Lightning Round: Best performing stock in the S&P
It's that time again! The Lightning Round bell has rung, and Jim Cramer gives his take on a few favorite audience stocks:

CVR Refining : "I've been looking at that stock, and it's one of the ones that has that troublesome yield. a 14 or 15 percent yield means that it is a red flag, which means I can't recommend it."

Horizon Pharmaceuticals : "We like all the pain plays, we think there is room for all of them. But you have to understand it is a very speculative situation...as long as people recognize you have to be playing with your mad money, I'm okay with it."

Seadrill : "I don't know how much lower Seadrill can go. It's been just a disaster, along with all of the others. That said, there are a lot of people who know that if oil were to drop back to $42, that stock would go to $8. At this point you have endured enough pain. You do not need to sell it yet, but know that the downside might not be complete if oil goes down to $42."

Southwest Airlines : "Best performing stock in the . Do I think it could repeat? I don't know. It's a great stock, a great airline. I listened to the Delta call and Delta is real good. I bet Southwest is really good tomorrow, I like it."

Rice Energy : "I got enough oil companies with really good dividends and have great prospects, so I don't need to be in Rice. If I had to be in one that is really down and out that fits the Rice category, I would probably be in Carrizo or maybe in Cimarex ."

Greenbrier Companies : "It is too volatile for me, as is Trinity . They just reported a fantastic quarter, but I do think that there will be fewer cars ordered because I think that the railroad part of the oil business is going to be slowed down...scale out of it over time."

Old Dominion Freight Line : "People feel that the trucking companies are not having a good quarter. People also feel that they are not benefiting because diesel fuel has not fallen as fast as regular gasoline. I think Old Dominion is fine, and that owning the truckers is not a bad deal."

Deckers Outdoor Corp : "My feeling on Deckers is that you own it long-term because Angel Martinez is maybe one of the smartest people in the footwear business. I want to own that stock. Am I saying the quarter is good? No, I'm saying that you want the long-term value of Deckers."

Castlight Health : "No, that came public during a time when a whole lot of other companies came public. It was a real jam up, I'm disappointed and expensive. If you want cost effective benefits, it's not exactly the same kind of industry but I've been recommending TriNet . That is the one that I want to use."

Sprint : "There's a lot of talk about a Sprint and a Google tie up, talk with a Sprint and T-Mobile tie up with Google. All this is talk, all of it is rumor. I think you have to hold on to Sprint for the long-term because it's too low to sell at $4 and they've got a big backer. I think they'll be okay."

Integrated Device Technology : "I hear good things about it, but my favorite in that sector is Cypress and I still like Intel after that quarter. But Cypress to me represents the best value and so does Skyworks . I think those are better plays."
