Parameter Estimates

Jan 2, 1990 to Sep 11, 2026

Model Insight

With persistence 0.996, volatility shocks have a half-life of 163 trading days (~0.6 years), close to a unit root, so long-run forecasts are highly sensitive to this estimate. Returns follow a Student-t distribution with v = 6.66 degrees of freedom, capturing fatter tails than a normal distribution.
