Classic Dow Theory

A lot of times you hear clowns spout dow theory which is basically the three cores to the US economy rising together or not. The three cores (maybe there are more now?) Industrial, Utility, and Transportaion - and currently Utility hit a new high which Industrials didnt and Transportations have been woefully lagging. That's it. No predictive ability but an observation that some things are weaker than other and possibly an indicator for more volatility?
