Stock Screening with Range, Main-Fund Activity, and Beverage Exports

Summary

The document proposes a Chinese stock screen combining three conditions: daily amplitude above a threshold, evidence interpreted as main-fund control on the prior day, and membership in the beverage manufacturing industry as a proxy for beverage and alcohol import-export exposure. It presents the screen as a way to combine a volatility filter, a capital-flow signal, and a policy-related industry theme. The accompanying pseudocode sketches a price-range calculation and filters for the other two conditions, but does not provide a verified implementation or screening results.

The article acknowledges that the rules omit company fundamentals such as profitability and valuation, and that policy changes can shorten the period in which a theme is relevant. It suggests adding technical indicators, financial measures, and policy analysis. The proposed link between beverage manufacturing and trade-policy support is asserted rather than substantiated, and the meaning of “main-fund control” is not rigorously defined. The screen is therefore a rough idea, not evidence of a reliable trading strategy.

Key ideas

• The proposed screen combines price amplitude, prior-day main-fund activity, and a beverage-industry filter.
• The amplitude condition is intended to focus attention on stocks with larger price ranges.
• The article treats beverage manufacturing as a proxy for exposure to import-export policy.
• It warns that the screen omits profitability and valuation and may be sensitive to policy changes.
• The pseudocode is illustrative and does not establish that the rules are correctly implemented or profitable.
