The Greek Letters are used to measure the sensibility of a Stock Option’s price to various parameters. The parameters include, Stock Price, Volatility, Time to Expiration and Interest Rates.

To explain the sensibilities in the value of Stock Option Contracts, the various Greek letters Delta, Gamma, Vega, Theta and Rho are used. The objective is to explain the change in an Options Price, Puts and Calls, as the Stock Price changes.
