Screening Chinese Stocks by Turnover, Recent Limit Ups, and Popularity
Summary
The document describes a Chinese equity screen that keeps stocks with turnover between 3% and 12% and at least one limit-up event during the previous 25 days, then ranks candidates by individual-stock popularity. It presents the rule as a way to combine liquidity, recent price strength, and market attention. The accompanying example refers to stock data and a popularity field, and sorts the selected names from highest to lowest popularity.
The article warns that popularity can concentrate risk and may distract from company fundamentals and macroeconomic conditions. It suggests retaining the turnover and recent limit-up filters while using valuation, dividend yield, or broader fundamental measures in ranking. There is no backtest, measured evidence, or precise operational definition of the popularity score. The example code also uses approximations for turnover and limit-up detection, so it should not be treated as a validated implementation of the stated screen.
