Mainland China Stock Screen Using Range, Weekly MACD, and Daily Gains

Summary

This post proposes screening mainland China main-board stocks for a daily trading range above one percent, weekly MACD above zero, and a positive daily move exceeding one percent. It frames the combination as a way to identify shares with short-term upward momentum, using price movement and a trend indicator rather than company fundamentals. The post also suggests checking broader market sentiment and adding other technical conditions, such as a MACD crossover.

The article supplies formula and Python examples, but the examples do not fully match the stated screen: the Python uses a particular historical date window and a weekly MACD crossover, while the written rule specifies MACD above zero. No backtest, performance statistics, or selected-stock results are presented. The author acknowledges that omitting financial and business fundamentals can leave the screen exposed to overbought or unstable shares, and that market volatility remains unpredictable. Treat it as a rough screening idea that would need precise definitions, reliable data, and out-of-sample evaluation before use.

Key ideas

• The proposed screen combines a daily range threshold, positive weekly MACD, and a daily gain threshold.
• The selection universe is mainland China main-board equities.
• The post recommends considering fundamentals, market sentiment, and additional technical filters.
• Its code example differs from the written rules, so the screening conditions need clarification.
• The document reports no backtest evidence and warns that market risk and overbought selections remain possible.
