Screening Chinese Stocks by Turnover and Recent Limit-Up Activity

Summary

The article describes a stock screen that looks for turnover within a stated range, at least one limit-up event during a recent lookback period, and elevated turnover on the prior day. Its rationale is to find relatively active stocks that have shown recent market attention and are trading actively again. The post also includes a code example and discusses possible extensions, such as adding company fundamentals, financial health, management, industry context, and longer observation windows.

The screen is a heuristic for activity and market heat, not a tested investment strategy. The article warns that recent high turnover can reflect short-lived speculation and that the rules omit fundamentals and longer-term price structure. It supplies no performance results or empirical validation. The example implementation also uses specific data fields and filters, so reproducing it would depend on data definitions and availability; readers should not assume that code precisely matches the verbal rules.

Key ideas

• The screen combines a turnover band with a recent limit-up event and high prior-day turnover.
• The rules aim to identify stocks with both recent attention and current trading activity.
• High turnover and limit-up activity can reflect speculation as well as sustained interest.
• The article recommends adding fundamental, industry, and longer-window measures to broaden the screen.
• No backtest or performance evidence is provided to validate the selection logic.
