Dec 15, 2016 to Aug 21, 2026Model Insight
The estimated Student-t degrees of freedom v = 2.08 sit at the infinite-variance boundary (v → 2): the model is attributing extreme moves to heavy tails rather than to volatility, so the volatility scale is unreliable here. See the boundary-parameters flag.
