Screening Chinese Stocks by Volatility, Turnover, and Money Flow
Summary
This document presents a Chinese equity screening rule that selects stocks with daily amplitude above 1, turnover between 2% and 9%, and stronger capital flow. Its rationale is to combine price movement and trading activity with an estimate of buying pressure, seeking shares attracting active market interest. Formula and Python examples illustrate related calculations, including comparisons of price to average price and a flow-strength measure.
The author notes that this is a simple, short-term screen and does not account for company finances, governance, or industry conditions. The examples also do not establish profitability or provide backtest evidence, and the Python sample adds a financial yield filter beyond the headline rule. Suggested refinements include adding valuation and trend indicators, considering business quality and industry prospects, and controlling turnover and concentration through risk and position management.
