Chances are that we are going to have a lot of hurricanes this year, and that can make investors some money, Jim Cramer said on his "RealMoney" radio show Tuesday. Some plays he believes could make people money during hurricane season are Nabors ( NBR), Southwestern Energy ( SWN) and Grey Wolf ( GW), he said. Although Cramer said he underestimated hurricane season last year, this year he believes natural gas is going to go up during the hurricane season. "Natural gas is a coiled spring," he said. Nabors, which Cramer owns for his charitable trust, Action Alerts PLUS , is one of the worst-performing stocks in its group, he said. Nabors is a coiled spring that is down 19% and should go up, he said. Southwestern is another stock down 19% for year that Cramer doesn't believe can go down much more. In addition, Grey Wolf, at $7, is half a point from its low, he said. Some might be temped to buy Chesapeake Energy ( CHK), but the problem with this is that it keeps issuing stock, Cramer said. Cramer advised viewers to stay flexible in their views regarding stocks. Flexibility is necessary to make money in the market, he said. For example, Cramer said last week he was worried about TD Ameritrade ( AMTD), which he owns for his charitable trust, Action Alerts PLUS , because it seemed to be going down every day. But then Bank of America came out with a research report about Ameritrade that insinuated a shortfall wasn't going to happen. Now, Cramer said he isn't worried about it anymore. "Had I cut and run when I was worried about it, I would have sold it at $13 and now it's at $14," he said, adding that he believes the stock is finished going down and wants to buy it. People need to be flexible, he reiterated. They can't cut and run. Cramer said he believes Ameritrade has bottomed. He stuck with the stock because the company was good. On the other hand, Seagate ( STX) is a company Cramer said does not have it right now, and he doesn't see a reason to stick with it.
