Sep 23, 2021 to Jul 17, 2026Model Insight
Volatility shocks decay with a half-life of 16 trading days, meaning a shock loses half its impact after approximately 16 days. The volatility power δ = 1.48 sits below 2, so large shocks influence volatility less than quadratically, a more outlier-robust response than standard GARCH.
