Screening Chinese Stocks Above the MACD Zero Line by Attention and Scale

Summary

This stock-screening proposal selects shares whose MACD is above zero, whose reported company scale exceeds a stated threshold, and whose investor attention ranks relatively high. Screening is intended to run after the daily close. The article gives the conventional MACD construction using exponential moving averages of closing prices, and supplies a Python example intended to filter securities before sorting the survivors. Its rationale is that positive MACD may indicate trend strength, attention reflects market interest, and company scale may help exclude smaller firms.

The article warns that this combines a narrow set of signals: MACD alone can misread market conditions, attention can be an incomplete proxy, and scale does not establish profitability or future performance. It suggests adding technical and fundamental measures, but presents no backtest, portfolio results, or validation of the screen. The example code does not clearly implement the stated attention ranking, and its sorting step uses closing price; the displayed scale threshold and data handling also warrant verification before use. The proposal is a screening concept, not evidence of a profitable strategy.

Key ideas

• The proposed screen requires MACD to be above its zero line.
• It combines the indicator condition with a company-scale cutoff and a ranking by stock attention.
• The article describes MACD using exponential moving averages of closing prices.
• The authors identify risks from relying on a narrow set of indicators and treating company scale as a proxy for quality.
• The supplied example does not clearly implement the stated attention ranking and provides no performance evidence.
