Cramer's lightning round: Hold onto Nvidia
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."

Nano Dimension : "If I want 3D print I'd be going to HPQ . … it's a crowded field."

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."

Viatris : "I think you should be in Bristol-Myers ."
