Weekly MACD and Opening-Auction Value for Stock Selection

Summary

This stock screen combines daily amplitude above 1 with a positive weekly MACD histogram, then ranks qualifying stocks by the value traded in the opening auction and selects the top five. The article interprets strong auction value as a sign of market attention and buying interest. Its examples show formula and Python-style implementations, though the code uses different proxies and does not fully clarify how auction value or the ranking is calculated.

The author warns that the method relies heavily on technical signals and market sentiment while ignoring much of company fundamentals. A high auction ranking can reflect short-lived attention and may encourage buying into a move that reverses. Suggested refinements include treating auction value as one input among several and adding other technical and fundamental measures. The document offers a screening hypothesis and implementation sketches, but reports no historical test, returns, transaction costs, or evidence that the top-ranked stocks outperform. Its threshold and selection rules should be checked against the target market's data definitions before use.

Key ideas

• The screen requires amplitude above 1 and a positive weekly MACD histogram.
• It ranks qualifying stocks by opening-auction value and selects the top five.
• The article treats auction activity as an indicator of market attention and buying interest.
• The author recommends combining the ranking with technical and fundamental information.
• No backtest or performance evidence is provided, and the sample code leaves data definitions unclear.
