Cramer: One of the most heavily shorted stocks in the market today

It's that time again! Jim Cramer rang the lightning round bell, which means he gave his take on caller favorite stocks at rapid speed:

Lumber Liquidators: "Keep looking but don't go in there, because we are going to Lowe's, LOW."

Western Digital: "Keep wondering, but don't pull the trigger. Why? Because that group is just really, really difficult to own. That may be hte best of a bad lot. I prefer to see you in NVIDIA."

A.O. Smith Corp: "That is a winner my friend. Heating, ventilation and air conditioning. I got this guy James Gentile who writes at He has turned me on to this and many of the other American industrials."

Micron Technology: "I think Micron is still part of a big dead cat bounce. Why do I say that? Because Applied Materials reported a big buyback after the close that could drive the semiconductor group again. I prefer NVIDIA and in that particular segment I like Lam Research, LRCX."

Baxalta Inc: "We are ringing the register because that means it's done. Baxalta is done. And congratulations if you did it."

KEYW Holding Corp: "I'm worried about cybersecurity stocks after Palo Alto can't maintain the altitude. Let me look at this one individually, but the group has concerned me ever since the Palo Alto. And the fact that Cyberark, which makes money has been going down despite the fact that it's got very important proprietary software."

Integrated Device Technology Inc: "The last time the CEO came on the show, I thought he acquitted himself well. The previous quarter had been bad, but then they came back. I think that that was just a one-off situation."

Cal-Maine Foods Inc: "This is an egg company. This is very surprising because this is one of the top five most heavily shorted stocks in the market today. Isn't that amazing? This is a battlefield stock. I don't play on battlegrounds, I say don't buy."

Metlife Inc: "No, we have two insurers we recommend. We recommend Travelers and most important we think Chubb is the best one to buy."

Chemours Company: "We caught a very big trade in Chemours and then we said take it off the table. And then subsequently, Andrew Left [Citron Research] has been saying some negative things about it. Andrew does a lot of work and I've got to tell you, I don't wan to be on the other side of his trade."
