May 15, 2024 to Aug 7, 2026Model Insight
Volatility shocks decay with a half-life of 11 trading days, meaning a shock loses half its impact after approximately 11 days. The volatility power δ = 0.92 sits below 2, so large shocks influence volatility less than quadratically, a more outlier-robust response than standard GARCH.
