Options Greeks: Gamma (Γ)

Gamma measures the rate of change in an option's delta for a $1 move in the underlying asset's price. This table reviews how gamma values typically correspond to an option's moneyness (how the strike price compares to the present market price) and sensitivity to price changes in the underlying asset.
