Jim Cramer Gives His Opinion on Kellogg, Schlumberger And Southwest Airlines

On CNBC's "Mad Money", Jim Cramer said he wouldn't sell Kellogg Company K because it has a good yield and it is doing fine. It's not a growth stock, but he would keep it for diversification purposes.

Schlumberger Limited. SLB is too cheap, thinks Cramer. He explained that it's trading at the same price level as it was trading when crude oil was trading at $25.

Southwest Airlines Co LUV keeps reporting better quarters and Warren Buffett just bought more of the stock. Cramer thinks it's a very inexpensive stock. He added that it has historically been more expensive than the rest of the sector. The airlines sector has moved up and Southwest Airlines should move up too, believes Cramer.
