Screening Shanghai-Listed Stocks by Range and Recent Limit-Ups

Summary

This Chinese equity screening idea selects stocks whose codes begin with 60, whose daily high-low range exceeds one percent of the previous close, and that have recorded more than two limit-up days within ten days. The rationale is to find Shanghai-listed shares with elevated price movement and recent rapid gains. The example also proposes sorting candidates by popularity, and outlines adding fundamental measures and profit-taking or stop-loss rules as possible refinements.

The document gives sample indicator and Python implementations, but does not provide backtest results, trade performance, or a precise definition of a limit-up day. In particular, the code examples use price comparisons as proxies for limit-up events, and the written description does not establish that those comparisons correctly account for exchange price limits or stock-specific cases. The screen targets highly active shares, so its own discussion acknowledges that volatility may complicate risk control and that a narrow focus on recent limit-ups omits other relevant information. Further validation is needed before using it as a trading strategy.

Key ideas

• The screen combines a one-percent daily range threshold with a Shanghai stock code prefix and recent limit-up activity.
• The proposed lookback window is ten days, with more than two qualifying limit-up days required.
• The rationale is to identify shares with elevated volatility and fast recent price movement.
• The author suggests adding fundamentals and explicit profit-taking or stop-loss rules.
• The code examples use price comparisons as proxies, and the document provides no validation or performance results.
