A-Share Screen Using Positive MACD and Recent Limit-Up Days

Summary

This A-share stock selection rule looks for a positive MACD reading, a short-term upward moving-average condition, and more than two limit-up days within a ten-day window. The accompanying explanation interprets positive MACD and rising averages as signs of an upward trend, while repeated limit-ups are treated as evidence of strong recent performance. The example formulas define MACD from exponential moving averages, identify a limit-up event, and propose sorting qualifying stocks by trading volume.

The document warns that this compact screen does not capture a company's full investment value and that recent limit-up counts may be noisy. It suggests adding technical and fundamental filters and considering industry context to reduce reliance on short-lived attention. The formula shown for the moving-average condition compares one-day and two-day averages, which is narrower than the prose description of averages spreading upward; the Python example also uses different moving-average periods. No backtest, market-regime analysis, or measured results are presented, so the screen is a rule sketch rather than validated evidence of an edge.

Key ideas

• The screen requires MACD above zero and more than two limit-up sessions in the recent ten-day period.
• The written rule also calls for an upward moving-average condition.
• The example proposes sorting selected shares by trading volume.
• The formula examples do not consistently express the described moving-average condition.
• The author cautions that limit-up counts can be noisy and that the screen omits broader valuation and context.
• No test results are supplied to establish the screen's effectiveness.
