A-Share Screening with Price Amplitude, Morning Star, and Positive P/E

Summary

This note describes an A-share stock screen combining daily price amplitude above 1, a morning-star pattern, and positive price-to-earnings ratio. It presents the pattern as a short-term technical signal and positive P/E as a basic profitability filter. It also suggests broadening fundamental review with measures such as price-to-book ratio and return on equity, and combining technical indicators rather than relying on a few fixed rules.

The document includes example indicator and Python logic, but those implementations do not cleanly match the stated screen: the Python example filters turnover rate rather than directly checking amplitude, and its pattern conditions are a particular approximation. No backtest results or evidence of predictive performance are given. The note itself flags that positive P/E is permissive and that a narrow set of conditions may create strategy risk; it also leaves execution, position sizing, and risk controls unspecified.

Key ideas

• The proposed screen combines amplitude above 1, a morning-star pattern, and positive P/E.
• The note treats the candlestick pattern as a short-term trend signal and P/E as a basic fundamental filter.
• Positive P/E alone can admit companies with weak fundamentals.
• The code examples do not fully implement the stated criteria, and the document reports no performance evidence.
