Screening Chinese Stocks by Amplitude, Relative Volume, and Float Market Value

Summary

This Chinese A-share screening proposal combines daily price range, relative trading volume, and circulating market value. It seeks stocks with amplitude above 1%, volume relative to its five-day average between 1.5 and 6, and float market capitalization above 10 billion yuan. The article presents these thresholds as a way to find stocks with notable movement and active but not extreme trading, while favoring larger listed companies.

The post also includes additional conditions in its formula and sample code, such as price and volume checks and a multi-day price comparison. These details are not fully reconciled with the headline criteria, and the Python snippet’s range condition appears to select values below 1% despite the stated rule. No backtest results or supporting performance evidence are supplied. The author cautions that large capitalization does not guarantee company strength and notes that the screen omits fundamental analysis; suggested refinements include more technical and fundamental inputs.

Key ideas

• The core screen looks for amplitude above 1%, relative volume between 1.5 and 6, and float market value above 10 billion yuan.
• The proposed rationale is to find active stocks with meaningful price movement and substantial market capitalization.
• Formula and code examples add conditions beyond the headline screen and are not fully consistent with it.
• The article gives no backtest evidence and warns that market value alone does not establish business quality.
• The author suggests adding technical and fundamental factors for a broader selection model.
