Chinese Stock Screen Using Weekly MACD and Recent Limit-Up Activity

Summary

This stock-selection screen combines three technical conditions: daily amplitude above 1%, weekly MACD above zero, and at least one limit-up session within the previous 25 days. The document presents these as filters for volatility, positive trend conditions, and recent market interest. It gives indicator formulas and a Python-style example, but no backtest, performance figures, or evidence that the conditions predict future returns.

The author cautions that the screen ignores company fundamentals, industry conditions, and policy risks. Recent limit-up activity may also draw attention to short-lived momentum that fades. The suggested improvement is to combine technical signals with business, market, and policy analysis and to consider longer-term investment value. The examples should be treated as illustrative: the Python snippet mixes daily data with weekly MACD references and contains apparent implementation inconsistencies, so it does not establish a verified, reproducible strategy.

Key ideas

• The screen requires daily amplitude above 1% and weekly MACD above zero.
• It also requires at least one qualifying limit-up session in the prior 25 days.
• The document supplies indicator formulas but provides no performance test.
• Fundamental, industry, and policy factors are absent from the screen.
• Recent limit-up activity can be followed by a loss of momentum.
