A-Share Screening with Turnover, KDJ Crossovers, and Liquidity
Summary
This article describes an A-share stock screen combining turnover, a newly formed KDJ golden cross, and the prior day's actual turnover. Its final rule also requires market capitalization above one billion yuan, current turnover between 3% and 12%, and prior-day turnover above 3% and no more than 28%. The proposed rationale is to favor liquid shares showing an upward technical signal and recent trading activity.
The article discusses limitations: turnover does not account for company size or trading volume, prior-day activity is only a limited measure of recent interest, and the screen omits fundamentals and broader economic conditions. It suggests adding earnings growth, market sentiment measures, and average volume or market capitalization checks. A formula reference and Python example are included, but the code's data fields and indicator calculations are not validated in the text, and no backtest results are provided.
Key ideas
- The screen combines current turnover bounds with a newly formed KDJ golden cross.
- It requires prior-day actual turnover to fall within a stated range and market capitalization to exceed one billion yuan.
- The article presents liquidity, technical momentum, and recent activity as the selection rationale.
- It warns that the rules omit fundamentals and macroeconomic context and that turnover alone has limitations.
- It proposes adding fundamental, sentiment, and liquidity measures for further evaluation.
