Combining a Morning-Star Pattern with Five Years of High ROE

Summary

This A-share screen combines daily amplitude above 1%, a candlestick pattern described as a morning star, and return on equity above 15% for five consecutive years. It aims to pair a technical reversal-style signal with a sustained profitability filter. The article also gives sample indicator and Python implementations, though it does not specify a full entry, exit, or portfolio-allocation method.

The document presents no backtest or realized performance evidence. It cautions that the screen leaves out macroeconomic and industry conditions, and that ROE can be affected by accounting or management choices, making additional measures of valuation, growth, and financial quality useful. The sample implementation describes its own candle checks, but the article does not demonstrate that they reliably identify the named pattern. The method should therefore be read as a proposed screen whose pattern definition and financial data handling require validation.

Key ideas

• The screen requires amplitude above 1%, a morning-star candlestick pattern, and ROE above 15% for five consecutive years.\nIt combines a technical pattern with a persistent profitability criterion.\nThe article recommends considering industry conditions, valuation, growth, and financial quality.\nIt warns that ROE alone may give an incomplete view of company profitability.\nNo backtest or performance evidence is provided, and the pattern implementation is not validated.
