A-Share Screen for Low K Values, Turnover, and Two-Day Closing Highs

Summary

This A-share stock screen combines a turnover range of 3% to 12% with a KDJ K value below 20, then selects stocks whose current close is the highest close across the latest two days. The intended entry signal is thus a short-term closing-price high among stocks that meet a low-K condition and a turnover filter. The document includes formula and Python examples, and describes running the selection after screening for excluded industry codes.

The accompanying discussion characterizes the rules as a mix of liquidity and technical conditions, but supplies no backtest, return figures, or evidence that the screen improves results. It cautions that the selection omits fundamentals, industry conditions, and the broader market environment, while a two-day high may reflect noisy sentiment. It suggests adding company and market analysis. The examples also leave implementation details unclear, including how the specified day is applied to the data and whether the closing-high test is calculated consistently.

Key ideas

• The screen filters A-shares by turnover between 3% and 12% and a KDJ K value below 20.
• A qualifying stock must close at the highest level of the current and preceding day.
• The document presents the combined conditions as a short-term buy signal.
• It identifies omitted fundamentals and market context as risks, and notes that recent highs may be noisy.
• No backtest or performance evidence is provided.
