Option Greeks

Option Greeks are a set of mathematical risk measures — derived from options pricing models such as the Black-Scholes model — that quantify the sensitivity of an option's price to changes in various underlying parameters, enabling options traders to understand, measure, and manage the risk dimensions of their options positions. The primary Greeks are: Delta (sensitivity of option price to changes in the underlying asset price), Gamma (rate of change of Delta relative to the underlying price — the 'acceleration' of Delta), Theta (rate of option value decay due to the passage of time — also called time decay), Vega (sensitivity of option price to changes in implied volatility), and Rho (sensitivity to changes in interest rates). Higher-order Greeks such as Charm, Vanna, and Volga are used by institutional traders for precise hedging. For options traders on Ventura Securities' F&O platform, a working mastery of the Greeks is essential for constructing targeted strategies — managing directional risk (Delta), volatility exposure (Vega), time decay (Theta), and gamma risk in dynamic markets — and is foundational to professional-grade options portfolio management.
