Oct 4, 2016 to Jul 31, 2026Model Insight
Estimated persistence of 1.000 is at or above 1 (non-stationary): illiquidity shocks do not decay and the long-run level is undefined, so long-horizon forecasts should be treated with caution.
Asymmetry: illiquidity responds almost entirely to negative returns
