Chinese Stock Screen for Moderate Turnover and Prior Limit-Up Activity

Summary

This Chinese stock-selection note describes a screen combining turnover between 3% and 12%, at least one limit-up event in the previous 25 days, and a prior-day price condition described as a 9:15 matched price at the lower limit. It presents this as a way to identify liquid, attention-attracting shares during weak market conditions. The referenced formula ranks qualifying stocks by turnover and takes a small subset.

The note warns that the screen omits company fundamentals, may return few candidates, and may have low accuracy. It recommends combining the conditions with technical and fundamental analysis. The accompanying Python example uses market data interfaces to approximate the filters, but its field calculations do not clearly implement every stated condition; the example should therefore be treated as illustrative rather than a validated backtest. No performance results are provided.

Key ideas

• The screen combines a turnover band with recent limit-up activity and a lower-limit price condition.
• It is framed for weak market conditions and seeks shares with prior market attention.
• The source cautions that the strict filters may produce few candidates and do not assess business quality.
• It recommends adding fundamental and technical checks, but reports no strategy performance evidence.
