Mad Money Lightning Round OT: Cramer Is Bullish On FMC (AONE, PPO, FMC, TSO)

Jim Cramer said, in the segment of the show called Mad Money Lightning Round OT, that investors should stay cautious, because this is not an easy market. Instead of buying A123 Systems, Inc.

, he would buy Polypore International, Inc.

, because it is diversified, and you still get an exposure to electric batteries. A123 Systems, Inc.

spiked 4.73% today, and closed at $5.54. FMC Corporation

is a dramatically undervalued manufacturer that is worth a lot, thinks Cramer. He is a buyer of this stock. FMC Corporation (

) gained 0.89%, and closed at $84.60. Tesoro Corporation

will report a magnificent quarter, said Cramer. He believes that the refiners are peaking right now, and he also thinks that you should sell Tesoro Corporation (

) after it reports earnings. Tesoro Corporation (

) fell 0.46% today, and it closed at $26.13.
