A Stock Screen for Turnover and Recent Limit-Up Activity

Summary

The document describes a short-term Chinese stock screen: select shares with turnover between 3% and 12%, an initial listing year of 2021, and more than two limit-up sessions during the latest ten-day window. The stated rationale is that moderate turnover and repeated sharp gains may identify stocks with strong recent price action. The post also suggests adding quantitative and qualitative company measures and considering fundamentals and valuation before acting.

The article warns that the screen emphasizes price rises and can miss business quality and value, while repeated limit-up moves may reflect speculative activity and invite chasing. It supplies sample Python that purports to implement the filter, but the code appears to use a proxy based on trading data and a money-flow threshold for identifying limit-ups, rather than clearly demonstrating the stated ten-day limit-up count. No backtest, performance evidence, or execution rules are provided, so the screen should be treated as an idea requiring careful data validation and independent testing.

Key ideas

• The screen combines a 3%–12% turnover range, a 2021 listing year, and more than two limit-up sessions in ten days.
• Its rationale is to find recently strong price action among stocks with moderate turnover.
• The filter omits fundamental and valuation analysis, which the article recommends adding.
• Frequent limit-up moves can signal speculation and increase the risk of buying after a sharp run.
• The sample implementation does not clearly establish that its proxy measures the stated limit-up condition, and no performance test is shown.
