I have pulled this information from my experience and analyzing many articles I read about NOK.
I am 80% certain that NOK will rise to $6 between Feb 28 - March 29 2013.
I would recommend to buy more NOK and HOLD. Buy July call option strike at $3. If my prediction is correct, your option investment if NOK rise above $5.38.
For example you buy call option on July 2013 strike at $3.00 for only $1.38. If NOK rise to $5.38 you will double your investment.
I would buy July 2013 and Jan 2014 option strike at $3 is a very good deal.
