Jim Cramer's 'Stop Trading!': Buy Apple

Buy Apple AAPL, Jim Cramer said on CNBC's "Stop Trading!" segment Monday.

Cramer said that there is a "grudging recognition" in the market, especially after Nokia's NOK cautious guidance, that the iPhone will continue to win among smartphones. He said the iPhone is "huge, and when we get the next iteration ... it's going to be game, set, match." He also remarked that "there's no stock for sale. They keep buying it up."

Cramer also said that a new Mac product, Conversation, will bring Apple to the forefront of instant messaging. He said the product will be similar to the iPod in its impact. "The analysts don't see it because the analysts don't use it," he said. "I think this is a gigantic product."

Of smartphone rival Research In Motion RIMM, Cramer said, "We did get a great quarter. ... If Research In Motion reported that quarter today, it'd be at $150."

Pharmaceutical company Merck MRK gave a "great conference call," Cramer said. He said that the weekly scripts for Vytorin were the key metric for the company.
