A-Share Screen Combining Trading Range, Convertible Bonds, and Hot-List Activity

Summary

This post outlines an A-share stock screen using three conditions: a recent high-to-low trading range above a threshold, a nonempty name for an outstanding convertible bond, and appearance on the previous day’s trading activity list. It presents the combination as a way to find stocks with price movement, a bond-related company characteristic, and recent market attention. The post includes example indicator logic and a Python sketch for obtaining market and bond data, applying filters, and sorting selected names by market value.

The explanation is internally uneven: it describes the bond condition as a basic company indicator, while the supplied implementation filters for bond data, and the stated trading-activity list logic is not clearly justified. The post itself warns that relying on historical indicators and short-term attention can exclude sound companies and says a recent hot list does not establish long-term prospects. It proposes adding valuation, earnings growth, sector, or institutional ownership checks. No backtest, performance evidence, or validation of the code is provided, so the screen is a starting hypothesis rather than a demonstrated strategy.

Key ideas

• The screen combines a minimum daily trading range, an outstanding convertible-bond condition, and recent trading-list activity.
• The post frames these filters as proxies for volatility, company characteristics, and market attention.
• The example code retrieves data, filters candidates, and sorts the results by market value.
• Short-term activity measures do not establish long-term performance, and the post acknowledges selection risks.
• The supplied material gives no backtest or evidence that the rules produce positive returns.
