Cramer: This stock could be in the crosshairs of politician tweets

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:

Cyberark: "I know the group has gotten high risk. I didn't like that downgrade, I think Cyberark is doing well. But I've got to tell you, I understand. The high priced earnings multiple stocks have not faired that well ... but Workday did go up last night. Maybe there's hope here."

Carrizo Oil & Gas: "I think Chip Johnson [CEO] has done a good job, but I like these companies that have just done deals that are good. I like Concho. I like Concho better than Carrizo, I've got to tell you. I think that one is ready to ride. I also like Occidental for those who like a dividend. That's owned by my trust."

Clovis Oncology: "It just had that very big spike on the good news, and I don't like to chase the spike. It's got priority review for a particular kind of ovarian cancer and I think that you had to be in it last week to be honest."

Gilead Sciences: "It's not best-of-breed because they have not reinvested successfully from all that money they got from Hep C. They need to do an acquisition or they need to split the company up. One or the other. I can't recommend it."

Horizon Pharma: "Keep your powder dry here ... this is the kind of company that could easily be in the crosshairs of a tweeting politician. It doesn't mean that I think that it should, but it could be."

Genesee & Wyoming Inc: "Genesee is to me a decent railroad. I would actually prefer KSU here more than that. And/or Union Pacific."
