Chinese Stock Screen Combining Amplitude, Market Value, and Positive P/E

Summary

This Supermind screen selects listed Chinese stocks with price amplitude above 1, circulating market capitalization above 10 billion yuan, and a positive price-to-earnings ratio. The proposed rationale is to combine price movement, company scale, and valuation in one filter. The document includes a platform expression and a Python example intended to gather stocks meeting those conditions.

The discussion identifies risks in treating amplitude as a useful signal, relying on P/E without checking earnings quality, and ignoring changes in market conditions. It suggests adding technical measures, company fundamentals, and sector or market analysis, but does not define those additions precisely. No performance results or backtest evidence are reported. The code example also appears to use inconsistent fields and calculations, so it should not be taken as a verified implementation. The filter is best understood as a basic candidate screen rather than a complete strategy with entry, exit, and portfolio rules.

Key ideas

• The screen requires amplitude above 1, circulating market value above 10 billion yuan, and positive P/E.
• It combines a price-movement measure with company scale and an earnings-based valuation measure.
• The document warns that amplitude, P/E, and market conditions can each lead to misleading selections.
• It reports no performance tests, and the supplied code example has inconsistencies.
