Screening Chinese Stocks by Amplitude, Control, and Price

Summary

The post outlines an equity screen based on daily price amplitude, a measure labeled shareholder control, and a closing-price threshold. It frames higher amplitude and control readings as ways to find active, volatile stocks, while treating price as a constraint. The examples include platform formulas and Python-like pseudocode that apply the conditions and rank qualifying stocks by market capitalization.

The post cautions that recent volatility and a single price level can overlook long-term value and price trends. It proposes adding company fundamentals and technical indicators, and choosing a price near the middle of a stock's trading range. The proposed refinements are not accompanied by backtests or evidence of improved selection. There is also a mismatch between the headline's price condition and the later screening examples, so the intended threshold is unclear; the code and indicator definitions would need checking before use.

Key ideas

• The initial screen combines daily amplitude, a shareholder-control measure, and a closing-price threshold.
• The examples rank selected stocks by market capitalization after applying the screen.
• The post warns that recent volatility and a single price level can miss fundamental and trend information.
• It suggests adding fundamental and technical filters and using a price near the trading-range midpoint.
• The stated price threshold varies within the document, and the proposed method has no reported test results.
