Parameter Estimates

May 3, 2019 to Aug 14, 2026

Model Insight

With persistence 0.999, volatility shocks have a half-life of 511 trading days (~2.0 years), close to a unit root, so long-run forecasts are highly sensitive to this estimate. The volatility power δ = 2.30 sits above 2, so large shocks influence volatility more than quadratically, dominating the response more than in standard GARCH.
