Volatility and Time Decay Effects Implied volatility and time to expiration are key determinants of gamma’s magnitude.
Non Linear Dynamics Hedging in Option Gamma Behavior
A portfolio with positive gamma benefits from large moves in the underlying, as the hedge becomes more effective as prices move favorably, while losses are cushioned when the market moves against the position. 10, indicating that delta will change by 0.
