Screening Chinese Stocks by Price Range, Turnover, and Profit Growth

Summary

This proposed Chinese equity screen combines three conditions: daily price amplitude above 1, prior-day trading amount above 60 million, and year-over-year net profit growth attributable to parent-company shareholders above 20% and no more than 100%. The author presents the price movement and turnover filters as market or technical considerations, with profit growth supplying a basic fundamental filter.

The document offers an outline and sample Python logic, but no performance results or evidence that the screen has predictive value. Its code appears inconsistent with the written rules: it uses a profit data source alongside high, low, and volume fields, calculates turnover using a volume difference, and applies an absolute value to profit while filtering on profit growth. The text itself warns that profit growth can be unstable and that other company and market factors are omitted. It suggests adding more information and considering absolute profit, but does not define a tested refinement.

Key ideas

• The screen combines price amplitude, previous-day trading amount, and annual profit growth filters.
• Eligible profit growth is specified as above 20% and at most 100%.
• The document provides no backtest or evidence of returns from the selection rules.
• The sample implementation does not clearly match the stated data fields and screening conditions.
• Profit growth may be unstable, and the screen omits other company and market factors.
