May 1, 2025 to Sep 4, 2026Model Insight
With persistence 0.991, volatility shocks have a half-life of 80 trading days (~0.3 years), close to a unit root, so long-run forecasts are highly sensitive to this estimate. Returns follow a Student-t distribution with v = 7.58 degrees of freedom, capturing fatter tails than a normal distribution.
