Trade Count Refinements to a Chinese Equity Reversal Factor

Summary

This study examines whether the number of executions recorded in tick data can improve a conventional reversal factor for Chinese A-share equities. It divides the traditional factor using trade-count information and proposes a refined reversal signal. The summary reports mean IC of -0.057 and mean rank IC of -0.070, with well-ordered quintile performance and a long portfolio distinct from the other groups.

The reported long-short portfolio has 19.3% annualized return, 7.68% annualized volatility, a 74.3% monthly win rate, and an information ratio of 2.51; controlling for Barra style and industry effects raises the reported information ratio to 2.97. These are claims from the document summary, which provides no details on sample period, transaction costs, portfolio construction, or robustness checks. The results therefore describe the study's reported evidence, not a guarantee of future performance.

Key ideas

• Tick-level trade counts can be used to refine a conventional equity reversal factor.
• The study reports negative mean IC and rank IC for its proposed signal.
• Its reported quintile portfolios are ordered, with the long group separated from the others.
• The reported long-short information ratio improves after controlling for style and industry factors.
