Chinese Stock Screening with Auction Gains and Position Accumulation

Summary

This Chinese-language post proposes screening mainland Chinese equities using the proportion of positions added during the day and the opening auction’s price change. The stated conditions include position accumulation above 5%, an auction gain between roughly negative 2% and positive 5%, and a 9:25 gain below 6%. The post frames accumulation as a sign of buying interest and the auction move as an early price-strength measure.

It cautions that these signals alone do not establish investment value: a stock may retreat after the open or fail to extend its gains. It suggests combining them with valuation, industry and profitability information, as well as technical indicators such as moving averages and MACD. However, its explanations are internally inconsistent about the accumulation threshold, and the included code is malformed and relies on repetitive self-referential valuation comparisons. It gives no valid backtest or results, so the screen should be treated as an unverified idea rather than a demonstrated strategy.

Key ideas

• The proposed screen combines daily position accumulation with opening auction price changes.
• The stated thresholds include accumulation above 5%, an auction gain between negative 2% and positive 5%, and a 9:25 gain below 6%.
• The post warns that favorable auction behavior may be followed by a reversal or weak continuation.
• It recommends adding fundamental and technical criteria for a fuller selection process.
• The accompanying code is flawed, and no backtest evidence supports the screening idea.
