Mathematically, it measures the convexity of the option's price curve, meaning it captures how the slope of the option value changes as the underlying moves. Rising volatility generally increases gamma for at-the-money options because the probability distribution spreads out, making delta more responsive.

Practical Applications for Traders Traders utilize gamma exposure strategically depending on their market outlook. Professional traders often visualize their gamma profile across strikes to ensure their portfolio is positioned to handle various market scenarios.
Conversely, a short gamma position, common for premium sellers, profits from stable, range-bound markets but carries the risk of catastrophic losses during sudden gaps. Foundations of Gamma in Options Pricing At its core, gamma is derived from the Black-Scholes-Merton framework, where it is defined as the second partial derivative of the option price with respect to the underlying asset price.

Conversely, as expiration approaches, gamma for at-the-money options spikes dramatically before collapsing to zero in the final moments, a phenomenon known as gamma squeeze. Consequently, high gamma environments often lead to increased volatility in the underlying market as these mechanical adjustments occur.
