A Chinese Stock Screen Combining Price Amplitude and Beverage Import-Export Exposure

Summary

This Chinese-language post describes a stock-selection screen for shares associated with beverage and alcohol imports and exports. It combines a price-amplitude filter above 1 with a condition that the stock did not hit its upper price limit on the previous day. The article also includes indicator and Python examples intended to illustrate screening with market data and an industry classification.

The post offers a simple screening recipe rather than a tested trading strategy. It provides no portfolio rules, holding period, transaction-cost assumptions, backtest, or return evidence. Its own risk discussion notes that the approach relies on industry selection and technical indicators while omitting company financial health; it suggests adding fundamental filters and refining sector classifications. The examples may not implement the stated logic consistently, so the screen should be checked carefully before use.

Key ideas

• The screen targets Chinese stocks linked to beverage and alcohol imports and exports.
• It filters for price amplitude above 1 and excludes stocks that hit the upper limit the previous day.
• The post includes indicator and Python examples for implementing a screen.
• It gives no backtest or evidence of investment performance.
• The author identifies missing fundamental analysis and indicator sensitivity as risks.
