Chinese Equity Screen Using Price Range, Turnover, and ROE

Summary

The document describes a Chinese stock screen combining a daily price-range condition, prior-day turnover within a specified band, and return on equity above 15% for five consecutive years. It presents the screen as a way to pair recent trading activity and volatility with a record of strong profitability. The accompanying discussion says that sustained high ROE may indicate profitable companies, while the trading filters identify stocks with active price movement and share turnover.

The article provides example implementations and suggests adding measures such as net profit, earnings growth, and debt ratio. It cautions that the ROE threshold may leave a narrow candidate pool and that ROE alone does not capture company quality or earning power. The examples have inconsistencies: the code does not clearly implement the stated consecutive five-year test, and its volume calculations do not transparently match the stated turnover-rate condition. No backtest or performance evidence is supplied, so the screen should be treated as a proposed selection rule rather than a validated strategy.

Key ideas

• The screen combines a price-range filter and a prior-day turnover band with a five-year ROE threshold.
• The article presents sustained high ROE as a profitability signal, but says it cannot assess company quality on its own.
• A strict ROE threshold may reduce the number of eligible stocks and limit diversification.
• The example code does not clearly match every element of the stated screening rule.
• The article recommends adding other financial measures, including profit growth and leverage.
