A-Share Stock Screen Using Moving Average Convergence and Opening Gains

Summary

This A-share stock selection proposal combines three initial filters: at least five overlapping moving averages, circulating market capitalization above 10 billion yuan, and a gain below 6% at 9:25. It interprets converging averages as a sign of closely aligned price trends, larger capitalization as a preference for bigger companies, and a modest pre-open gain as room for further movement. The article’s later version adds rising moving averages and Bollinger Bands as trend conditions.

The post gives a conceptual rationale and sample code, but the code’s data calls and selection checks do not clearly establish the stated conditions. It provides no backtest, transaction costs, benchmark, or evidence of returns. The authors also acknowledge that technical filters omit company fundamentals and that market sentiment and company results can affect prices. Treat the screen as an unvalidated idea that would require precise definitions, reliable data, and testing before practical use.

Key ideas

• The proposed screen combines converging moving averages, a market capitalization threshold, and a limit on the pre-open gain.
• A later version adds rising moving averages and Bollinger Bands as trend filters.
• The article warns that technical filters do not account for company fundamentals or all market drivers.
• No backtest or performance evidence is provided, and the sample code does not clearly validate the described conditions.
