Chinese Beverage and Alcohol Stock Screen Using Volatility and Limit-Up Events

Summary

The post proposes a Chinese stock watchlist screen for companies associated with beverage or alcohol imports and exports. It combines daily price amplitude above 1% with at least one limit-up event in a recent window. The accompanying indicator and Python examples implement the conditions with price data and industry membership, and the Python example ranks qualifying observations by a volume-related measure.

The author argues that volatility and a prior limit-up may indicate potential strength, and that the targeted subindustry can respond to policy shifts. The post also flags policy sensitivity, sector cycles, and market volatility, and suggests adding company financial measures. It does not provide a backtest or evidence that the signals lead to excess returns. The code and prose also differ on the exact recent-event window, so the implementation should be checked before use.

Key ideas

• The proposed screen combines daily amplitude above 1% with a recent limit-up event.
• It restricts candidates to beverage and alcohol import-export related companies in the food and beverage sector.
• The example code includes industry membership checks and ranks selected observations by a volume-related measure.
• Policy shifts, sector cycles, and market fluctuations are identified as risks.
• The post gives no performance test, and its descriptions of the event window are inconsistent.
