Chinese Stock Screen: Turnover, Three Declining Sessions, and Concentration

Summary

The article describes a Chinese equity screening rule that selects stocks with turnover between 3% and 12%, three consecutive declining sessions, and concentration below 20%. It presents the decline pattern as a technical condition and describes the concentration and turnover thresholds as additional filters. The article also includes example formula and Python implementations intended to identify candidates, with code that ranks qualifying stocks by capitalization.

The author cautions that the screen is subjective and may overlook company fundamentals, industry characteristics, and high-growth opportunities. Suggested improvements include combining fundamental, technical, and industry measures into a composite score and applying stop-loss and take-profit rules. No backtest methodology or measured performance is supplied, so the document does not establish that the screening conditions predict returns. The included examples also rely on particular data fields and platform conventions; their calculations should be checked against the intended definitions of concentration, turnover, and a declining session before use.

Key ideas

• The screen requires turnover between 3% and 12%, three consecutive declining sessions, and concentration below 20%.
• The article provides example implementations for selecting and ranking candidate stocks.
• The author identifies missing fundamental and industry analysis as limitations.
• A composite score and explicit exit rules are suggested as possible improvements.
• No measured backtest results are provided to validate the screen.
