← Options Glossary The likelihood in percentage terms that a stock or index will land above or below some price on the day of expiration. The probability of expiring doesn't care about what happens between now and expiration. It only considers the probability that the stock will be above some higher price or below some lower price at expiration.
Probability of Expiring
This is a definition, not a recommendation. Options carry risk and can expire worthless. See how the desk actually trades at TrueTrader.
