Zomma Gamma Volatility

Calculation

Zomma Gamma Volatility represents a second-order approximation of an option’s sensitivity to changes in underlying asset volatility, building upon the foundational Gamma metric. It quantifies how much an option’s Gamma will change with a one-percent shift in implied volatility, providing insight into the convexity of the volatility surface. This metric is particularly relevant for sophisticated derivatives traders managing portfolios with substantial option positions, as it aids in understanding and mitigating risks associated with volatility fluctuations. Accurate calculation requires a robust pricing model and careful consideration of the underlying asset’s volatility term structure.
