Model Insight
With persistence 0.999, volatility shocks have a half-life of 627 trading days (~2.5 years), close to a unit root, so long-run forecasts are highly sensitive to this estimate. Returns follow a Student-t distribution with v = 3.08 degrees of freedom, capturing fatter tails than a normal distribution.
