Screening Stocks by Price Amplitude, Recent Top-List Appearance, and Positive P/E

Summary

This Chinese equity screen combines price amplitude above one, appearance on the previous day’s market top list, and a positive price-to-earnings ratio. The article interprets amplitude as a sign of short-term volatility, top-list inclusion as a possible signal of near-term speculative attention, and positive P/E as a way to exclude companies with negative earnings. Its sample logic intersects those three filters and orders qualifying stocks by closing price.

The article describes possible risks: investor speculation may overwhelm fundamentals, capital flows around top-list names require closer review, and attention to a sector or theme may fade. It suggests adding valuation measures such as PEG or price-to-sales, technical signals such as MACD or KDJ, and a more limited P/E range. These are proposals rather than tested improvements. The document provides no backtest or performance data, and the relationship between positive P/E and lower risk is asserted without supporting analysis, so the screen’s predictive value remains unestablished.

Key ideas

• The screen requires amplitude above one, previous-day top-list appearance, and a positive P/E ratio.
• The article treats top-list inclusion as a possible sign of short-term speculative interest.
• It warns that fading themes and speculative flows can undermine the screen’s rationale.
• Suggested additions include other valuation measures, technical indicators, and a narrower P/E range.
• No empirical performance evidence is provided to validate the filters or proposed refinements.
