Can You Exercise an Option Before Expiration?

Options contracts are financial tools that offer a buyer the right, but not the obligation, to engage in a transaction involving an underlying asset. A common question for those new to these contracts is whether this right can be exercised at any point during the option’s life or only when it reaches its expiration date.

Understanding Options

An option is a contract that gives its holder the choice to buy or sell an underlying asset at a predetermined price. This underlying asset can be stocks, exchange-traded funds (ETFs), or other financial instruments. Options derive their value from the price movements of these underlying assets.

There are two primary types of options: call options and put options. A call option grants the holder the right to buy the underlying asset at a specified price, known as the strike price. Conversely, a put option provides the holder with the right to sell the underlying asset at its strike price. Each option contract has an expiration date, the last day it can be exercised.

American and European Options

The ability to exercise an option before its expiration date depends entirely on its style. Options are broadly categorized into American-style and European-style. This distinction is not about geography, but rather the timing of when the option can be exercised.

American-style options offer flexibility, allowing the holder to exercise the contract at any time from the purchase date up to and including the expiration date. Most stock and ETF options listed in the United States are American-style. This means that if an American-style option is “in-the-money”—meaning it has intrinsic value—the holder can choose to act on it before it expires.

In contrast, European-style options are more restrictive, as they can only be exercised on their specified expiration date. Even if a European-style option is significantly in-the-money before expiration, the holder must wait until the final day to exercise their right. This key difference in exercise timing is a fundamental characteristic distinguishing the two option types.

Deciding on Early Exercise

For American-style options, early exercise is permitted but usually not financially advantageous for a holder. When an option is exercised early, any remaining “time value” is forfeited. Time value is the portion of an option’s premium reflecting the potential for favorable price movement before expiration. Selling the option in the open market instead of exercising it allows the holder to capture this remaining time value, often leading to higher profit.

Early exercise of a call option may be considered in specific situations, primarily related to dividends. If a significant dividend payment is approaching for the underlying stock, and a call option is deep in-the-money, exercising the call before the ex-dividend date allows the option holder to acquire the shares and receive the dividend. This decision makes sense only if the dividend outweighs the lost time value.

For put options, early exercise may be considered in scenarios with high interest rates. If interest rates are substantial, exercising an in-the-money put option allows the holder to sell the underlying stock and receive cash proceeds, which can then be invested to earn interest. The decision depends on whether the interest earned surpasses the put option’s remaining time value.

Option writers, those who sell options, face “assignment risk” when dealing with American-style options. This means they can be assigned an exercise notice and be obligated to fulfill their side of the contract at any time before expiration, even if the option holder exercises early. This risk increases as an option becomes deeper in-the-money or nears an ex-dividend date for call options. For most retail investors, selling an American-style option to close a position is more financially sound than early exercise, as it preserves remaining time value.
