A-Share Screening with Trading Range, Convertible Bonds, and Earnings Growth
Summary
This document proposes screening A-share stocks for price amplitude above 1, a nonempty outstanding convertible-bond name, and year-over-year growth in net profit attributable to parent-company shareholders above 20% and at most 100%. It presents amplitude as a rough signal of market activity, bond issuance as information about financing, and earnings growth as a measure of company expansion. Reference formulas and Python-style code are included to illustrate implementation.
The article does not provide a backtest or evidence that these filters lead to better returns. It warns that the screen omits other company and valuation factors and that prices and earnings growth can fluctuate, potentially overlooking long-term considerations. There is also an implementation mismatch: the written rule says amplitude above 1, while the displayed formula tests a negative one-day return threshold, and the sample code uses recent declining candle conditions rather than a direct amplitude calculation. The selection logic should therefore be reconciled and validated before use.
Key ideas
- The stated screen combines price amplitude, an outstanding convertible bond, and a bounded earnings-growth condition.\nThe article frames these criteria as a mix of market activity, financing information, and fundamentals.\nIt provides formula and Python-style examples but no performance results.\nThe displayed formula and code do not clearly implement the written amplitude condition.\nThe source recommends considering additional financial and valuation factors.
