I recall folks here remarking on the divergence on the dow transports; (hitherto I never heard anyone call it the "Dow Theory")

Investors beware of the Dow Theory’s bite
By Michael Mackenzie in New York
Amid all the optimism that has driven global share prices higher, a warning signal has been flashing in the US market. Key equity markets have rallied 20 per cent since October on investor hopes that Europe might eventually muddle through its crisis and China will negotiate a soft economic landing.
However, the earnings outlook is increasingly cloudy and one popular market trend watched closely by investors – the relationship between the Dow Jones Transportation Average and the broader Dow Jones Industrial Average – is signalling caution.
Under an old market rule of thumb popularly known as “Dow Theory”, when this relationship diverges, it is an early warning that a change in broad market sentiment is brewing. This month the Dow Jones Transportation Average, consisting of 20 airline, railway, shipping and freight companies and thus seen as a solid barometer of underlying economic activity, hit its high for the year, a gain of 33 per cent since shares bottomed last October.
Subsequently, transports have turned and are down 1.5 per cent this month. That contrasts with the Dow Jones Industrial Average’s gain of 2.5 per cent in February, an overall rally of 21.5 per cent since last October.
