A Turnover and Price-Screening Rule for Mainland China Stocks

Summary

This article proposes a mainland China stock screen combining turnover with recent price movement. It selects stocks with turnover between 3% and 12%, a same-sector daily rise above 1%, and a stated price-change range from −5% to 2.6%. The page includes an indicator-formula reference and a Baostock Python example intended to retrieve recent daily prices and apply related filters.

The author characterizes the rule as a short-term technical screen and cautions that it omits factors such as trading volume detail and company profitability. The article suggests adding institutional capital-flow measures and adapting price thresholds to market volatility, but it does not test those ideas. Its code filters listing categories and market capitalization as additional implementation conditions, so the example is not a direct, exact reproduction of every stated screening criterion. No performance evidence is presented.

Key ideas

• The proposed screen combines turnover, same-sector daily performance, and a bounded price move.
• The turnover interval is 3% to 12%, with a stated same-sector gain threshold above 1%.
• The article presents indicator and Python references for applying related price filters.
• It warns that the screen leaves out fundamental and broader trading information.
• The proposed refinements are suggestions and are not backed by reported tests.
