Jan 2, 1990 to Sep 11, 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 = 0.78 sits below 2, so large shocks influence volatility less than quadratically, a more outlier-robust response than standard GARCH.
