## What Is the Difference between Historical and Implied Volatility?

Historical volatility is a backward-looking measure, calculated from the past price movements of the underlying asset over a specific period. Implied volatility (IV) is a forward-looking measure, derived from the current market price of the option using a pricing model.

IV represents the market's expectation of future volatility.
