Feb 24, 2020 to Aug 21, 2026Model Insight
With persistence 0.993, volatility shocks have a half-life of 101 trading days (~0.4 years), close to a unit root, so long-run forecasts are highly sensitive to this estimate. Returns follow a Student-t distribution with v = 2.54 degrees of freedom, capturing fatter tails than a normal distribution.
