Strike Price

In options, an agreed-upon price for which the underlying is bought (in case of a call) or sold (in case of a put) if the option is exercised. For a call option to be profitable, the strike price must be lower than the market value of the underlying at the time the option is exercised. The opposite is true for a put: the strike price must be higher than the market value. In most cases, the amount of the strike is stated in the option contract; however, in Asian options, the strike is a formula, rather than a set price. For example, the strike may be the average price of the underlying over a set period of time. The strike price is also known as the exercise price.

Strike price. The strike price, also called the exercise price, is the price at which you as an options holder can buy or sell the stock or other financial instrument underlying the options contract if you choose to exercise before expiration.

While the strike price is set by the exchange on which the option trades, and changes only if there's a stock split, merger, or some other corporate action that affects the underlying instrument, the market price of the underlying instrument rises and falls during the life of the contract.

As a result, the underlying instrument might reach a price that would put the strike price in-the-money and make exercising the option at the strike price, or selling the option in the marketplace financially advantageous, or it might not. If not, you let the option expire.
