Stop Trading!: Buy Owens Corning

Cramer reiterated his support for alternative energy stocks on Tuesday’s Stop Trading!, saying he likes to look for the less-than-obvious plays that win off the fundamental growth of industries like solar and wind power.

Take Owens Corning , the company best known for its home insulation composites. Insulation is actually a play unto itself, Cramer said, because properly insulated homes can cut energy production by 40%. But OC is also a winner because it makes composite materials for wind turbines. You wouldn’t know that unless you did a little bit of homework, but OC is as much an alternative energy stockas it is a building and construction stock.

Briefly touching the media sector, Cramer said cable is the best play right now. His favorite stock there is Discovery Holdings .

Jim's charitable trust owns Discovery Holdings.
