Screening Chinese Stocks by Turnover, Market Capitalization, and Profitability

Summary

The article outlines a short-term A-share stock screen based on turnover and company size. It seeks stocks with turnover between 3% and 12%, market capitalization below 10 billion yuan, no reported losses, and previous-day turnover above 8%. The document also includes sample formula and Python-style implementation material, though the examples do not fully align with the stated rule: the formula uses a market-cap comparison that appears inconsistent with the ceiling, and the code uses a single historical date range rather than a live, point-in-time process.

The article says that relying mainly on recent trading activity can expose the strategy to volatility and speculative price moves, and that a single day’s turnover may not persist. It proposes adding technical measures and fundamental factors such as earnings growth or valuation. No backtest, portfolio construction method, or performance evidence is supplied, and the suggested improvements are not specified as a tested final rule.

Key ideas

• The screen combines a 3%–12% turnover band with previous-day turnover above 8%.
• It also requires market capitalization below 10 billion yuan and excludes loss-making companies.
• The article warns that one-day trading activity may be unstable and can overlook fundamentals.
• It suggests adding technical and fundamental filters but reports no tested results.
• The sample implementations contain apparent mismatches with the stated market-cap condition and timing.
