I'm on a negative result on nokia but a vary good overall result of the year. If you only investing in one company, I doubt nokia is the right one. But if you go wide and buy stocks in let's say 50 companies you can easy buy stocks in companies where Noone believes in and buy more when the values goes down. When it turns you have a lot of shares and can capitilze on all the short term players. Sure you lose everything from time to time. But the main thing: follow your strategy if it's successfully and analyze you current position as often as you can and need.
