Turnover, Illiquidity, and Price-Volume Factors for China A-Shares

Summary

This research summary explores technical factors built from turnover, illiquidity, and combined price-volume information in the CSI 500 universe. It considers turnover stability, turnover variation, abnormal turnover, several illiquidity measures, On-Balance Volume, and price-volume correlation. The factors highlighted as comparatively effective include turnover stability and variation over 12 months, improved illiquidity over 12 months, negative-return illiquidity over 6 months, illiquidity variation over 3 months, and selected price-volume measures.

The report then combines six factors, including momentum, maximum interval return, turnover variation and stability, average trading value, and illiquidity variation, to improve a CSI 500 enhancement strategy. For December 2021 through February 2023, it reports higher factor returns and improvements in excess return, information ratio, and Calmar ratio versus the original approach. The summary does not provide detailed construction rules, costs, or robustness checks. Its results are historical, and the authors warn that the factors or model may stop working in future markets.
