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

Prothena Corp: "I think this stock's a good one, This is one of those stocks I've been looking at as being a great spec for the second half of 2015, and it's been a winner. I think it's going to stay a winner. I want to own Prothena."

Chesapeake Energy: "I think that this is actually not one of my favorites. I think that it's an expensive stock and the group is headed lower right now. I would be careful with this one."

Cigna Corporation: "It had a good gain... and then it just kept going higher and higher. I've got to tell you I think it can continue to go higher..This group is very hot. I would not touch that stock, I think it goes higher."

Six Flags: "Just hold it, and I saw FUN earlier today and that's another one I like...They're doing great, this is a good group to own."
