Shares of Canadian tech company BlackBerry (BBRY)  rose Tuesday, one day after it announced it is switching some of its focus from cell phones to self-driving cars and after the release of its quarterly earnings results. The company topped analysts' bottom-line expectations while also raising its full-year forecast. BlackBerry reported quarterly earnings of 2 cents per share, ahead of analysts' expectation of a 1 cent loss. However, revenue for the period fell to $289 million from $548 million a year ago, missing the Wall Street consensus estimate of $331.9 million. The company announced it is investing $75 million in a new autonomous vehicle testing hub in Ottawa that the company expects to start bringing in revenue in 2018.
