- It's that time again! "Mad Money" host Jim Cramer rings the lightning round bell, which means he's giving his answers to callers' stock questions at rapid speed.
Tortoise Energy: "That group has been horrendous. They all started bottoming at the same time that oil bottomed and they're coming back. I would just hold onto it, but I don't know exactly what's in it because … it's kind of a holding company."
United Airlines: "I think United is a coiled spring, but you're going to have to deal with a couple real bad quarters. So I say put it on hold, you don't have to chase it."
Nvidia: "I say hold onto Nvidia."
Fastly: "I think Fastly – it had a decent quarter, not a great quarter."
JD.com: "JD had a great quarter … I'm starting to warm up to JD."
Disclosure: Cramer's charitable trust owns shares of Nvidia and Bristol-Myers Squibb.
