Expiration Date

Definition

The expiration date is the specific date at which an option contract becomes void and can no longer be exercised. It is a critical feature in the realm of financial derivatives, particularly options, as it defines the time limit within which the holder must decide whether to exercise their right to buy or sell the underlying asset at the predetermined strike price. The expiration date directly affects the time value of an option and plays a significant role in pricing and trading strategies.
