Greeks Vanna Volga

Definition

Vanna and Volga are higher-order Greeks that quantify the sensitivity of an option’s delta and vega, respectively, to changes in implied volatility. Vanna measures the rate of change of delta with respect to a change in implied volatility, or equivalently, the rate of change of vega with respect to a change in the underlying asset price. Volga, also known as Vomma, measures the rate of change of vega with respect to a change in implied volatility. These metrics are critical for managing complex options portfolios.
