Oct 30, 2019 to Aug 14, 2026Model Insight
The news-impact curve is shifted (γ = -1.01) so that positive returns raise next-day volatility more than negative returns of the same size. Volatility rises more after gains than after losses, the reverse of the usual leverage effect and rare among risky assets.
