Screening Stocks by Turnover, Three Falling Sessions, and Five-Year ROE

Summary

This Chinese equity screening strategy selects stocks with turnover between 3% and 12%, three consecutive declining sessions, and return on equity above 15% for five consecutive years. The article presents the ROE filter as a way to favor firms with sustained profitability and adds turnover as a measure of trading activity. Its suggested refinements include considering other financial measures and broader market conditions.

The document includes indicator and Python implementation examples, but supplies no historical performance results or evidence of profitability. It acknowledges that the screen omits company-specific financial risks and macroeconomic conditions. The examples also differ in how they operationalize the stated rules: one checks a moving-average decline, while another uses recent closing prices and includes a turnover-like calculation based on price change. These discrepancies make careful validation necessary before relying on either implementation.

Key ideas

• The proposed screen combines turnover within a specified band, three declining sessions, and five years of ROE above a threshold.
• The article presents sustained ROE as a signal of profitability, while turnover bounds trading activity.
• Suggested refinements include adding other financial measures and adapting to market conditions.
• The examples do not implement every rule consistently, so their outputs may differ from the stated screen.
• No backtest evidence is provided, and the article notes that financial and macro risks are omitted.
