Lightning Round: Should have struck gold already

It's that time again! The Lightning Round bell has rung, and Jim Cramer gives his take on a few favorite audience stocks:

Dicerna Pharmaceuticals: "This company has been around for a while...I think it should have struck gold already by now. I'm on hold on this one."

Ziopharm Oncology: "This one is too much of a battleground. It's been up and down, and up and down. I have to say don't buy because the longs and shorts are going at it with this one."

Akamai Technologies: "This is a content delivery system, and I think it's terrific. We keep proliferating, and I think in all sorts of different ways it's a connectivity play. I like it."

Lion Biotechnologies: "I do like this one very much and I wish we hadn't missed a little bit of it, but this is one that comes in with the JUNO and the HALO and it works for me."

Antero Resources Corporation: "I think these guys came to the market at the wrong time, and paid too much for things. I'm going to stay away from that one."

Five Below: "I'm nervous about Five Below, and it feels a little bit more like an REI than it does for a stock that's down....we are going to stay away from Five Below when there are so many great companies like Ross Stores around. That's where I want you to go, and I know they're not totally comparable."
