Been asking around about possible stock plays on Hurricane Sandy, and so far I do not see big bets being placed — yet. But there are ideas floating around.

While this seems reminiscent of Hurricane Irene, which brought a lot of rain to the East Coast in August 2011, Irene was not a hurricane when it made landfall and only dumped a modest amount of rain (about two inches) on Manhattan. It was a relatively mild event for the city, and even for insurers.

Sandy, potentially, could be more serious, particularly for insurers.

Companies with exposure here include Hartford , Travelers , Chubb . The caveat: flooding is not covered by homeowner insurance policies.

Anything else? The obvious play is roofing repair, and here I have heard names like Owens Corning and Beacon Roofing Supply bandied about. Other companies that sell waterproofing and roofing systems include RPM International and WR Grace .

I have heard some talk about gasoline refiners n the path of the storm (Philadelphia/Delaware/New Jersey) possibly being shut for several days. However, most of these refineries are privately owned.

Power failures (widespread with Irene) might impact electric utilitieslike Exelon , FirstEnergy , Pepco and PPL .

It might provide a lift to restaurants that do a big delivery business, like Papa John's or Domino's . But I am not seeing big volume in any of them.
