Lightning Round OT: 3M, Manitowoc and More

Manitowoc : This is an "interesting speculation" play, Cramer said.

American Superconductor : Don't buy, Cramer said. This company has exposure to alternative energy, which usually doesn't work when oil prices are low.

3M : 3M is a buy, Cramer said. He likes the 3.5% yield and called the company "overlooked" and "a great play on world recovery in 2010."

Excel Maritime Carriers :Nordic American Tanker continues to be Cramer's favorite stock in the shipping sector.
