Screening Stocks by Turnover, Float Size, and Control Activity

Summary

This document outlines a Chinese stock selection rule using turnover of 3% to 12%, circulating market capitalization from 1 to 55 billion yuan, and a control activity indicator above 21. The page gives the criteria in prose and in formula-like and Python examples, making the screen straightforward to reproduce when equivalent data fields are available. The indicators combine trading activity, company float size, and a platform-defined measure of concentrated control.

The explanation suggests that combining company size with market activity can help narrow candidates, but it provides no backtest or evidence that the thresholds predict returns. It acknowledges that the control indicator may be subjective and recommends checking additional measures such as volume or MACD, along with periodic reevaluation. Data definitions, investment horizon, entry and exit rules, transaction costs, and risk controls are not specified, limiting its use to an initial screening concept.

Key ideas

• The selection rule requires turnover between 3% and 12%, a specified circulating capitalization range, and control activity above 21.
• The examples show how to express the screen in platform formula syntax and tabular data filtering.
• The control measure's interpretation may be subjective and should be corroborated with other indicators.
• No backtest, trade management rules, or performance evidence is included.
