A-Share Screen Using Turnover, Market Cap, Profitability, and Lower Lows

Summary

This article describes a basic A-share stock screen combining turnover, company size, profitability, and a short-term price condition. It filters for turnover between 3% and 12%, market capitalization below 10 billion yuan, positive net income, and a current-day low below the previous day’s low. It presents the conditions as a way to combine company fundamentals with a recent price decline, and includes formula and Python examples for applying the screen.

The article offers no performance test or evidence that the selected stocks earn higher returns. It cautions that price movements can reflect market sentiment and that a lower low alone does not indicate deteriorating fundamentals; it suggests considering financial and industry information alongside other indicators. The sample Python procedure checks specific historical dates and earnings data, so it does not establish a live, point-in-time screening process. The proposed filters and explanations should therefore be treated as a screening illustration, not a validated investment strategy.

Key ideas

• The screen combines turnover, market capitalization, positive earnings, and a lower daily low.
• It selects stocks with turnover from 3% to 12% and market capitalization below 10 billion yuan.
• A lower low is a price condition and does not by itself indicate a change in company fundamentals.
• The article provides screening examples but no backtest or evidence of profitability.
