Chinese Stock Screen Using Turnover, Float Value, and Institutional Buying

Summary

This proposed screen selects main-board Chinese stocks with turnover between 3% and 12%, a circulating market value between 5 billion and 10 billion yuan, and a newer reported institutional ownership figure above an older one. The article treats that ownership increase as a possible sign of institutional buying, combined with liquidity and company-size filters. It gives both a formula-style specification and a Python example for filtering a supplied dataset.

The article offers a rationale and suggested refinements, not evidence that the screen earns positive returns. It cautions that institutional purchases can be followed by selling, and that the limited filters omit other technical and fundamental conditions. It suggests considering valuation measures such as price-to-earnings, PEG, and price-to-book ratios, and examining institutional holding size and duration more closely. The screen does not define the reporting intervals behind the two ownership readings, portfolio construction, rebalance timing, transaction costs, or risk controls, so those details would need to be settled before testing or implementation.

Key ideas

• The screen filters main-board stocks by turnover, circulating market value, and increasing institutional ownership.
• The stated turnover range is 3% to 12%, and the circulating value range is 5 billion to 10 billion yuan.
• The article provides formula and Python examples for applying the filters.
• It warns that institutional buying can be an unreliable signal and that the screen omits other relevant factors.
• Suggested refinements include valuation measures and closer analysis of institutional holding duration and size.
