The Variance Gamma model is a stochastic process used for pricing options that addresses the limitations of the Black-Scholes model by incorporating non-normal return distributions. This model allows for a more accurate representation of real-world market dynamics, specifically the presence of “fat tails” and skewness in asset returns. It assumes that price changes follow a Brownian motion subordinated to a gamma process.
Distribution
Unlike the Black-Scholes model’s assumption of log-normal returns, the Variance Gamma model captures the empirical observation that asset returns often exhibit leptokurtosis, meaning extreme events are more likely than predicted by a normal distribution. The model’s parameters allow for separate control over skewness and kurtosis, providing a more flexible framework for modeling asset price movements.
Pricing
The Variance Gamma model is particularly useful for pricing options in markets with high volatility and frequent jumps, such as cryptocurrency derivatives. By accurately modeling the non-normal distribution of returns, the model provides more precise valuations for out-of-the-money options and better estimates of risk metrics. This advanced approach helps quantitative analysts develop more robust hedging strategies.
