In fact, McKechnie said he thinks the stock will be just about cut in half to $8 a share by year's end as the company's new BB10 smartphones come with a changed business model on top of strong competition from new Google Android devices and Apple iPhones.
Over at another one-time darling of the cellphone market, Nokia, it's been a tough year so far. But Stuart Jeffrey, telecommunications equipment analyst at Nomura, told CNBC he sees the stock rising about 30 percent to $4.40 a share by year end.
Jeffrey said those gains are likely to be driven by sequential growth of the company's new Microsoft Windows smartphones. But like BlackBerry, Nokia faces the same headwinds from Android devices and iPhones, he concluded.
