On CNBC’s "Mad Money Lightning Round," Jim Cramer said he can’t recommend Roblox Corp (NASDAQ:RBLX) as it is not making money.

The "Mad Money" host believes the metals have peaked, and therefore he can’t recommend Century Aluminum Company (NASDAQ:CENX).

Cramer said he needs to do some more research on Mitek Systems, Inc. (NASDAQ:MITK).

When asked about Li-Cycle Holdings Corp. (NYSE:LICY), Cramer said, "We’re dealing with a lot of peaking of a lot of different metals." He recommends staying away from the stock.

Cramer said that the CEO of Bausch Health Companies Inc. (NYSE:BHC) is doing a good job, but he brought Bausch and Lomb’s subsidiary to the market at a "very bad time. And that’s really, really crushed the stock."

When asked about Pioneer Natural Resources Company (NYSE:PXD), he said, "You’ve got to wait for it to come in, because it’s going to come in a little more and then we’re going to buy some more."
