A-Share Stock Screen Using Trading Range, Convertible Bonds, and Listing Age

Summary

This Chinese-language post proposes screening listed Chinese stocks using price movement, the presence of an outstanding convertible bond name, and a minimum listing age. It explains the intended rationale as combining trading activity with indicators that may reflect company history or strength. A sample formula adds turnover and excludes some stock categories, while the Python example attempts to filter for recent price range, turnover, and a listing history of at least six months.

The post acknowledges that these conditions omit broader market direction, long-term trends, and company fundamentals, and recommends adding valuation, growth, profitability, and market context. It does not report a backtest or evidence that the screen generates returns. The explanation also treats convertible-bond availability and listing age as rough proxies for company quality, so those assumptions should not be interpreted as established relationships. The code is illustrative and contains inconsistencies between the prose and implementation.

Key ideas

• The proposed screen combines stock price range, a convertible bond listing condition, and minimum listing age.
• The example formula also applies a turnover threshold and excludes selected stock categories.
• The post suggests adding valuation, growth, profitability, and market context to reduce reliance on a few screening rules.
• Listing age and convertible bond availability are presented as possible proxies for company history or strength, without supporting evidence.
• No performance test is provided, and the sample implementation does not consistently match the stated logic.
