Screening Chinese A-Shares by Turnover and a Fresh KDJ Crossover

Summary

This stock screen selects A-shares with turnover between 3% and 12%, a newly formed KDJ golden cross, and an exclusion for Beijing-listed shares. The rationale combines a trading-activity filter with a technical timing signal, while the geographic exclusion is presented as an attempt to reduce exposure to policy effects. The document gives both a formula reference and a Python example for applying the conditions to daily market data.

The page does not report a backtest or measured returns. It acknowledges that the screen omits company fundamentals and that excluding one region may not adequately control policy risk; it suggests adding valuation, profitability, volatility, and broader policy-related measures. The sample implementation’s KDJ check compares recent values, so readers should confirm that it faithfully identifies a newly formed crossover before relying on it. The stated conditions describe a candidate-selection screen, not a complete portfolio or exit strategy.

Key ideas

• The screen filters for A-share turnover from 3% to 12% and a recent KDJ golden cross.
• It excludes shares identified as belonging to Beijing.
• The stated approach does not include fundamental analysis or a complete risk-control framework.
• No backtest results are supplied, and the implementation should be checked against the intended crossover condition.
