Chinese Stock Screening with Auction Volume and KDJ Momentum

Summary

This Chinese stock selection post describes a screen combining price range, trading activity, and a short-term momentum signal. It selects shares with an amplitude above a threshold, a ratio based on the prior day’s turnover and the current auction volume relative to prior volume within a stated band, and a rising K value from the KDJ indicator. The author presents these inputs as a way to consider both price behavior and liquidity, then suggests adding valuation, financial, industry, and sentiment measures for a broader assessment.

The post provides no performance results or backtest evidence for the stated screen. Its illustrative Python example does not implement the described selection logic consistently: it checks market capitalization and recent consecutive price increases, while referring to data fields and filters that do not clearly match the rule. The author also notes that fixed criteria can miss stocks and that KDJ may give false signals; market volatility and sentiment are not fully captured. Treat the screen as a heuristic requiring careful implementation and independent testing.

Key ideas

• The proposed screen combines price amplitude, an auction-volume ratio adjusted by prior turnover, and a rising KDJ K value.
• The author frames activity and price movement as liquidity and technical inputs to stock selection.
• The example code does not faithfully reproduce the written screening rule, so its output should not be assumed to validate the strategy.
• The post recommends adding fundamental and sentiment measures but provides no performance evidence for the screen.
