Intraday A-Share Limit-Up Screening with Turnover and Stock Exclusions

Summary

The post outlines a short-term Chinese equity selection approach that filters for turnover between 3% and 12%, excludes Beijing-listed and ST-designated stocks, and seeks candidates before 10 a.m. It frames the method as a five-step limit-up trading technique, emphasizing early identification of stocks that may reach the daily price limit. A code example instead checks for a daily percentage change of at least 9.5%, alongside the exclusions.

The description does not explain the five steps in detail, reconcile the early selection time with the daily data used in the example, or provide backtest results. It warns that reliance on technical signals in volatile stocks makes the approach vulnerable to market sentiment and that the restrictive style may miss other opportunities. The author suggests adding fundamental analysis and adjusting selection timing and limit-up criteria to market conditions. The material is an incomplete screening sketch, not validated evidence of returns.

Key ideas

• The proposed screen uses a 3% to 12% turnover range and excludes Beijing listings and ST stocks.
• It aims to identify potential limit-up candidates before 10 a.m.
• The example code selects stocks with a daily gain of at least 9.5%, but does not implement the stated turnover filter.
• The post gives no backtest evidence and does not define the five-step method.
• It identifies sentiment exposure and narrow style selection as risks.
