Screening Chinese Stocks by Turnover, Market Cap, Profitability, and PE

Summary

This note outlines a Chinese A-share stock screen combining turnover, company size, positive earnings, and a positive price-to-earnings ratio. It describes selecting stocks with turnover in a specified band, market capitalization below a stated ceiling, no reported losses, and PE above zero. A formula-style condition and a Python example are offered as implementation references, although the Python checks do not consistently match the written conditions.

The author acknowledges that valuation and a few trading filters alone do not assess a company's full financial condition, growth prospects, competitive position, or market environment. The suggested improvement is to incorporate those broader fundamentals and market factors. No backtest, return series, or evidence of risk-adjusted performance is provided, so the screen should be treated as a rough selection rule rather than a validated investment strategy. Data periods and implementation details would need careful review before use.

Key ideas

• The proposed screen combines turnover, market capitalization, profitability, and positive PE conditions.
• The note provides both a formula reference and a Python implementation example.
• The implementation example contains conditions that may not faithfully implement the written screen.
• The author recommends adding measures of earnings quality, growth, operations, and competitive position.
• No empirical performance evidence is presented.
