Jim Cramer has three growth stocks he believes you should own for 2007, even if you hate risk, he said during his "Mad Money" TV show Thursday. "There's room in anyone's portfolio for a good growth stock," he said. Cramer opened with his No. 3 growth stock of the year: Cisco Systems ( CSCO). After spending years as a "dead-end" stock, Cisco has finally come back, Cramer said. And even though it is up big since he recommended it on Aug. 8, Cramer said he expects it to "keep running" the whole year, as it has turned itself into a "consumer-oriented tech stock." "The Cisco of today is not the Cisco of yesterday," he said. It's no longer a networking backbone play but has penetrated homes by becoming a major competitor in the triple play (video/phone/Internet) market, Cramer said. After spending some time in the "wilderness," Cisco is back as the No. 3 growth stock for 2007, Cramer said.
