A-Share Screen Using Trading Range, Convertible Bonds, and Float Capitalization

Summary

The document describes an A-share stock screen combining three conditions: price amplitude above 1%, a nonempty name for an outstanding convertible bond, and tradable market capitalization above 10 billion yuan. It presents the screen as a way to focus on larger companies, and includes example implementations in a charting formula and Python using market data. The code also applies additional filters, so it does not cleanly match the stated three-condition rule.

The article warns that a large market value does not establish company quality and that the screen may exclude smaller firms with growth potential. It suggests adding financial measures such as revenue, profit, earnings, and cash flow, as well as valuation measures, for a broader assessment. No backtest, performance results, or evidence that the conditions predict returns is provided. The threshold and filters are presented as adjustable choices, so the screen should be understood as a basic selection rule rather than a validated trading strategy.

Key ideas

• The proposed screen requires amplitude above 1%, an outstanding convertible bond with a nonempty name, and float capitalization above 10 billion yuan.
• The document provides charting-formula and Python examples, but the Python implementation adds filters beyond the stated rule.
• Large capitalization alone does not guarantee business quality or reduce valuation risk.
• The author suggests combining the screen with financial and valuation measures.
• The document reports no test results establishing the screen's profitability.
