Bloomberg – BlackBerry maker Research In Motion Ltd.’s stock has become twice as volatile as rivals’ around earnings announcements as investors look for evidence the company will keep pace with Apple Inc. and Google Inc.
RIM, which reports fiscal first-quarter profit tomorrow, rose or fell an average of 14 percent the day after earnings over the past eight quarters. That’s more than three times Apple’s average swing of 4.2 percent and above the 8.9 percent of Motorola Inc., which makes mobile phones that run on Google’s Android software.
