Model Insight

This asset shows asymmetric liquidity dynamics: illiquidity rises 235% more after negative returns than after positive returns of equal magnitude. This multi-frequency model splits illiquidity into a fast short-run component and a slow-moving long-run level that drifts over the sample rather than a constant baseline.
