Cramer's lightning round: I am OK with Moderna
Karyopharm Therapeutics : "Nothing special, sir. Honestly, nothing special. I mean, look, [Bristol Myers Squibb] has unbelievable stuff against cancer, and its stock can't get out of its own way, so what does that say?"

Iron Mountain Inc. : "Iron Mountain, why did people not like Iron Mountain? It's unbelievable. The dividend's got growth. I think you're spot on. I'm liking it."

Moderna : "Moderna, yeah, they crushed it. I did like it at $18, $19. OK, here's the issue with Moderna: You've got to buy calls, not common stock, because the thing is just trading like a banshee. But I believe that [CEO Stephane Bancel] has cancer vaccines next and now he has the money to do the trials, so I am OK with Moderna."

Nvidia : "Congratulations to [CEO Jensen Huang], winning the Noyce Award for the best [semiconductor] guy of the year."
