Chinese Stock Screening with Turnover, Profit Growth, and Bollinger Bands

Summary

This document describes a Chinese equity screen combining turnover, year-over-year net profit growth attributable to parent-company shareholders, and price position relative to Bollinger Bands. It selects stocks with turnover from 3% to 12%, profit growth above 20% and no more than 100%, and closing prices between the Bollinger middle and upper bands. The accompanying examples show platform-specific screening logic and a Python workflow using Baostock data and a 20-period Bollinger calculation.

The article frames the screen as a way to combine trading activity, company earnings growth, and a technical trend condition. It gives no backtest results or performance evidence. The author notes that the filter omits other financial and industry factors, and that technical indicators can produce misleading signals; the sample Python implementation also uses a specific historical profit-data period, which limits its direct applicability as a current selection method.

Key ideas

• The screen requires turnover between 3% and 12%.
• It selects year-over-year parent-attributable net profit growth above 20% and at or below 100%.
• The price condition places the close between the Bollinger middle and upper bands.
• The article warns that omitted fundamentals and temporary technical signals can create blind spots.
