I have been making money shorting RIMM almost every day. BB10 is already priced in. It's the reason it ran up from $7 to $18, but you see how it has fallen back down. I hope it spikes tomorrow, so I can short it again.
BB10 is the last gasp of a dying company. There are so many phones out now, and so much competition, that it will be hard for them to catch up. Impossible, really, IMO.
