What You Can Learn from Europe’s “Dow Theory”-esque Non-confirmation

July 18, 2024

By Brian Whitmer | European Financial Forecast editor

Charles Dow (yes, the one with the averages named after him) developed a foundational concept in technical analysis that requires that price movement in industrial stocks and transportation shares confirm one another.

The main condition for a Dow Theory non-confirmation occurs when one sector makes a new extreme absent the other. Its classic application is observing the position of the Dow Jones Industrial Average, an index of 30 “industrial” stocks, versus the position of the Dow Jones Transportation Average, an index of 20 “transportation” stocks. In essence, whenever one index fails to keep up with the other, in either direction, it suggests an impending reversal.

These concepts can be applied universally.

For example, right now over in Britain, the FTSE 100’s divergence with the FTSE 350 Transportation Index just pushed to 29 months.

Britain's Longest Nonconfirmation to Date

This is a far more prolonged Dow Theory non-confirmation than that seen in July 2007 (seven months) or December 1999 (17 months). In 1999, the FTSE 100 eventually collapsed 53%, while the FTSE 350 Transports fell 66%. In 2007, the resulting declines were 49% and 77%, respectively.
