Chinese Stock Screen Using Price Range, Recent Limit-Up Gains, and Auction Turnover

Summary

This Chinese equities screening proposal selects stocks whose daily high-low range exceeds a threshold, that recorded at least one daily gain of 10% or more during the prior 25 trading days, and whose previous-day opening-auction turnover exceeds 0.26. The article presents these conditions as a way to find stocks with recent strong moves and current trading interest. Its sample indicator logic also refers to an ATR-based range check, a large prior-close-relative move, turnover, and additional filters, so the examples do not map perfectly onto the plain-language rules.

The author cautions that the screen omits company fundamentals and industry context, and that auction turnover may reflect short-lived speculative activity rather than durable interest. Suggested refinements include fundamental and industry analysis, examining turnover over a longer horizon, adding technical indicators such as MACD or RSI, and excluding limit-up or limit-down stocks. No backtest results or evidence of predictive performance are provided, and parts of the sample logic are left as placeholders. The proposal is best understood as an incomplete screening concept, not a validated strategy.

Key ideas

• The proposed screen combines a price-range condition, a recent large daily gain, and prior-day auction turnover above a stated threshold.
• The article flags missing fundamentals and industry analysis as limitations.
• Auction turnover can reflect temporary speculative attention and may not persist.
• Suggested refinements include longer-term turnover context, technical indicators, and excluding limit-bound stocks.
• The sample formulas include placeholders and are not accompanied by performance evidence.
