Parameter Estimates

Jun 29, 2016 to Oct 23, 2026

Model Insight

With persistence 0.999, volatility shocks have a half-life of 656 trading days (~2.6 years), close to a unit root, so long-run forecasts are highly sensitive to this estimate. Returns follow a Student-t distribution with v = 4.55 degrees of freedom, capturing fatter tails than a normal distribution.
