Jun 25, 2025 to Aug 7, 2026Model Insight
Volatility shocks decay with a half-life of 8 trading days, meaning a shock loses half its impact after approximately 8 days. The volatility power δ = 0.50 sits below 2, so large shocks influence volatility less than quadratically, a more outlier-robust response than standard GARCH.
