Model Insight

With persistence 0.999, volatility shocks have a half-life of 685 trading days (~2.7 years), close to a unit root, so long-run forecasts are highly sensitive to this estimate. Returns follow a Student-t distribution with v = 4.18 degrees of freedom, capturing fatter tails than a normal distribution.
