A Chinese Stock Screen Using Turnover, KDJ Momentum, and Prior Limit-Up Exclusion

Summary

This Chinese-language note proposes screening stocks with turnover between 3% and 12%, a positive increase in the K value of the KDJ indicator, and no limit-up close on the previous day. It frames the prior-day exclusion as a way to avoid stocks whose recent rise may have been too rapid, while seeking candidates with continuing movement. The article includes example selection logic in a charting formula and Python, though the snippets do not present a complete, verified implementation.

The author warns that excluding prior limit-up stocks does not remove other high-volatility or high-risk names, and suggests adding technical or financial measures such as MACD or valuation ratios, as well as industry and fundamental analysis. No backtest, performance results, or validation are provided. The stated rule and code snippets also merit careful checking before use, since the prose describes an increase bounded below 100 while the examples appear to check only for an increase, and the prior limit-up condition may depend on market conventions.

Key ideas

• The screen combines turnover in a specified range with a rising KDJ K value.
• It excludes stocks that closed at the limit-up level on the prior day.
• The note presents formula and Python examples but no performance testing.
• The author cautions that the screen omits broader volatility and fundamental risks.
• The described KDJ bounds and code examples are not fully aligned and should be validated.
