Chinese Small-Cap Stock Screen Using Range, Size, and Profitability

Summary

This Chinese equity screen combines daily amplitude above a threshold with limits on freely tradable shares and total market capitalization, then requires the company to be profitable. The rationale is to find relatively small companies with active price movement and no reported losses. The example code further ranks qualifying names by turnover and selects a portion of the universe, though the article does not explain why turnover is the preferred ranking measure.

The note warns that smaller companies can carry greater market risk, that sharp market or sector changes may undermine the screen, and that amplitude itself can signal risk as well as opportunity. It recommends combining the screen with fundamental and technical analysis, diversifying across holdings, and considering market conditions. No backtest or return evidence is supplied, and the article gives limited detail on data definitions and portfolio construction, so the rules remain a basic screening proposal rather than a validated strategy.

Key ideas

• The screen requires elevated daily amplitude, a cap on free float and market capitalization, and positive profitability.
• The stated rationale is to identify smaller companies with active trading and no losses.
• The example ranks qualifying stocks by turnover, but does not justify that ranking choice.
• The article flags small-company and market risks and recommends diversification and broader analysis.
• No backtest or performance evidence is provided.
