they exercise the option. Because of this, options with lots of extrinsic value remaining are unlikely to be exercised. Conversely, options consisting of all intrinsic value and very little extrinsic value are more likely to be exercised.

The following table demonstrates the losses from exercising an option with various amounts of extrinsic value:

As we can see here, exercising options with lots of extrinsic value is not favorable. 

Why? Consider the 95 call trading for $7. Exercising the call would result in an effective purchase price of $102 because shares are bought at $95, but $7 was paid for the right to buy shares at $95. 

With an effective purchase price of $102 and the stock trading for $100, exercising the option results in a loss of $2 per share, or $200 on 100 shares.

Even if the 95 call was previously purchased for less than $7, exercising an option with $2 of extrinsic value will always result in a P/L that’s $200 lower (per contract) than the current P/L. F

or example, if the trader initially purchased the 95 call for $2, their P/L with the option at $7 would be $500 per contract. However, if the trader decided to exercise the 95 call with $2 of extrinsic value, their P/L would drop to +$300 because they just gave up $200 by exercising.

7% Of Options Are Exercised

Because of the fact that traders give up money by exercising an option with extrinsic value, most options are not exercised. In fact, according to the Options Clearing Corporation,  only 7% of options were exercised in 2017 . Of course, this may not factor in all brokerage firms and customer accounts, but it still demonstrates a low exercise rate from a large sample size of trading accounts.

So, in almost all cases, it’s more beneficial to sell the long option and buy or sell shares instead of exercising. We like to call this approach a “synthetic exercise.”

Congrats! You’ve learned the basics of exercise and assignment. If you’d like to know how the exercise and assignment process actually works, continue to the next section!

Who Gets Assigned When an Option is Exercised?

With thousands of traders long and short options in the market, who actually gets assigned when one of the traders exercises their option?

In this section, we’ll run through the exercise and assignment process for options so you know how the assignment decision occurs.

If a trader is short a single option, how do they get assigned if one of a thousand other traders exercises that option?

The short answer is that the process is random. For example, if there are 5,000 traders who are long a call option and 5,000 traders who are short that call option, an account with the short option will be randomly assigned the exercise notice. The random process ensures that the option assignment system is fair

Visualizing Assignment and Exercise

The following visual describes the general process of exercise and assignment:

If you’d like, you can read the OCC’s detailed assignment procedure here  (warning: it’s intense!).

Now you know how the assignment procedure works. In the final section, we’ll discuss how to quickly gauge the likelihood of early assignment on short options.

Assessing Early Option Assignment Risk

The final piece of understanding exercise and assignment is gauging the risk of early assignment on a short option.

As mentioned early, only 7% of options were exercised in 2017 (according to the OCC). So, being assigned on short options is rare, but it does happen. While a specific probability of getting assigned early can’t be determined, there are scenarios in which assignment is more or less likely.

The following scenarios summarize  broad generalizations  of early assignment probabilities in various scenarios:

In regards to the dividend scenario, early assignment on in-the-money short calls with less extrinsic value than the dividend is more likely because the dividend payment covers the loss from the extrinsic value when exercising the option.

All in all, the risk of being assigned early on a short option is typically very low for the reasons discussed in this guide. However, it’s likely that you will be assigned on a short option at some point while trading options (unless you don’t sell options!), but at least now you’ll be prepared!

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.

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.
