Screening Chinese Stocks by Amplitude, Float Value, and Popularity

Summary

This stock-selection screen combines a minimum daily amplitude threshold with a minimum circulating market capitalization, then ranks qualifying shares by a popularity measure. The stated rationale is to focus on stocks that show price movement, have a larger float value, and attract market attention. The source identifies amplitude, circulating capitalization, and popularity as the screening dimensions, but offers no historical test or evidence that the combination predicts returns.

The document flags that market attention can shift quickly and that popularity measures or research judgments may be incomplete. It suggests tracking themes and adding fundamental and technical considerations, though it does not specify how to do so. Its accompanying code reference appears inconsistent: the stated ranking variable is popularity, while the sample sorting key uses listing date, and the described amplitude calculation uses a historical range. These details make the implementation difficult to treat as a faithful, reproducible version of the stated screen.

Key ideas

• The screen filters for stocks above stated amplitude and circulating market capitalization thresholds, then ranks them by popularity.
• The proposed rationale is to combine price movement, company scale, and investor attention.
• The document warns that market themes and attention can change, making popularity-based ranking unstable.
• No backtest or return evidence is provided, and the sample code appears inconsistent with the stated popularity ranking.
