“The Dow Jones Industrial average has gained about 1,200 points over the past month. And interestingly, nearly half of that advance has been produced by just three stocks.
Leading the field by a wide margin is Goldman Sachs: That stock’s 26.5 percent rally over the past month has added about 320 points to the Dow. In second place is UnitedHealth, which is up about 15.7 percent, and has consequently tacked about 150 points onto the 30-stock index. Finally, Caterpillar‘s 17.3 percent run had added about 95 points, just ahead of JPMorgan‘s 90-odd point contribution.”
