Mar 27, 2013 to Jul 10, 2026Model Insight
This asset shows a rare inverse leverage effect: positive returns raise next-day volatility 135% more than negative returns. Volatility rises more after gains than after losses, the reverse of the usual leverage effect and uncommon among risky assets. The volatility power δ = 2.28 sits above 2, so large shocks influence volatility more than quadratically, dominating the response more than in standard GARCH.
