Jim Balsillie, the former co-CEO of what was once called Research In Motion (now BlackBerry) apparently sold every single share of his ownership in the company. Balsillie once owned a total of 26.8 million shares, CNET noted.

Is he sour that he was asked to step down as the CEO? Or does he fear that BlackBerry is headed down the wrong path? It's hard to tell, but it's a bit concerning to see a major shareholder walk away so close to the launch of BlackBerry 10.

BlacKBerry's stock recently dropped more than 4 percent on news that Home Depot was ditching the company's BlackBerry platform and instead issuing more than 10,000 iPhones to its higher-level employees. Shares of BBRY are currently trading down 1.43 percent.
