Non-Linear Sensitivities

Variance

These are the non-constant sensitivities of an option’s price (or a portfolio’s P&L) to changes in underlying parameters, most notably volatility, which is captured by Vega and its higher-order derivatives. Unlike linear exposures like Delta, these measures change as the underlying price or implied volatility moves, requiring dynamic re-hedging. Understanding the curvature of these sensitivities is essential for managing non-linear payoff structures.
