A Chinese A-Share Screen Using Turnover and Holder Concentration

Summary

This proposed Chinese A-share stock screen combines a turnover-rate band of 3% to 12%, exclusion of Beijing-listed shares, and a holder-concentration condition described as concentration below 20%. The article’s rationale is that lower concentration may indicate more evenly distributed risk, while the turnover range is intended to favor stocks with relatively stable trading activity. It also suggests adding valuation or price measures and assessing candidates by industry, earnings, and profitability.

The article supplies no backtest results or evidence that the screen predicts returns. Its sample code refers to market capitalization, float shares, exchange listings, and top-holder data, but appears inconsistent with parts of the written criteria and includes an unclear concentration calculation. The thresholds and rationale should therefore be treated as a screening proposal, not a validated strategy; data definitions, implementation, and out-of-sample behavior would need review.

Key ideas

• The proposed screen filters Chinese A-shares by turnover, listing venue, and holder concentration.
• The article argues that lower concentration may spread risk more evenly across holders.
• It proposes adding valuation, price, industry, earnings, and profitability measures.
• The document reports no performance evaluation, and its code does not clearly implement every stated condition.
