Chinese Stock Screen Combining Price Range, ROE, and Buying Activity

Summary

This Chinese equity screen combines three conditions: daily price range above a volatility benchmark, return on equity above 15% for five consecutive years, and a measure of current buying activity above 5%. The intended logic blends price movement, sustained profitability, and signs of active trading. The page includes formula and sample code references for applying the filters.

The author notes that the screen may omit other important fundamentals, that past data may not predict future price moves, and that buying-activity measures can reflect institutional trading behavior. Suggested improvements include adding debt and revenue-growth measures, valuation or volume data, and broader validation. No backtest results or evidence of profitability are supplied, and the stated formula implementations should be checked against the intended definitions before use.

Key ideas

• The screen requires a price range exceeding an ATR-based threshold.
• It selects companies with ROE above 15% for five consecutive years.
• A buying-activity measure must exceed 5% on the current day.
• The rules combine technical, fundamental, and trading-activity filters.
• The page gives no performance evidence and warns that historical filters can fail.
