Model Insight

Volatility shocks decay with a half-life of 19 trading days, meaning a shock loses half its impact after approximately 19 days. The volatility power δ = 1.06 sits below 2, so large shocks influence volatility less than quadratically, a more outlier-robust response than standard GARCH.
