Jan 31, 2005 to Oct 9, 2026Model Insight
This asset exhibits a strong leverage effect: volatility responds almost entirely to negative shocks. The ARCH response to positive shocks is negligible. The volatility power δ = 1.23 sits below 2, so large shocks influence volatility less than quadratically, a more outlier-robust response than standard GARCH.
