A Chinese A-Share Screen Using Turnover and Recent Limit-Ups

Summary

The article proposes screening Chinese A-shares for turnover rates between 3% and 12%, excluding Beijing-listed stocks, and requiring at least one limit-up event in the prior 25 days. Its rationale is that recent limit-ups may indicate market attention or a catalyst, while the turnover range selects stocks with active trading. It describes a stock-selection screen rather than a complete entry-and-exit strategy, and it gives no backtest or performance evidence.

The article warns that attention around a hot stock can fade quickly and that buyers may withdraw after a limit-up. It suggests adding fundamental and industry factors, or applying machine-learning methods, to improve stability. The included code is presented as a reference, but its date filters and limit-up handling do not clearly implement the stated 25-day condition, and the article itself says additional analysis is needed. The screen therefore serves as an initial selection idea, not a validated trading rule.

Key ideas

• The proposed screen selects stocks with turnover from 3% to 12% and a limit-up during the prior 25 days.
• It excludes Beijing-listed shares and links recent limit-ups to possible market attention or catalysts.
• The article gives no evidence that the screen produces profitable returns.
• Hot-stock interest may fade, and capital may leave after a limit-up event.
• Fundamental and industry information are suggested as additional screening factors.
