A momentous thing happened on CNBC.com yesterday: Apple wasn't the top stock looked up by readers of the Web site. It was Bank of America.
For more than a year and a half Apple has been the ticker lookup champ. Before that, Citigroup—owing to its widely held status—was the usual winner. But in 2010 Apple started appearing at the top of the ticker list, usually on its earnings days and MacWorld events. Then, in 2011, it started regularly seesawing with Citigroup.
