Selecting A-Shares with Turnover and a Fresh KDJ Golden Cross

Summary

This stock-selection rule screens for A-shares with turnover between 3% and 12%, a newly formed KDJ golden cross, and a positive change in the KDJ K value. The stated rationale is to favor stocks with trading activity and a bullish technical signal, with a rising K value intended to indicate strengthening price movement. The page also gives indicator-expression examples and a Python-style illustration of applying the conditions to a stock list.

The material is a screening recipe, not a tested trading system: it reports no backtest results, holding period, portfolio construction, transaction costs, or comparison benchmark. Its discussion warns that the rule omits company fundamentals and may be affected by market shifts and investor sentiment. The implementation details may not precisely match the stated rule: the example compares KDJ-related values and uses a turnover quantile, so data definitions and signal timing should be checked before relying on it.

Key ideas

• The screen requires turnover from 3% through 12%, a KDJ golden cross, and a positive change in KDJ K.
• Turnover is used as a liquidity filter, while the KDJ conditions seek an emerging bullish signal.
• The document provides formula and code examples for applying the screen to A-shares.
• It reports no evidence of profitability or details on portfolio construction and trading costs.
• The example’s calculations may differ from the stated conditions and need verification.
