Screening Chinese Stocks by Turnover, Profit Growth, and Control
Summary
This document describes a Chinese equity screen combining daily turnover, year-over-year growth in net profit attributable to parent-company shareholders, and a “control” indicator. It selects stocks with turnover from 3% to 12%, profit growth above 20% and no more than 100%, and control above 21. The accompanying explanation treats control as the share of daily trading volume attributed to buyers and as a proxy for market sentiment.
The article provides reference formulas and Python code, but no backtest, performance evidence, or validation of the signal. It cautions that control readings can shift with market conditions and recommends considering other sentiment measures, such as capital flows and market activity. The code also illustrates implementation choices, including exclusions for some listings and use of a particular historical profit-data period, which may not match the stated screen or current data availability. The rules are therefore a screening example rather than evidence of a profitable strategy; results require independent testing and broader judgment.
Key ideas
- The screen combines turnover between 3% and 12% with profit growth above 20% and up to 100%.\nIt also requires a control reading above 21, interpreted by the article as a buyer-volume share and sentiment proxy.\nThe article supplies reference implementations but reports no backtest or strategy returns.\nControl readings may vary with market conditions, so the screen should be evaluated alongside other measures.
