A Chinese Stock Screen Combining Amplitude, Turnover, and Positive P/E

Summary

This post describes a Chinese stock screen requiring price amplitude above a stated threshold, turnover within a specified band, and a positive price-to-earnings ratio. It frames the criteria as a blend of price movement, trading activity, and a basic valuation filter. Formula and data-fetching examples illustrate how the conditions could be applied to listed stocks, but the post does not provide a tested portfolio or trading rules for entry, exit, or sizing.

The author notes that P/E can be affected by past earnings and market conditions, and that volatile stocks carry risk. Suggested refinements include adding technical measures and broader financial indicators such as profitability and financial strength. Despite language suggesting the screen may reduce risk, there is no backtest, comparison, or empirical evidence supporting that claim. Thresholds and data definitions also need careful verification in implementation, particularly when matching turnover units and screening dates. Treat this as a basic candidate filter rather than evidence of an effective strategy.

Key ideas

• The screen requires elevated amplitude, turnover inside a stated range, and positive earnings valuation.
• The post combines price, trading-activity, and fundamental criteria to select candidate stocks.
• Examples illustrate formula-based and data-driven implementations of the filters.
• The document provides no backtest or evidence that the screen improves returns or reduces risk.
• It suggests supplementing the criteria with technical and broader financial measures.
