Starting with Alcoa (AA), he said that this is a stock that has been on a "rampage." It is up 30% already, and Cramer said he sees it going to either $42, in the event it gets taken over, or $45 on its own earnings.

American Express (AXP), the second Dow stock Cramer named, is up only 5% this year, he said. The company's "remarkable CEO keeps building," but the stock can't keep up, he said. In fact, it's below MasterCard (MA) in terms of valuation. Cramer said he expects American Express to reach $72 by the end of 2007 as it plays catch-up to MasterCard.

First of all, everything in housing is going to be up against "easy comparisons" during the second half of the year, Cramer said. But despite that, Caterpillar has more to do with infrastructure in the Middle East tar sands and the digging out of coal and petrochemical refineries in Dubai than it has to do with homebuilders. Caterpillar, he predicts, should reach $90 by year-end. The stock closed Tuesday at $75.51.

Cramer said he believes that Citigroup (C) has potential upside despite the company's leadership
