Orange County has a new group of market cap leaders. None of the top five in market cap on the OC Business Journal’s list in March have stayed in the same ranking.
Broadcom Corp., Irvine, has moved up from No. 3 to become the county’s most highly valued public company, with its market cap tripling since March to a current value of about $17.9 billion. Next is Conexant Systems Inc., Newport Beach, with a market cap of about $12.4 billion. Irvine-based Allergan Inc. remains on the list, but has slipped from No. 2 to No. 3 in value, while Costa Mesa-based QLogic Corp. is now No. 4, followed by its next-door neighbor and former parent, Emulex Corp.
