Lightning Round: Time for Lumber Liquidators?

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:

Puma Biotechnology: "It got a very important upgrade today by JPMorgan and because of the jam up in all of these things that have been going on, I only got the read that they thought it was too cheap. I've got to do more work than just give you that."

Ross Stores: "I've got to say hold. Why? Because I did not like that last quarter versus TJX which had a much better quarter, or Ulta which reported tonight that I really like."

Mannkind Corp: "The proof is in the pudding. We haven't seen the big sales bump yet. If we see a big sales bump, then I think there is going to be time. But we haven't seen it yet."

Vornado Realty Trust: "I think those guys are very, very smart. I like them and I've got to tell you historically Steven Roth [CEO] is a guy you want to bank on. I think it's low and it's probably right. Let me also throw in Federal Realty and Ventas for three real estate investment trusts that I like."

Lumber Liquidators: "I understand the desire, and I understand they got that compliance officer and they can turn around, and housing is getting better. But you know, that one's too deep in the woods for me. I'm a Home Depot guy, and I know it might not go up as much as Lumber Liquidators but I want to sleep at night."

Yahoo: "I think you're in good shape. It's been an up and down stock, and obviously it trades with Alibaba. The good news is that it's kind of reflecting no value other than Alibaba, even if they can't do the tax spin right. So I think you're okay."

AMN Healthcare Services: "Healthcare staffing is terrific. And may I just say that Susan Salka [CEO] whom we have had on many times, is an unheralded terrific CEO who is really created tremendous value."
