Screening Chinese Stocks by Daily Range, Industry, and Market Value

Summary

This stock-screening idea combines four conditions: daily high-low range greater than 1% of the previous close, a code beginning with 60, a beverage-alcohol industry classification, and market value of at least 1 billion yuan. The article interprets the range filter as selecting more volatile stocks and the code prefix as restricting the market universe. It suggests that industry exposure may reflect a company’s business characteristics, while also acknowledging that policy and market conditions can affect an industry.

The article offers example formula and Python implementations, but does not report a backtest, portfolio returns, or risk-adjusted results. Its Python sample appears inconsistent with the stated screen: the industry lookup names a different sector, and its market-value calculation depends on data fields whose sourcing and meaning are not established in the text. The proposed conditions are screening criteria, not evidence of investment value. The article itself recommends combining technical and fundamental factors and cautions that a single indicator cannot capture a stock’s full risks.

Key ideas

• The screen selects stocks with a daily high-low range above 1% of the previous close.
• It restricts candidates to codes beginning with 60 and a beverage-alcohol industry classification.
• The stated final screen adds a minimum market value of 1 billion yuan.
• The article acknowledges policy and market risks and recommends considering additional factors.
• The Python example contains apparent mismatches in its industry lookup and market-value data inputs.
