Jim Cramer told "RealMoney" radio show listeners Tuesday that he is always on the lookout for situations no one else thinks about in terms of making money, even a tragedy like the death of Dana Reeve. The 44-year-old widow of Christopher Reeve died of lung cancer late Monday, and Cramer believes that the company that finds a cure for the disease will win big. Genentech ( DNA) is the company that immediately comes to mind when he thinks about cancer treatments, including its treatment Evastin, which he called the "drug of last resort." But this isn't working if people are dying at age 44, he said. Instead, he said to take a look at a stock he has not recommended in three years, "a drug that may be the answer to lung cancer," and that's Pfizer ( PFE). The company has a 3.75% yield, meaning it sends you checks four times a year "while you're waiting for something good to happen," he said. He added that Pfizer's treatment ProMune is about to go into phase III clinical trial, the last phase before FDA approval. If this lung cancer drug works, it may be the best play against the disease. Cramer still sees money in the Internet, even though The Wall Street Journal ran a piece saying that Internet companies are going to have to ramp up spending to make money. Cramer said that he doesn't like traditional Internet plays, including Amazon.com ( AMZN), because he says it gives away too many of its services. He was also unenthusiastic about eBay ( EBAY), which recently bought phone company Skype, and Google ( GOOG), which he now says is too expensive. But he said it's possible to make money off of these companies as they're forced to spend more to do more. The equipment at every giant Internet company uses gear from Rackable Systems ( RACK), chips from Advanced Micro Devices ( AMD) and Akamai Technologies ( AKAM) to drive their traffic, he said.
