Screening Chinese Stocks by Amplitude, Float Size, and New Lows

Summary

This stock screen combines three conditions: amplitude above 1, a circulating share count no greater than 5.5 billion, and a current-day low below the previous day’s low. The post frames the amplitude and float filters as ways to focus on volatile, relatively smaller-capitalization stocks, and the lower low as a possible sign of rebound potential. Its example selection code also ranks qualifying names by turnover rate and limits the final list to a fraction of the stock universe, though this ranking step is not part of the stated core criteria.

The post notes that stocks meeting these conditions may continue to fluctuate or move sideways, and that a smaller eligible universe can restrict selection. It suggests supplementing the screen with technical and fundamental measures, plus risk controls such as profit-taking or stop-loss rules. The document offers no historical results or evidence that a lower low predicts a rebound; its stated rationale remains a hypothesis, and the example code is reference material rather than a tested strategy.

Key ideas

• The core screen requires amplitude above 1, a float of at most 5.5 billion shares, and a lower daily low than the previous day.
• The post treats a lower low as a possible rebound setup, not a confirmed reversal.
• Its example code ranks qualifying stocks by turnover rate and caps the selection size.
• The author identifies sideways movement and a restricted stock pool as risks.
• No backtest or other evidence validates the proposed rebound rationale.
