Chinese Stock Screen Using Turnover and Control Concentration

Summary

This note outlines a Chinese equity screen that selects stocks with turnover between 3% and 12%, excludes Beijing-listed shares, and requires a measure described as today’s control concentration to exceed 21%. It argues that concentrated ownership may be associated with stronger price moves, while acknowledging that concentration can also increase manipulation risk and volatility. The post recommends considering fundamentals and technical indicators as additional filters.

A Python example is included, but it does not cleanly establish that the stated screen can be reproduced: it references a separate stock list, uses holder counts as a proxy for the control condition, and has inconsistencies in its data fields and thresholds. The article provides no backtest or evidence that the filter improves returns. Treat the listed conditions as a screening idea, not a validated strategy, and verify the data definitions before implementation.

Key ideas

• The proposed screen applies a turnover range and excludes Beijing-listed stocks.
• It adds a threshold for a measure of control concentration.
• The post links greater concentration with potential price movement but flags manipulation and volatility risks.
• The Python example uses holder data as a proxy and may not match the stated criterion.
• No performance testing is reported, and the data definitions need verification.
