Stock Screening by Price Range, Limit-Ups, and Auction Net Buying

Summary

This Chinese stock-screening strategy combines three conditions: daily amplitude above 1%, at least two limit-up events during the prior 500 days, and positive net buying attributed to major investors during the opening auction. It also proposes ranking candidates using amplitude, limit-up frequency, and auction buying. The article supplies example indicator rules and a Python sketch, but these implementations use different data and calculations, so they should not be assumed to match exactly.

The rationale is that price movement, repeated limit-ups, and buying pressure may help identify active stocks with upward potential. The article provides no backtest, performance figures, or validation evidence. It warns that the screen focuses on technical and flow signals and omits company finances and valuation; it recommends further fundamental and industry research, additional screening factors, and risk controls. The method is therefore a candidate-generation idea, not a complete investment process, and its signals do not ensure future gains.

Key ideas

• The screen requires amplitude above 1%, at least two limit-up events in 500 days, and positive opening-auction net buying.
• The article suggests ranking candidates using amplitude, limit-up count, and auction buying.
• It offers example indicator rules and a Python sketch whose data handling and calculations may differ.
• The screen omits fundamental and valuation analysis and has no reported performance validation.
• Further research and risk controls are recommended before trading candidates.
