Vitura SA Asymmetric ILLIQ Liquidity Analysis

High-persistence model: shocks decay very slowly, so the theoretical long-run value may not be practically meaningful

Model 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 rises 150% more after negative returns
