A-Share Stock Screen Using Price Amplitude and Profit Growth

Summary

This document describes a China A-share screening strategy that excludes Beijing-listed and certain other regional stocks, requires daily price amplitude above 1%, and selects companies with positive net profit and year-on-year net profit growth from above 20% through 100%. It also shows how to express the filters in a charting platform and in Python, then adds moving-average and MACD calculations before selecting stocks at a recent high.

The rationale is that moderate-to-strong profit growth and positive earnings may help identify companies with sound performance, while the amplitude filter favors stocks with some price movement. The author cautions that growth alone omits market and policy conditions and ignores the absolute scale of profits. Suggested improvements include combining financial measures and considering broader conditions. No backtest results, portfolio rules, or trading risk controls are provided. The heading gives a different growth threshold from the detailed strategy, and the sample code’s stages may not consistently apply the amplitude filter, so the specification should be checked before implementation.

Key ideas

• The screen excludes Beijing and specified regional stocks and requires daily amplitude above 1%.
• It selects positive net profit and year-on-year net profit growth above 20% and no greater than 100%.
• The document suggests combining growth with other financial and market information.
• It provides platform-specific and Python examples but reports no performance evidence.
• The title threshold conflicts with the detailed screening rules, so the intended threshold needs verification.
