Screening Chinese Stocks by Turnover, Recent Limit-Ups, and Volume

Summary

This article describes a Chinese A-share screen combining turnover between 3% and 12%, at least one limit-up event in the prior 25 days, current volume above 10,000 lots, and a high-open condition. It argues that moderate turnover and recent limit-ups may indicate activity and market interest, while the volume filter removes thinly traded stocks. The article also suggests adding valuation and operating measures such as price multiples and return on equity.

The article provides example indicator logic and Python-style implementation, but the examples do not fully agree on the high-open test: one checks whether the close is above the open, while the other compares the open with the prior close. It reports no backtest results or performance evidence. The screen is driven mainly by price action and sentiment, does not adequately account for company fundamentals or changing market conditions, and may select stocks based on temporary enthusiasm. The proposed fundamental additions and model adjustments are suggestions rather than tested improvements.

Key ideas

• The screen combines a 3%–12% turnover range with a limit-up event during the prior 25 days and volume above 10,000 lots.
• The article treats recent limit-ups and high opening prices as possible signs of market interest.
• It recommends adding valuation, profitability, and business-condition measures to the technical screen.
• The sample definitions of a high-open condition differ, so the intended rule needs clarification before implementation.
• No backtest evidence is provided, and sentiment-driven signals may fail in different market conditions.
