Chinese Stock Screening with Sustained ROE and Convertible Bond Listings

Summary

This Chinese stock screen combines daily amplitude above 1, return on equity above 15% over five consecutive years, and a nonempty name for an outstanding convertible bond. The article presents the bond listing as a way to consider the relationship between a company's equity and its convertible financing, alongside a measure of sustained profitability. It also sketches formula and Python implementations, although the examples contain placeholders and their conditions do not consistently express all the prose criteria.

The discussion flags interest-rate, credit, and liquidity risks in convertible bonds, as well as the possibility that bond and stock prices may diverge. It characterizes the overall screen as simple and recommends adding financial and market measures, examining volatility, and using risk controls such as stop-loss rules. The article offers no backtest or other evidence that this combination predicts returns. Its incomplete sample code and ambiguous encoding of the five-year ROE condition make the rule difficult to reproduce as written.

Key ideas

• The screen requires amplitude above 1, sustained ROE above 15%, and an outstanding convertible bond name.
• Convertible bond exposure introduces interest-rate, credit, and liquidity risks.
• The stock and bond markets are related but their prices do not necessarily move together.
• The sample implementations include placeholders and may not faithfully encode the stated screening rules.
• The article recommends broader evaluation and risk controls but presents no performance evidence.
