Chinese Stock Screening with Revenue Growth and Profitability Filters
Summary
The document outlines a Chinese equity screening approach that starts with price amplitude, a minimum market capitalization, and a comparison of 2021 revenue with 2018 revenue. It discusses limitations of relying on revenue growth alone, including omitted profitability measures, industry differences, and changes in economic or policy conditions. It then proposes a revised screen using average return on equity over five years and ranking firms by compound annual growth.
The article includes example implementations and points to historical financial data as inputs, but it does not provide backtest results, a defined portfolio construction method, or evidence that the proposed filters improve returns. Its examples also differ from the initial screen: the final criteria replace the revenue comparison with profitability and growth ranking, and the supplied code does not cleanly match every stated criterion. These discrepancies and potential data-definition issues make the examples unsuitable as a fully specified, validated strategy without further review.
Key ideas
- The initial screen combines price amplitude and market capitalization with a multi-year revenue comparison.
- Revenue growth alone may miss profitability, industry conditions, and broader economic or policy effects.
- The proposed revision adds return on equity and ranks companies by compound annual growth.
- The article provides sample code but no performance evidence, and the implementation details do not consistently match the described rules.
