A Chinese Stock Screen Combining Turnover, Order Flow, and Relative Volume

Summary

This stock-selection rule looks for turnover between three and twelve percent, an outside-volume to inside-volume ratio above 1.3, and a volume ratio between 1.5 and 6. The article frames these conditions as a way to find shares with moderate trading activity, stronger market-buying pressure, and elevated but bounded volume. It provides formula and Python examples for applying the filters to Chinese equities.

The article notes that the screen can miss attractive low-volume stocks and include heavily traded names with mediocre returns. It also points to external risks such as policy uncertainty and suggests adding price-trend or sentiment measures while adapting the screen to an investor’s style. No backtest, return analysis, or evidence establishes that these thresholds predict performance. The formula example includes additional conditions beyond the prose and does not clearly implement all stated filters in a consistent way, so its outputs may not correspond exactly to the described rule.

Key ideas

• The screen constrains turnover to a stated middle range and requires outside volume to exceed inside volume by a threshold.
• It also requires relative volume to fall within a specified interval.
• The article presents the filters as activity and order-flow criteria, not as a tested return forecast.
• Low-volume winners may be excluded, while active stocks with weak returns may still pass.
• The formula example includes extra filters and may not fully match the prose specification.
