Model Insight

This asset exhibits a modest leverage effect: negative returns increase next-day volatility 32% more than equivalent positive returns. The volatility power δ = 2.54 sits above 2, so large shocks influence volatility more than quadratically, dominating the response more than in standard GARCH.
