Lightning Round: It's linked to China & troubled

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

Trovagene: "I thought it was too small, but then saw the stock had spiked so much. Neonatal, non-invasive care, I mean come on! This is the kind of company that people are buying right now...I kind of like it, but it's up a lot."

Chesapeake Energy: "No. Come on, we have to play with a full deck! Don't buy."

Caterpillar Inc: "Caterpillar is troubled here, because it is too linked to China which I think is slowing down. However, I would pull the trigger at $82 or $83. At $86 I think you've only got a four point upside and I want more upside."

Solaredge Technology: "This company is working right here, it's like SUNE but not as good. I prefer SUNE to this one, but you have a winner in the solar space as opposed to the one I liked too much at the beginning, First Solar, but I think it can still make a comeback."
