A-Share Screen Using Moving-Average Alignment and Convertible-Bond Data

Summary

This A-share screening proposal combines three filters: at least five moving averages are aligned or overlapping, the stock’s 20-day average is above its 120-day average, and a convertible-bond-related field is nonempty. The author interprets clustered averages as possible agreement between shorter- and longer-term trends, and the 20-day versus 120-day comparison as a stronger short-term trend. The sample code further illustrates exact equality among several averages, a nonzero bond field, and additional filters such as RSI, price relative to its average, and price-to-book value.

The document warns that the approach relies on technical analysis, omits company fundamentals in its core logic, and carries market and convertible-bond-related risks. It suggests broadening the moving-average combinations and adding technical and fundamental checks. The description does not clarify why a nonempty convertible-bond name is a desirable screen condition, and exact equality among moving averages may be an unusually restrictive proxy for overlap. No backtest or performance results are provided.

Key ideas

• The proposed screen requires at least five moving averages to overlap and the 20-day average to exceed the 120-day average.
• It also filters on a nonempty field related to outstanding convertible bonds.
• The rationale treats moving-average alignment as a sign that trends across time horizons may agree.
• The sample code adds RSI, price-versus-average, and price-to-book filters beyond the core rules.
• The document identifies limits in technical-only screening and supplies no performance evidence.
