Apr 16, 2004 to Aug 28, 2026Model Insight
This asset exhibits a strong leverage effect: negative returns increase next-day volatility 147% more than equivalent positive returns. The volatility power δ = 1.37 sits below 2, so large shocks influence volatility less than quadratically, a more outlier-robust response than standard GARCH.
