BREAKING DOWN 'Expiration Date (Derivatives)'. The expiration date for all listed stock options in the United States is normally the third Friday of the contract month, which is the month when the contract expires.However, when that Friday falls on a holiday, the expiration date is on the Thursday immediately before the third Friday.Once an options or futures contract passes its expiration date, the contract is invalid.owever, when that Friday falls on a holiday, the expiration date is on the Thursday immediately before the third Friday. Once an options or futures contract passes its expiration date, the contract is invalid.
Simply count the days (calendar days) on your option period, and the end date occurs at 11:59pm on the last day of the option period. For example, if the execution date were the 14th, and the contract had a 10-day option period, then the option period should end at 11:59pm on the 24th. Good luck, Jeffrey.
