Cramer's lightning round: AMD is a buy 'right here, right now'
Martin Marietta Materials : "Well-run company. Doesn't need the stimulus, doesn't need the infrastructure package. Just needs for this country to stay on course. Might be a little rocky here, but I like it."

Bank of America : "We're saying that over the next four or five days, there could be some weakness in the market, but I agree that Bank of America is an excellent institution and if you think that rates ultimately will have to go up — which the Fed certainly said — Bank of America is going to go higher, so I am in favor of holding and then buying a couple days from now."

CRISPR Therapeutics : "Here's the problem with CRISPR, if they called it anything else other than CRISPR, people wouldn't be drawn to it, but people are so into CRISPR stuff they're like, 'Oh, let me buy this one.' I've got to tell you: I honestly would prefer to see you in Vertex, which has just got hammered, or Regeneron, where the news is very good."

Advanced Micro Devices : "May of last year it was at $52, now it's $80. Lisa Su is doing an amazing job. Here's what I think happens ultimately: I think when that Xilinx deal closes, that stock just soars. I'm urging you to buy it right here, right now."

AT&T : Not recommended
