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:

Chemours: "Holy cow, that thing is a bat out of hell! It has moved too much. The short-sellers are all over it, but I say ka-ching ka-ching."

Acuity Brands: "This one was considered to be a secular grower in an area where all people want is cyclical. It is not right to own right now."

Intuitive Surgical: "ISRG is going to be going down right now, because people feel the hospitals won't have enough money to be able to buy equipment because of the possibility of the repeal of the Affordable Care Act. So, we are not going to be able to touch ISRG at this very moment."

Synchrony Financial: "Synchrony is right here! Synchrony is right, and by the way Bruce Kamich, a special technician at RealMoney.com says that GE is finally ready to roll, too. Synchrony, off course is a spinoff of GE."

FireEye: "Yes but just do it on spec ... because the quarter didn't have it. Although I do like that new CEO. I sanction buying the stock under $15 but only for a trade because it's not my fave, and that group is getting hit."

Supernus Pharmaceuticals: "I liked it for the Parkinson's actually. So, my take is that this actually is a decent spec. I think it's a good spec, but remember, healthcare right now is all over the map."

Ariad Pharmaceuticals: "We have a pension to like these speculative oncology stocks, but let's not forget that drug stocks right now, they are being sacrificed to the alter of the cyclicals."
