Screening Chinese A-Shares by Daily Range and Revenue Growth

Summary

This stock screen combines a daily high-low range greater than one percent of the previous close, a code beginning with 60, and revenue growth: 2021 revenue must exceed 2018 revenue by more than a stated threshold. The final version also requires market capitalization of at least 1 billion yuan. The article explains the range filter as selecting more volatile stocks, the code prefix as narrowing the market segment, and revenue growth as a basic growth criterion. It gives example formulas for a screening platform and a Python-style workflow.

The post offers a simple screening recipe rather than a tested trading strategy. It reports no backtest, portfolio returns, or evidence that the selected conditions predict future performance. It cautions that comparing revenue across only two years gives an incomplete picture of business health, and that high-range stocks may carry greater risk. It suggests considering several years of revenue data and adding financial or operating measures. The code examples are implementation references and may require adjustment to match data fields and platform conventions.

Key ideas

• The screen requires a daily high-low range above one percent of the previous close.
• It restricts candidates to stocks whose codes begin with 60.
• Revenue in 2021 must be more than 1.1 times revenue in 2018.
• The final selection also sets a minimum market capitalization of 1 billion yuan.
• The post warns that a two-year revenue comparison is incomplete and that high volatility increases risk.
