Sheh Fung Screws Co Ltd ILLIQ-MFMEM Liquidity Analysis

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

Model Insight

With persistence 1.000, illiquidity shocks have a half-life of 154032 trading days (~611.2 years), close to a unit root, so long-run forecasts are highly sensitive to this estimate. 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.

Asymmetry: Illiquidity rises 196% more after negative returns
