Chinese Stock Screening by Turnover, Float Value, and Main-Force Control

Summary

The document describes a Chinese main-board stock screen that combines a turnover-rate band, a circulating market-value band, and a measure of yesterday’s main-force control. It presents the same basic filters in prose and as example indicator and Python implementations. The proposed rationale is to focus on stocks with current short-term interest rather than selecting by past limit-up counts.

The document offers no backtest, performance data, or evidence that main-force control predicts subsequent returns. It acknowledges that the screen relies on a single, potentially noisy signal and leaves out company fundamentals and sector themes. It suggests adding those factors and using further measures of large-player flows or intraday price patterns. The provided rule and code should be treated as illustrative: the prose specifies a comparison between yesterday’s closing price and a control measure, whose interpretation and data definition are not established in the article.

Key ideas

• The screen targets main-board shares within specified turnover and circulating-value ranges.
• It adds yesterday’s main-force control as the selection signal.
• The document argues that this may reflect current short-term opportunities more directly than historical limit-up counts.
• It warns that the signal alone may misclassify stocks and does not incorporate fundamentals or sector conditions.
• The author suggests combining the control measure with company, industry, flow, or intraday information.
