Stock Screening by Turnover, Daily Gains, Board Type, and Positive P/E

Summary

This Chinese equity screen looks for non-ST main-board stocks with turnover between 3% and 12%, a daily gain greater than 1%, and a positive price-to-earnings ratio. The activity and price conditions aim to identify shares with market participation and positive short-term movement, while positive P/E excludes companies with negative earnings under the relevant data convention. The article proposes adding measures such as PEG, price-to-book, revenue growth, and capital flows to broaden the assessment.

It provides formula and Python references, but neither is a complete, demonstrated implementation of every stated requirement: the formula does not explicitly show the turnover band or daily return threshold, and the Python sample checks whether “ST” appears in a code rather than clearly using the listed stock-type fields. The article reports no backtest, portfolio construction, or returns evidence. It also acknowledges that P/E alone does not measure earnings quality or determine whether a stock is undervalued, and that sentiment and policy can affect prices. The rules are a simple screening proposal, not evidence of investment value.

Key ideas

• The screen combines turnover in a specified band, a positive daily move, main-board non-ST status, and positive P/E.
• Turnover and daily gains serve as market activity and price-movement filters.
• The author suggests adding valuation, growth, and capital-flow measures for broader analysis.
• P/E alone does not capture earnings quality or establish that a share is undervalued.
• The code examples do not clearly implement all written conditions, and no results are reported.
