How Does Gamma Behave for ATM Options?

Gamma is typically highest for at-the-money (ATM) options. High gamma means the option's delta is most sensitive to changes in the underlying asset's price.

Since ATM options are on the cusp of moving ITM or OTM, their delta changes most rapidly with small price moves, leading to the highest gamma value.
