Volatility Jump Processes

Definition

Volatility Jump Processes refer to stochastic models where price paths experience abrupt, discontinuous shifts in variance, frequently observed in cryptocurrency markets as sudden liquidity vacuums or news-driven shocks. Unlike standard diffusion processes that assume continuous price movement, these models incorporate discrete jumps to capture the fat-tailed distributions and extreme kurtosis inherent in digital asset pricing. Traders and quantitative analysts utilize these frameworks to better assess tail risk, as they more accurately represent the reality of sudden regime changes during high-impact market events.
