The Dow Jones Industrial Average has climbed back above the 13,000 level to challenge the high from earlier this year. However, weakness in its counterpart, the Dow Jones Transportation Average, has led some to question the rally.

“There are at least two reasons to take the Dow Transports’ weakness seriously. The first is that many claim that the transportation sector often acts as a leading indicator of the overall economy,” writes Mark Hulbert at MarketWatch.

“The other reason to take seriously the pronounced weakness in the Dow Transports: It is one of the two Dow averages on which the venerable Dow Theory is based,” Hulbert observes. “Only new highs that are jointly hit by both averages are considered evidence of a healthy bull market.”

For the month ended Aug. 9, the iShares Dow Jones Transportation Average (NYSEArca: IYT) was down 2.8%, while the SPDR Dow Jones Industrial Average (NYSEArca: DIA) rose 3.6%, according to Morningstar.

“To be sure, not all Dow Theorists see eye to eye right now on whether the Theory is on a buy or a sell signal. But they all agree that the transports’ weakness is of concern,” Hulbert writes.

Below is a chart of the relative performance of the Transportation ETF versus the Dow. When the chart is falling, the transportation sector is underperforming the Dow.
