May 20, 1992 to Oct 23, 2026Model Insight
This asset exhibits a modest leverage effect: negative returns increase next-day volatility 38% more than equivalent positive returns. The volatility power δ = 1.16 sits below 2, so large shocks influence volatility less than quadratically, a more outlier-robust response than standard GARCH.
