Caterpillar (CAT): Cramer thinks the downgrade of CAT was mistaken, because it is not levered to housing, but to BRIC as well as the Middle East and Asia. He predicts machinery stocks are this era's growth stocks and will benefit form the weak dollar because of international exposure.

Crocs Inc. (CROX): People keep asking Cramer how long to hold CROX, and he suggests hanging on until the last firm rolls out coverage. "Once it's sponsored by everybody, then you've got to vamoose," he said.

Yum! Brands (YUM): Despite some yucky incidents, like the ecoli outbreak and rat infestation in a New York City KFC, YUM is up 11 points. "When I see it happen, I am supposed to stop shopping? Nobody else did." Cramer says the stock is "screaming higher" to $70.
