Mar 9, 2026 to Sep 4, 2026Model Insight
Volatility shocks decay with a half-life of 5 trading days, meaning a shock loses half its impact after approximately 5 days. The volatility power δ = 1.17 sits below 2, so large shocks influence volatility less than quadratically, a more outlier-robust response than standard GARCH.
