NEW YORK (TheStreet) -- Here's what Jim Cramer had to say on CNBC's "Squawk on the Street" Tuesday.

Regeneron Pharmaceuticals
(REGN - Get Report) is off its morning highs but still positive after beating on top- and bottom-line earnings estimates. "People always want to sell it down, I don't know what the deal is," Cramer said. The company has a lot of products in its pipeline. REGN rose 7.4% to $326.52.

"I didn't like the number," Cramer said of Masco's (MAS - Get Report) earnings report. However, results were better than what investors had anticipated, therefore the stock is rallying. Home Depot (HD - Get Report) and Sherwin Williams (SHW - Get Report) are also upas a result. MAS was 3.8% to $22.53.

Rackspace Hosting's (RAX) CEO Lanham Napier suddenly resigned, causing Cramer to wonder, "What's going on?" The company beat revenue expectations and reported in-line earnings results. RAX dropped 17.7% to $33.20.

Pioneer Natural Resources (PXD - Get Report) beat on the top and bottom lines, but Cramer said the company "didn't raise the [oil] reserves" enough. As a result, he said he's "got to find out more" information. PXD was 3.4% lower at $180.66.

Morgan Stanley downgraded Alcatel-Lucent (ALU) to hold from buy. Cramer said investors think Alcatel-Lucent is taking market share from Cisco Systems (CSCO - Get Report), which reports earnings on Wednesday. Cramer wants to see Cisco's report. AKU fell 3.7% to $4.21.

Raymond James downgraded Lennar (LEN - Get Report) to buy from strong buy. Cramer said investors should "be careful" because the company has a lot of housing inventory, which could weigh on its pricing power should housing demand fail to come back strong. LEN fell 1% to $40.56.
