A-Share Screen Using Convertible Bonds and Opening Price Conditions

Summary

This Chinese-language post describes an A-share stock screen combining price range, convertible-bond, and early-session price conditions. The stated rules require an amplitude above a threshold, a nonempty outstanding convertible-bond name, and a 9:25 price move below a ceiling. Its indicator example also applies market-capitalization, exchange, listing, industry, and price-direction filters. A Python example sketches how to retrieve stock, company, bond, daily, and minute data to form and sort a candidate list.

The post offers no historical backtest, performance figures, or evidence that the filters predict returns. It acknowledges that the 9:25 move does not indicate subsequent price direction and that the screen may exclude volatile stocks with larger upside. The rule descriptions and code do not align fully: the examples add restrictions beyond the headline logic, so the implementation would need checking before use. The post suggests adding valuation and leverage measures for broader assessment, but does not specify how to combine them or validate the resulting screen.

Key ideas

• The screen combines intraday amplitude, convertible-bond association, and an early-session price filter.
• The code examples add market-capitalization and other eligibility restrictions to the stated rules.
• The post provides implementation sketches but no backtest or evidence of predictive performance.
• An early-session price change may not indicate the rest of the day's direction.
• Additional valuation and leverage measures are suggested, without a defined validation method.
