A Chinese Equity Screen Using Turnover, Robotics Exposure, Size, and Concentration

Summary

This Chinese A-share stock screen combines daily turnover between 3% and 12%, membership in a robotics concept group, float market value below a stated ceiling, and a shareholder concentration condition. The proposed rationale is to find actively traded smaller companies while excluding stocks considered too concentrated. The article also suggests combining valuation, growth, competitive strength, and financial stability when refining the screen.

The post supplies formula and Python examples, but its concentration condition is internally inconsistent: it names a “70<20%” measure while the sample filters shareholder ratios to be both below 20% and at least 70%, which cannot both hold. The sample also relies on particular data fields and dates, and does not provide performance results or a backtest. Its warning that a single major shareholder can distort concentration measurements is relevant, but the proposed screen should not be treated as validated evidence of returns or risk reduction.

Key ideas

• The screen combines turnover, robotics concept membership, float market value, and a shareholder concentration filter.
• The stated concentration threshold conflicts with the sample code’s simultaneous below-20% and at-least-70% conditions.
• The article proposes adding valuation, growth, competitive, and financial stability measures.
• A major shareholder’s holdings can materially affect a concentration metric.
• No backtest or performance evidence is provided.
