Screening Main-Board Stocks by Turnover, Float Value, and Volume Ratio
Summary
This stock-selection rule screens main-board shares using three conditions: turnover between 3% and 12%, circulating market value between 5 billion and 10 billion yuan, and a volume-related ratio between 0.5 and 2. The ratio combines the prior day’s turnover with the relationship between the current opening price and prior close, and divides by current turnover. The article provides equivalent screening examples in formula and Python form.
The accompanying discussion says the screen combines liquidity, company size, and recent price-volume activity, and may suit active markets. It also acknowledges that the rule relies on historical market data and leaves out company fundamentals and broader market trends. Suggested extensions include adding valuation and leverage measures, further technical indicators, and review of historical selections. No backtest results, benchmark, holding period, or execution assumptions are supplied, so the document describes a filter rather than demonstrating a profitable strategy. The exact meaning and timing of the volume inputs should also be verified against the data source before implementation.
