Chinese Stock Screen Using Turnover, Float, and Prior-Day Activity

Summary

This proposed Chinese equity screen selects stocks with current turnover between 3% and 12%, circulating shares capped at 5.5 billion, and prior-day turnover above 8%. The formula and Python example add a circulating market-value threshold above 10 billion yuan. The article presents these conditions as a way to combine liquidity with recent trading activity and suggests extending the screen with measures such as profit growth or capital flows.

The document offers no backtest, candidate list, or performance statistics, so it does not show whether the filters produce useful returns. Its final description and examples include a market-value threshold not present in the opening summary, which makes the intended specification ambiguous. The article itself cautions that the screen emphasizes technical and market-activity measures while using few fundamental criteria, limiting its value as a measure of company quality or long-term prospects. The threshold definitions and data units would need to be checked before reproducing the screen.

Key ideas

• The proposed screen uses current turnover, circulating shares, and prior-day turnover.
• The formula and code also require circulating market value above 10 billion yuan.
• The opening description omits the market-value condition, leaving the intended screen unclear.
• The article provides no backtest or performance evidence.
• It recommends adding fundamental, volume, and capital-flow measures while recognizing the limits of activity-based filters.
