BlackBerry shares tumble
Shares of BlackBerry slipped yesterday after its former co-CEO, Jim Balsillie, disclosed that he had sold his once-sizable stake in the embattled smartphone maker.
In a regulatory filling yesterday, Balsillie said that by the end of last year he had sold his entire stake in the company. Balsillie, who resigned a year ago, owned about 26.8million shares, or a 5% stake in the company, as of December 31 2011. BlackBerry shares were down 3.4% at $13.52 in early trading.
