A-Share Screening with Turnover, a Fresh KDJ Cross, and Float Size

Summary

This note describes an A-share stock screen combining daily turnover between 3% and 12%, a newly formed KDJ golden cross, and a tradable share count no greater than 5.5 billion. Its rationale is to pair trading activity and a technical momentum signal with a float-size constraint. The indicator reference also includes a close above the 20-day moving average, while the written headline logic does not, leaving the intended screen somewhat inconsistent.

The article provides formula and Python examples, but the Python logic checks a recent KDJ value increase rather than explicitly detecting a crossover, and uses a turnover quantile condition that differs from the stated current turnover range. It reports no backtest results or evidence of performance. The author notes that technical and sentiment-based selection omits company fundamentals, valuation, and risk assessment, and recommends adding fundamental measures and considering market and sector conditions. The float-size threshold is presented as a screening choice requiring further validation.

Key ideas

• The stated screen selects stocks with turnover from 3% to 12%, a recent KDJ golden cross, and a float of at most 5.5 billion shares.
• The indicator formula adds a close-above-20-day-average condition that is absent from the verbal summary.
• The Python example uses proxies for turnover and KDJ conditions that do not exactly match the stated rules.
• The document provides no performance results and warns that technical signals omit fundamental and valuation risks.
