Screening Chinese Stocks by Price Range, ROE Persistence, and Popularity
Summary
This Chinese-language post proposes a stock screen combining a daily high-low range of at least one price unit, return on equity above 15% for five consecutive years, and ranking by stock popularity. The stated rationale is to find shares with notable price movement and a record of profitability, then prioritize names attracting market attention. The post also suggests reducing the influence of popularity and considering safety margin, trading volume, financial information, and announcements.
It identifies several limitations: popularity may reflect sentiment rather than value, rankings can amplify risky crowd behavior, and popularity measures may differ across data providers. The document includes example formulas and Python-style selection logic, but reports no backtest, returns, or evidence that the combined screen outperforms a benchmark. Its examples also leave implementation details of the popularity score and financial data handling unclear. The screen is best understood as a proposed equity-selection heuristic, not a validated trading strategy.
Key ideas
- The proposed screen requires a high-low price range of at least one unit and five years of ROE above 15%.
- It ranks qualifying stocks by popularity, while recommending that this factor receive less weight.
- The author identifies sentiment, ranking methodology, and data-provider differences as sources of risk.
- Additional fundamental and trading-liquidity measures are suggested, but no evaluation results are provided.
