Model 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 = 0.50 sits below 2, so large shocks influence volatility less than quadratically, a more outlier-robust response than standard GARCH.
