Here are the industries with 25% or more of their stocks advancing today.
EP, which is one of the leading stocks in the group. The rest of the group is moving in sympathy, with some making some pretty big moves, and some others may become acquisition targets (at least that is the theory). This was formerly the strongest group in the market, but got hit very hard in the latest correction. It appears to be regaining some strength, but I doubt that this latest move will be able to sustain itself long.
