A-Share Screen for Range, Convertible Bonds, and a 30-Day Average

Summary

The document describes a Chinese stock screen combining three conditions: daily high-low range of at least one percent, a nonempty name for an outstanding convertible bond, and a close above the 30-day moving average. It presents the screen as mixing price movement, convertible-bond information, and a trend filter, with a sample indicator formula and Python-style implementation. The code also refers to exchange listings and additional financial data, but its screening logic is not fully consistent: the written rule says the moving average is rising, while the formula checks that the close is above the average, and the code includes extra dividend and listing filters.

The article offers no backtest results or return evidence. It warns that the criteria are limited and may favor short-lived hot stocks, and suggests adding financial or valuation measures. The convertible-bond condition’s intended meaning is not clearly explained, and the code’s required fields and data handling would need verification before use. The screen should be treated as an example for further research, not a validated strategy.

Key ideas

• The stated screen requires a daily high-low range of at least one percent, convertible-bond name data, and a close above the 30-day moving average.
• The article describes the moving-average condition as rising, but its formula tests whether the close is above the average.
• The sample implementation adds extra financial and listing filters that are not part of the three stated conditions.
• The article provides no performance evidence and recommends incorporating broader company fundamentals.
• The convertible-bond criterion and code details need clarification and verification before the screen is used.
