(Updates from 10:53 a.m. ET with closing information.) NEW YORK ( TheStreet) -- Here's what Jim Cramer had to say on CNBC's "Squawk on the Street" Friday. Williams Partners ( WPZ) is downgraded by Credit Suisse to neutral from outperform, despite the apparent insurance coverage on its plant explosion from earlier this year. WPZ was unchanged at $51.60. Barclays likes Regeneron Pharmaceuticals ( REGN). Cramer says it's been one of the strongest stocks of the year and adds, "I would not sell it here." REGN fell 4.1% to $224.88. Topeka Capital upgrades Facebook ( FB), and Cramer says it's positive news. He also says, however, that he doesn't expect the stock "to take off today" because it's had a terrible quarter and year. FB was up 1% to $24.88. Biogen ( BIIB) is an end-of-the-quarter "gift," according to Cramer, who points to the better-than-expected results from the company's MS treatment trials. BIIB was 3.1% higher at $215.20. Goldman Sachs added Unilever PLC ( UL) to its conviction buy list and Cramer says he completely agrees with the call. UL was unchanged at $40.45. KB Homes ( KBH) is a good company, but increased mortgage rates are going to weigh on the stock price, Cramer says. KB Homes was flat at $19.63.
