Feb 18, 2026 to Oct 16, 2026Model Insight
Volatility shocks decay with a half-life of 1 trading day, meaning a shock loses half its impact after approximately 1 day. The volatility power δ = 0.63 sits below 2, so large shocks influence volatility less than quadratically, a more outlier-robust response than standard GARCH.
