What Does a High Theta Value Imply for an Option’s Value?

Theta measures the rate at which an option's value decays as the time to expiration decreases. A high negative Theta value implies that the option is losing a significant portion of its value each day due0 to time decay.

This effect is most pronounced for at-the-money options close to expiration.
