Screening Chinese Stocks by Volatility, Profitability, Size, and Institutional Flows

Summary

This document describes a stock screen for Chinese equities that combines daily price range, market capitalization, profitability, and institutional trading activity. It selects companies with an intraday range of at least 1%, market capitalization no greater than 10 billion yuan, positive net profit, and positive net institutional buying. The stated rationale is to find active smaller companies with positive earnings and signs of institutional interest.

The article offers indicator and Python examples, then suggests adding technical measures and industry research. It cautions that an emphasis on short-term volatility may overlook longer-term trends, that single indicators provide an incomplete picture, and that institutional flows do not capture individual investor activity. It gives no backtest, performance results, or evidence that the criteria predict returns. The code examples are presented as references, and the article recommends checking historical effectiveness and combining the screen with fundamental analysis and risk controls.
