A-Share Stock Screen Using Turnover, a Fresh KDJ Cross, and Opening Gain

Summary

This stock selection rule screens Chinese equities for turnover between 3% and 12%, a newly formed bullish KDJ crossover, and a price gain below 6% at the 9:25 observation. The accompanying explanation presents turnover and the technical signal as ways to identify active stocks with upward momentum, while the opening-price filter is intended to avoid names that have already risen sharply.

The post includes example indicator logic and a Python implementation, though the implementation adds conditions such as price above its 20-day moving average and a market capitalization threshold. It provides no performance results or backtest evidence, so the screen's effectiveness cannot be assessed from the document. The author cautions that technical filters may overlook earnings and profitability, and that the 9:25 price move can reflect temporary sentiment. Suggested extensions include adding fundamental, volume-price, and sentiment measures; any version would require careful validation and attention to execution timing.

Key ideas

• The core screen combines a 3%–12% turnover range, a fresh bullish KDJ crossover, and a gain below 6% at 9:25.
• The stated rationale is to find active stocks that have not already made a large early price move.
• The sample implementation includes extra filters, including price above its 20-day average and a capitalization threshold.
• The document gives no backtest or outcome data to establish the screen's performance.
• Technical signals and the early price observation may miss fundamental risks or reflect temporary sentiment.
