Lightning Round: This group cannot be bought

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:

J.C. Penney: "I think that the retailers that are working are TJX, Ross Stores, Dollar Tree and Dollar General. And I kind of don't want to go beyond that group right now."

Dynavax Technologies: "The stock is up so much today. No, I'm going to say you have to wait for that thing to go down. And I think it will come down, because the drug stocks have had too big a run here in the last two days."

AK Steel: "No, I think it has moved up enough. The only steel company that I am recommending is Nucor, which pre-announced a bad number and continued to go higher."

Boeing: "My charitable trust owns Lockheed Martin, I am still waiting for clarity on the accounting issues that they are having. And I don't have to worry about the clarity for Lockheed Martin."

Lannett: "No, these specialty pharmaceutical companies cannot be bought here. I don't want you in them."
