Screening A-Shares by Daily Range, Turnover, and Circulating Market Value

Summary

This screening rule selects stocks with a daily price range of at least 1%, circulating market value above 10 billion yuan, and turnover between 3% and 12%. The stated intent is to combine price activity and liquidity with company scale. The article includes formula and sample code that apply these filters to listed stocks, then randomly sample a requested number of names from those that qualify.

The source provides no backtest or evidence of returns. Its discussion raises the possibility that a large-company screen may favor slower-moving blue chips and may not suit investors with limited experience or capital. It recommends considering financial measures such as price-to-earnings and price-to-book ratios, examining volume and industry conditions, and managing exposure with position controls and exits. These suggestions are not converted into tested rules, so the screen should be understood as a basic stock-selection example rather than a validated strategy.

Key ideas
