A-Share Stock Screen Using Turnover, KDJ Growth, and Board Exclusion

Summary

This note describes a Chinese A-share screening rule that selects stocks with turnover between 3% and 12%, a rising KDJ K value, and no listing on the STAR Market. It suggests combining these conditions with market trends and hot themes, and frames the board exclusion as a way to avoid some technology-stock risk. A formula and a Python example illustrate the filters; the Python example uses average turnover and compares the latest two KDJ values.

The note provides no backtest, sample period, performance figures, or evidence that the screen predicts gains. It also cautions that technical indicators can generate false breakouts or overfit, and that board classification alone does not capture a stock’s risk. The selection rule is therefore a preliminary filter rather than a complete strategy. The turnover boundary wording varies slightly between the prose and code examples, so implementation details should be checked before use.

Key ideas

• The screen requires turnover between 3% and 12% and a rising KDJ K value.
• It excludes stocks classified as belonging to the STAR Market.
• The note recommends considering market trends and themes alongside the technical filters.
• It warns that indicator-based selection can produce false signals and overfitting.
• No backtest or evidence of investment performance is provided.
