Apr 8, 2014 to Sep 25, 2026Model Insight
Volatility shocks decay with a half-life of 14 trading days, meaning a shock loses half its impact after approximately 14 days. The volatility power δ = 3.00 sits above 2, so large shocks influence volatility more than quadratically, dominating the response more than in standard GARCH.
