Screening Chinese Stocks by Price Range, Trading Value, and Turnover

Summary

This A-share stock screen combines three activity filters: daily price range above 1%, previous-day trading value above 60 million, and previous-day turnover above 8%. The article argues that higher turnover may identify actively traded, liquid stocks that can move quickly, while acknowledging that the screen focuses heavily on short-term price behavior and past trends.

It includes example formulas and Python snippets for applying the conditions, but provides no backtest results or evidence that the screen predicts returns. The examples also contain implementation details that may not align cleanly with the stated timing of the filters. The article suggests adding valuation and profitability measures, such as price-to-earnings and ROE, and using price-trend analysis to broaden the selection criteria. The screen is therefore a basic selection rule, not a demonstrated standalone strategy.

Key ideas

• The screen requires a daily range above 1%, previous-day trading value above 60 million, and previous-day turnover above 8%.
• High turnover is treated as a sign of active trading and potentially better liquidity.
• The article warns that focusing on short-term activity and prior trends may miss other opportunities.
• It proposes adding fundamental measures and price-trend analysis to make the screen more comprehensive.
