How Does the Concept of “Greeks” Relate to the Black-Scholes Model?
The "Greeks" are a set of risk parameters derived as partial derivatives of the option pricing model, such as Black-Scholes. They measure the sensitivity of an option's price to small changes in the model's inputs.
For example, Delta measures sensitivity to the underlying price, and Vega measures sensitivity to volatility. Traders use the Greeks to manage the risk of their options portfolio.
