Model Insight

Volatility shocks decay with a half-life of 13 trading days, meaning a shock loses half its impact after approximately 13 days. The volatility power δ = 1.19 sits below 2, so large shocks influence volatility less than quadratically, a more outlier-robust response than standard GARCH.
