Screening Chinese Stocks by Daily Range and Profit Growth

Summary

This stock screen combines a daily price-range condition with a market-segment filter and annual earnings growth. It selects shares whose high-to-low range exceeds one percent of the prior close, whose codes begin with 60, and whose parent-company net profit growth is above 20% and no higher than 100%. The document gives both a platform indicator formula and a Python-style example of applying those filters to stock data.

The post interprets the range condition as a sign of higher volatility and the earnings filter as evidence of business growth, then cautions that technical and financial measures alone may not capture investment value or risk. It suggests adding further indicators or using a multifactor screen. No backtest, return series, benchmark, or selection-date procedure is supplied, so the screen's predictive value and survivorship or data-timing effects cannot be assessed from the document.

Key ideas

• The screen requires a daily high-low range greater than one percent of the previous close.
• It restricts eligible shares to codes beginning with 60.
• It selects parent-company net profit growth above 20% and at most 100%.
• The post warns that a few technical and financial conditions may give an incomplete view of risk and value.
• No backtest or performance evidence is presented.
