Screening Chinese Stocks by MACD, Three Down Days, and Limit-Ups

Summary

This Chinese equity screen combines three conditions: MACD above its zero axis, three consecutive down days, and at least two limit-up sessions within the previous 500 days. The accompanying discussion frames positive MACD as a trend filter and prior limit-ups as a sign of potential price strength. It also describes a weekly selection workflow and gives example indicator settings and a portfolio allocation approach.

The article flags risks including reliance on a narrow set of technical conditions, sensitivity to noise, the hazards of trading around limit-up moves, and omission of fundamentals. It suggests adding indicators and fundamental or sentiment data, but does not test whether these changes improve results. Its example implementation also has ambiguities: the down-day condition is not clearly aligned with the stated three-day requirement, and counting positive high-limit prices does not establish how many limit-ups occurred. No backtest results or evidence of profitability are presented.

Key ideas

• The screen requires positive MACD, three consecutive declining sessions, and at least two limit-up events over 500 days.
• The example proposes weekly stock selection and distributes portfolio value across selected names.
• The discussion warns that a small set of technical filters can be noisy and omits fundamental information.
• The code example does not clearly verify the stated three-day decline or count actual limit-up events.
• The article supplies no performance results for the strategy or its suggested refinements.
