Mainland China Stock Screening with Turnover, Gains, and Volume Ratio

Summary

This stock screen selects main-board shares with turnover between 3% and 12%, a daily gain above 1%, and a volume ratio between 1.5 and 6. The article presents the combination as a way to find shares with active trading while limiting the screen to a defined range of turnover and relative volume. It includes example formula and Python-style selection logic, though implementation details vary across the examples.

The document offers no backtest results or evidence that the criteria predict returns. It cautions that technical filters can admit noisy candidates, that the volume-ratio range may exclude otherwise relevant shares, and that volatile, high-turnover stocks may be misclassified as attractive short-term candidates. It suggests combining the screen with fundamental measures such as valuation ratios or with relative-strength indicators. These are screening criteria rather than a complete trading system: the article does not specify portfolio construction, entry and exit rules, or risk controls.

Key ideas

• The screen requires main-board stocks to meet specified turnover, daily return, and volume-ratio ranges.
• The volume-ratio filter is intended to capture trading activity alongside price movement.
• The article supplies example implementations but reports no performance testing.
• The author notes that narrow filters and noisy technical signals can exclude or misclassify stocks.
• Fundamental measures and relative strength are suggested as possible additions.
