Cramer's lightning round: Roku should never have spiked so high

Key Points
  • 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.

Roku: "I don't think it should ever have spiked as high as it did. I think it's regarded as being a play on what I would call the cord cut, and that story's getting a little long in the tooth."

Hexo Corp: "That is the most speculative."

Rambus: "I'm going to tell you to buy Nvidia on the way down rather than that one."

Kroger: "I'd rather tell you wonderful things about Costco, which is I think crushing Kroger."
