When asked about Walmart Inc. (NYSE:WMT), he said, "Man, that stock goes down every day. You know why? Because it used to go up every day. I think this is a good level to start buying Walmart." He added that Costco Wholesale Corporation (NASDAQ:COST) is better.

Cramer said ImmunityBio, Inc. (NASDAQ:IBRX) is losing a lot of money. "It’s a company that if they don’t get the approval that you want, it could be dangerous. As long as you accept the risk, then I’m fine, but it’s a very risky stock," he noted.
