(Updates from 11:14 a.m. ET with closing information.) NEW YORK ( TheStreet) -- Here's what Jim Cramer had to say on CNBC's "Squawk On The Street" Monday: Cramer said he'd be careful with SBA Communications ( SBAC), as American Tower ( AMT) reports Tuesday and he's a fan of that company, not SBA. He said BlackRock's ( BLK) plans for a new copper ETF would be good for copper, and International Paper ( IP) remains a hot stock. SBAC ended Monday trading flat, BLK fell 1.8% and IP was down 2.8%. Cramer was also bullish on cloud computing play SAP ( SAP) as well as Zynga ( ZNGA) amid news that Nevada and possibly New Jersey may allow online gambling. His love continued for generic drug maker Perrigo ( PRGO), saying that a strong flu season is helping this company. SAP was down 1% but ZNGA jumped 7.5%. PRGO closed Monday up 1.1%.
