- It's that time again! "Mad Money" host Jim Cramer rang the lightning round bell, which means he gave his take on callers' favorite stocks at rapid speed.
Mallinckrodt Plc.: "Sell, sell, sell. They paid too much for Acthar. I don't know why they did that. It was kind of a nutty thing to do. We're going to say no."
Alteryx Inc.: "I want you to let it run. I just hear nothing but good things about that. It's a small-cap stock that's going to the big time. Keep it."
Charles River Laboratories Intl. Inc.: "People thought the quarter wasn't that good. We should get [CEO] Jim Foster back on. I thought the quarter was OK. This is like Idexx Labs and like Henry Schein. Periodically, you get a quarter and people think it's not that great, but I like that company."
GoPro Inc.: "I thought GoPro would have a better quarter. I still think it might be OK, but boy, they did throw cold water on the whole darned situation in that last conference call."
