Jefferies analyst Peter Misek has a "buy" rating on the stock and a $22 price target. His bullish outlook is not based on a revival of BlackBerry's smartphone business, but on software, particularly the software to manage mobile devices.

Mark Sue, analyst with RBC Capital Markets, has a "market perform" rating on BlackBerry shares and said the stock is likely to remain range bound between $15 at the upper end and $8.50 at the lower end.
That may make it a stock for traders, Sue said.
