Cramer's 'Mad Money' Recap: The Fab Four of Tech

Further, although there have been sites similar to Amazon's, the company is one of a kind, he said. It "has the mechanics to dominate for years" and is a double threat as a tech and retailer. Growth drives a company, and Amazon, Cramer said, is full of growth.

Apple, on the other hand, is a bit more complicated. "I wouldn't buy it now," he said. Instead Cramer advised selling some Apple on its way up and buying it back after the iPhone launch, which is set for June 29.

Apple, he said, owns the MP3 player market with its iPod product, and now it's getting into phones -- a genius move. "It's an aspirational brand," which means the sky's the limit for the stock, Cramer added.

He called Research In Motion, Amazon, Google and Apple all "gigantic names that are so good they can't be competed with anymore."

Am I Diversified?

During Cramer's "Am I Diversified?" game, the first player called out the following five stocks: Bank of America (BAC Quote), Exxon Mobil (XOM Quote), Duke Energy (DUK Quote), FuelCell Energy (FCEL Quote) and Altria (MO Quote), a stock Cramer owns for his charitable trust.

Cramer called the portfolio "perfect" and blessed it as diversified.

Cramer's next caller asked if he was diversified with these five plays: Apple (AAPL Quote), Schering-Plough (SGP Quote) Devon Energy (DVN Quote), Target (TGT Quote) and Yahoo!

Cramer said the group of stocks was "picture perfect."
