Implied volatility
In a Black-Scholes framework, the implied volatility of a financial security or basket of assets is the level of volatility that solves the underlying’s option pricing formula, where strike price, risk-free rate, time to maturity and underlying’s price are fixed inputs.
Implied volatility is considered a forward-looking risk measure, as it is calculated on observable variables which incorporate market expectations.
