Expiration date

The day on which an option contract becomes void. For stock options expiring prior to February 15, 2015, this date is the Saturday immediately following the third Friday of the expiration month. For stock options expiring on or after February 15, 2015, this date is the third Friday of the expiration month. Brokerage firms, however, may set an earlier deadline for notification of an option buyer's intention to exercise. If Friday is a holiday, the last trading day will be the preceding Thursday. See also Expiration Time and Automatic Exercise.

This is a definition, not a recommendation. Options carry risk and can expire worthless. See how the desk actually trades at TrueTrader.
