Options Greeks Explained

Definition

Options Greeks are a set of standardized measures that quantify the sensitivity of an option’s price to changes in underlying market parameters. These include Delta (sensitivity to underlying price), Gamma (rate of change of Delta), Theta (sensitivity to time decay), Vega (sensitivity to implied volatility), and Rho (sensitivity to interest rates). Each Greek provides a specific insight into an option’s risk and reward profile. Understanding them is fundamental for effective options trading.
