A Chinese A-Share Screen Using Turnover, Ten-Day Gains, and KDJ

Summary

This stock selection approach filters Chinese equities by turnover between 3% and 12%, a positive ten-day gain below 35%, and a rising K value from the KDJ indicator. The intended logic combines trading activity and recent price movement with a short-term technical momentum signal. The document also provides formula and Python examples intended to identify qualifying stocks.

The author cautions that a single technical signal can be distorted by short-term market fluctuations and does not capture company fundamentals or broader market conditions. Suggested extensions include adding valuation, ownership, return on equity, and industry information, along with conditional entry or swing-trading rules. No backtest, benchmark, or measured performance is reported, and the code example’s data calculations may not precisely implement every stated filter.

Key ideas

• The screen requires turnover between 3% and 12% and a positive ten-day gain below 35%.
• It selects stocks whose KDJ K value is increasing.
• The method uses trading activity, recent returns, and a technical momentum measure.
• The author recommends combining the screen with fundamental and industry factors.
• No empirical results are supplied, and the example implementation may differ from the stated criteria.
