Chinese Beverage Stock Screen Using Turnover and Bollinger Bands

Summary

This document describes a Chinese stock selection screen combining beverage and alcohol industry membership, turnover, and a Bollinger Band condition. The stated setup seeks stocks with turnover between 3% and 12% and closing prices between the middle and upper Bollinger bands. A code example adds further filters, including a history of reported business results, lower institutional ownership concentration, a market capitalization threshold, and sorting by company size. These extra filters do not all match the shorter strategy description, so the specification is internally inconsistent.

The post says Bollinger Bands may fail to represent a stock’s full trend and that an industry-specific screen can miss rising sectors elsewhere. It suggests adding industry fundamentals such as market share and growth. No backtest, performance data, or evidence for the claimed reliability is provided. The example also appears to use an upper-band comparison that conflicts with the stated between-bands rule, so the exact intended signal should be checked before implementation.

Key ideas

• The stated screen combines beverage and alcohol industry membership with turnover between 3% and 12%.
• The described price condition places the close between the middle and upper Bollinger bands.
• The code example adds financial-history, ownership, and market-cap filters beyond the main screen description.
• The post identifies limited industry coverage and the shortcomings of Bollinger Bands as risks.
• No historical test or performance evidence is included, and parts of the example conflict with the stated rule.
