Screening Chinese Stocks by Range, Large-Order Flow, and Auction Value

Summary

The proposed stock screen selects shares whose daily range exceeds a threshold and whose large-order net volume remains positive for at least three consecutive days. It then ranks candidates by the day’s auction amount and keeps the five highest-ranked stocks. The stated rationale is to focus on active shares and potentially capture market attention. The article also suggests adding fundamental filters, including positive earnings per share and a return on equity threshold, and recommends considering business fundamentals and the macro outlook.

The article warns that activity-based criteria may overlook company fundamentals and broader economic conditions, making the screen risky. It provides no backtest, return series, benchmark comparison, or evidence that the ranking predicts future performance. Its Python reference should be treated cautiously: the range filter shown does not clearly implement the described amplitude threshold, and its rolling volume calculation is not an explicit test for three consecutive qualifying days. The proposed screen is therefore a stated selection idea, not a validated strategy.

Key ideas

• The screen selects stocks by daily range and sustained positive large-order net volume.
• It ranks qualifying stocks by auction amount and selects the top five.
• Fundamental measures and macro analysis are suggested as possible additional filters.
• The article warns that short-term activity measures omit important sources of risk.
• The code example may not implement the stated range and consecutive-day rules as described.
