Dec 30, 2025 to Jul 10, 2026Model Insight
This asset exhibits a notable leverage effect: negative returns increase next-day volatility 63% more than equivalent positive returns. The volatility power δ = 1.60 sits below 2, so large shocks influence volatility less than quadratically, a more outlier-robust response than standard GARCH.
