Model Insight

This asset exhibits a modest leverage effect: negative returns increase next-day volatility 33% more than equivalent positive returns. The volatility power δ = 0.52 sits below 2, so large shocks influence volatility less than quadratically, a more outlier-robust response than standard GARCH.
