Cramer said Intuitive Surgical beat its numbers fair and square, and when a company beats every metric Wall Street is looking for, that's a company he wants to invest in.
McCallister said Humana, one of the largest players in the Medicare market, is taking full advantage of the changing demographics in the US. He noted the company reported a 69% jump in earnings in the past quarter and raised its guidance for 2008.
He said the company plans to grow through focused acquisitions and is not opposed to buying back shares if it's in the best interest of its shareholders.Asked about the upcoming election, McCallister said just about any Medicare reform plan will benefit providers such as Humana. Cramer told investors to buy Humana on any weakness.
