Model Insight
With persistence 0.998, volatility shocks have a half-life of 286 trading days (~1.1 years), close to a unit root, so long-run forecasts are highly sensitive to this estimate. Returns follow a Student-t distribution with v = 4.73 degrees of freedom, capturing fatter tails than a normal distribution.
