Screening Chinese Beverage and Alcohol Stocks by Turnover and Control Ratio

Summary

This stock-selection rule screens Chinese beverage and alcohol-related companies using three conditions: turnover between 3% and 12%, membership in a beverage and alcohol import-export category, and a reported daily control ratio above 21%. The article describes the control-ratio condition as an added filter intended to find shares with a higher degree of price control. It includes example formulas and Python code that illustrate a possible implementation with market data.

The article gives no backtest, portfolio construction method, or performance evidence. Its risk discussion notes that focusing on turnover, sector classification, and a control measure leaves out many other influences on stock quality and price behavior. The code example also applies additional filters, including market-capitalization and profitability constraints, and appears to derive the control ratio from block-trade data; these implementation choices are not reconciled with the stated screening rule. The result should therefore be treated as a rough screening example rather than a validated strategy.

Key ideas

• The stated screen combines turnover between 3% and 12%, a beverage and alcohol category, and a control ratio above 21%.
• The control-ratio filter is intended to identify shares described as more tightly controlled.
• The example code includes additional market-capitalization and profitability filters beyond the main rule.
• The document reports no performance evidence and warns that the screen omits other relevant factors.
