Asha is their Symbian based quasi-smartphone linup (also runs angry birds). It is a huge hit in developing nations (2nd world, not 3rd). Asha was in development long before Nokia partnered with Microsoft. Nokia released it because Asha devices can still be sold at lower price points than WP7 devices... and of course because WP7 devices are stuck in 2011.
Asha probably won't go away completely until WP8 gets down to Asha price levels.
I once thought about stocks this way too, but that isn't how stocks work. Stock prices aren't based on a companies current financial situation, but on where the majority of investors expect a company to be headed.
If investors are expecting a loss of $1 billion, that expectation is priced into the stocks value. Should the company end up reporting "only" $500 million in losses, the stocks value will rise as a result. That is pretty much what happened here, or so analysts say (enjoy only with a healthy serving of salt)...
I think the NOK bears blinked, and already have or are at least contemplating becoming bulls.
