Model Insight

This asset exhibits a notable leverage effect: negative returns increase next-day volatility 100% more than equivalent positive returns. The volatility power δ = 2.28 sits above 2, so large shocks influence volatility more than quadratically, dominating the response more than in standard GARCH.
