Two Reasons Why BlackBerry Stock Is Tanking Despite Mostly Positive Reviews

Despite mostly positive reviews for its new flagship phone from the big gadget gurus, BlackBerry stock has tanked over the past couple days.

Bloomberg talked to a bunch of analysts, and they say there are two big reasons why:

• BlackBerry hasn't said when the phone will go on sale in the US.
• The phone will cost $149 or $199, much more than lots of Android phones, which cost $99, $49, or nothing.
