Nov 28, 2003 to Oct 8, 2026Model Insight
With persistence 0.995, volatility shocks have a half-life of 140 trading days (~0.6 years), close to a unit root, so long-run forecasts are highly sensitive to this estimate. Returns follow a Student-t distribution with v = 4.17 degrees of freedom, capturing fatter tails than a normal distribution.
