Understanding Options Expiration – Expiration Cycles

All option contracts have a shelf life. That is, they are valid and useful for a certain span of time to a certain date. That date is called the expiry date as mentioned in other pages of this website. On this expiration date, the options contract becomes invalid and no longer useful to a trader. On the options expiration date, the holder of the option no longer has the right to exercise the option.

Why does this matter to you? 

When you are holding onto an option that is nearing its expiration date, you should be certain that a price move in the underlying security would increase the option premium enough for you to sell it at a profit. When an options contract is nearing its expiration date, the there is a significant decline in its time value. Do take note of this. If you are a holder of an options contract that is going to expire soon, the underlying price moves must effect a positive change in the option premium so as to offset the loss in time value. 

When do stock options expire in the US?

Stock options in the United States expire on the third Friday of the expiration month. If the third Friday of the expiration month is a public holiday, the expiration date would be adjusted to the day before. that is, the expiration date becomes Thursday.
