With persistence 0.997, volatility shocks have a half-life of 201 trading days (~0.8 years), close to a unit root, so long-run forecasts are highly sensitive to this estimate. Returns follow a Student-t distribution with v = 2.95 degrees of freedom, capturing fatter tails than a normal distribution.
