Non-Linear Volatility Structures

Volatility

Non-linear volatility structures describe how implied volatility, derived from options prices, varies across different strike prices and maturities for the same underlying asset. This phenomenon, often visualized as a “volatility smile” or “skew,” indicates that out-of-the-money options typically have higher implied volatility than at-the-money options. It deviates from the Black-Scholes assumption of constant volatility, reflecting market participants’ expectations of extreme price movements. This structure is dynamic and changes with market conditions.
