Chinese Stock Screening by Price Range and Turnover

Summary

This Chinese equities screening approach selects stocks with a price range above 1%, prior-day actual turnover between 3% and 28%, and turnover between 3% and 12%. It treats price range and turnover as signs of short-term trading activity while limiting turnover to avoid stocks with potentially excessive trading costs or inefficient use of capital. The article includes example formulas and Python snippets for applying the conditions, but it does not provide a tested portfolio or a clear account of how every turnover measure is defined.

The article offers no backtest results or return evidence. It notes that the screen ignores company fundamentals and may produce volatile selections, so it cannot ensure gains. Suggested refinements include adding financial and industry information and widening turnover bounds to increase the number of candidates. Although the final description mentions stable fundamental indicators, the stated screening conditions and sample logic do not implement them. Risk controls and transaction costs are not quantified.

Key ideas

• The screen combines a price range threshold with bounds on prior-day actual turnover and current turnover.
• The turnover limits are intended to identify active stocks while avoiding excessive trading activity.
• The article supplies illustrative code but no performance evaluation.
• It warns that the conditions omit fundamental factors and may yield volatile selections.
• Fundamental data and adjusted turnover ranges are suggested as possible refinements.
