Jan 2, 1990 to Sep 14, 2026Model Insight
Volatility shocks decay with a half-life of 15 trading days, meaning a shock loses half its impact after approximately 15 days. The volatility power δ = 0.57 sits below 2, so large shocks influence volatility less than quadratically, a more outlier-robust response than standard GARCH.
