Following my principal on ratio/value, I believed that NOK was under value and added some position at $3.80 yesterday. I was planning to add more if it continue going down. To my surprise, it shots up to $4.45 about 17%. It's given beyond my expectation.I can't deny this was a luck but I still believe that holding under value stocks is a way to go for conservative players like me.
I used the same approach and bought HPQ at $12 and today it's $16.28.
