Why? if you do not know why then you should not invest in NWBO ... but because all those who say they only want the best for nwbo and the stock price, time and time again time and time again, run a hype up on boards, twitter, facebook etc .. a classic pump and dump ...
people never learn it with this stock ...
and when the company has a communication strategy that is so bad and unprofessional then this happens .. again again
