Screening Shanghai-Listed Stocks by Turnover and Relative Trading Volume

Summary

This Chinese equity screen selects stocks whose codes begin with the Shanghai prefix, with turnover between 3% and 12% and a volume ratio between 1.5 and 6. The rationale is to seek shares with meaningful trading activity and market attention without selecting exceptionally high relative volume. The document includes an example that filters daily stock data and then sorts qualifying names by market value.

The note does not report a backtest, returns, or evidence that these thresholds improve selection. It warns that the rules omit company fundamentals and may miss worthwhile stocks with lower volume ratios. Suggested extensions include valuation and other fundamental measures, additional technical indicators, and adapting criteria to industry or market conditions. The stated thresholds are a screening heuristic; the document provides no validation of their predictive value.

Key ideas

• The screen combines a Shanghai stock-code prefix with turnover and relative-volume thresholds.
• The proposed rationale is to find active stocks without extremely elevated relative volume.
• The example ranks selected stocks by market value after applying the filters.
• The method omits fundamentals and may exclude attractive stocks that fail its volume conditions.
• No performance evidence is provided for the thresholds.
