In options contracts, the strike price (or exercise price) is the fixed price at which the holder of the option can buy (in the case of a call option) or sell (in the case of a put option) the underlying asset upon expiration or before, depending on the type of option. It is a crucial component of options pricing, as it determines the potential profitability of the option if exercised. For instance, a call option with a strike price of $50 will only be profitable if the market price of the underlying asset exceeds $50 at or before expiration.
