Screening Chinese Stocks by Amplitude, Float, and Beverage Trade Activity

Summary

This post describes a Chinese equity screen that combines prior-day price amplitude above 1%, a free float no larger than 5.5 billion shares, and evidence of beverage or alcohol imports or exports. It explains the intended rationale: seek stocks with notable short-term price movement, smaller share floats, and exposure to a specific trade-related industry. Example formulas show how to calculate amplitude from the previous high, low, and close, then intersect the three conditions.

The post cautions that float and amplitude filters do not address weak company fundamentals and that a narrow industry criterion may miss other opportunities. It suggests adding indicators such as RSI, KDJ, or Bollinger Bands and assessing industry conditions and company fundamentals. The examples are screening references rather than a complete trading system: there are no entry or exit rules, portfolio controls, backtest results, or evidence that the screen is profitable. The stated thresholds and classification depend on the supplied data and definitions.

Key ideas

• The screen selects stocks with prior-day amplitude above 1%, free float at or below 5.5 billion shares, and beverage or alcohol import or export activity.
• The three conditions are combined as an intersection to identify qualifying stocks.
• The post presents volatility and smaller float as possible sources of short-term opportunity, not as proven return drivers.
• It recommends supplementing the screen with technical indicators and fundamental and industry analysis.
• No backtest, trading rules, or performance evidence is provided.
