Model Insight

This asset exhibits a notable leverage effect: negative returns increase next-day volatility 69% more than equivalent positive returns. 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.
