Obviously it is going down: the financial analysts know that this is a long-term strategy so for the short-term it has to be negative: Symbian will be gradually out, that is clearly a even larger than anticipated decline in its market share for 2011. Then in the long term, this is risky (and risk has to be paid by lower share price) because will Microsoft succed in being a leader in this market? And another risk is the fact that profitability is expected to be down as the OS is no longer Nokia but a royalty to Microsoft. What Nokia gain is still unclear. So the market is pricing down the company. It will be even worst if S&P is pushing down the note.
