Mar 21, 1991 to Jul 17, 2026Model Insight
This asset exhibits a modest leverage effect: negative returns increase next-day volatility 24% more than equivalent positive returns. The volatility power δ = 1.52 sits below 2, so large shocks influence volatility less than quadratically, a more outlier-robust response than standard GARCH.
