Screening Chinese Stocks by Price Range, Listing Code, and Convertible Bonds

Summary

This note describes a Chinese stock screening rule that combines daily price amplitude above one percent, a stock code beginning with 60, and a nonempty name for an outstanding convertible bond. The code examples show how to express these filters and rank qualifying stocks by the difference between the current open and the previous close. The stated rationale is to find relatively volatile stocks with convertible-bond issuance attributes.

The article offers no backtest, performance results, or evidence that these conditions predict returns. It warns that limiting the universe to this code prefix and bond attribute can exclude other candidates, and that higher volatility and convertible-bond market policy or liquidity changes add risk. It suggests adding market and fundamental data, plus stop-loss and diversification rules, but does not specify or evaluate them. The examples are screening references rather than a fully specified or validated trading system.

Key ideas

• The screen requires amplitude above one percent, a stock code beginning with 60, and an outstanding convertible bond name.
• Qualifying stocks are ranked by the current opening price minus the previous close.
• The article provides formula and Python examples but no measured strategy performance.
• It identifies volatility, universe exclusions, and convertible-bond liquidity or policy shifts as risks.
