Screening Chinese Stocks with Volatility, Turnover, and KDJ Crossovers

Summary

This stock-selection approach combines three daily conditions: price amplitude of at least 1%, turnover above 2% and at most 9%, and a newly formed KDJ golden cross with the J value above 50. The document presents the combination as a way to find stocks with notable price movement and trading activity alongside a bullish technical signal. It includes indicator-formula and Python examples, though the examples do not implement the conditions identically: the Python checks the relative ordering of K, D, and J rather than directly detecting a fresh crossover.

The author cautions that the screen omits other relevant factors, including company fundamentals, and that a KDJ cross does not ensure a lasting rise. Suggested refinements include combining technical and fundamental measures and adjusting the selection timing and algorithm. No performance results or evidence of predictive value are reported, so the rules should be treated as a screening hypothesis rather than a validated strategy.

Key ideas

• The screen requires daily amplitude of at least 1%, turnover above 2% and no greater than 9%, and a KDJ crossover condition.
• The proposed rationale combines price volatility, trading activity, and a possible upward price turn.
• The Python example uses indicator ordering checks rather than explicitly testing for a newly formed crossover.
• The document reports no backtest results and warns that a KDJ signal may not persist.
• Fundamental measures and additional technical indicators are suggested as possible filters.
