Chinese Beverage Stock Screen Using Turnover and Trading-Flow Ratios
Summary
This stock-selection idea screens for Chinese beverage and alcohol-related companies, with turnover between 3% and 12% and a buying-versus-selling activity condition described as external volume exceeding internal volume by a factor greater than 1.3. The document gives both a platform-style screening expression and a Python example using market data, industry labels, turnover, and volume-derived fields. It presents the conditions as a way to combine industry exposure with a short-term trading-activity signal.
No historical backtest, return series, or risk-adjusted evidence is supplied, so the screen's effectiveness cannot be assessed from the document. The author notes that it omits fundamentals, competitive position, and industry outlook, leaving substantial company-specific and market risk. The Python field transformations also require careful validation against the data provider's definitions: the code's constructed volume ratio may not directly represent the external-to-internal volume ratio stated in the screening rule. The criteria are therefore a starting filter, not a complete investment process.
Key ideas
- The screen targets beverage and alcohol-related equities with turnover in a specified range.
- It adds a trading-activity condition based on external volume relative to internal volume.
- The document offers both a platform screening expression and a Python data-processing example.
- It supplies no performance evidence and omits company fundamentals and competitive factors.
- The data fields and ratio calculation should be checked against the intended volume definitions.
