A-Share Screen Using Price, Intraday Range, and Ownership Concentration
Summary
The document describes a Chinese stock screening rule combining an intraday range threshold, a specified share price, and a 20-day concentration measure. It frames the screen as a way to find stocks with a particular price and activity profile while avoiding excessive ownership concentration. The listed conditions appear inconsistently: the title says a price of 18, the prose and final rule specify 18.5, and the concentration wording conflicts with the formula, which selects values above 70.
No backtest results or performance evidence are provided. The accompanying discussion cautions that these filters omit company financials, industry outlook, and management quality, and suggests adding such factors or other market and technical filters. The code examples are references rather than a fully consistent implementation: the Python section does not clearly apply all stated criteria. The screen therefore needs its thresholds and definitions reconciled and tested before practical use.
Key ideas
- The proposed screen combines price, intraday range, and a 20-day concentration measure.
- The title and body disagree on the price threshold, and the concentration condition is internally inconsistent.
- The document gives no performance evidence for the screening rule.
- Company fundamentals and industry conditions are identified as missing inputs.
