It sounds like you have convinced yourself that its no longer worth being a shareholder/investor here. Good luck on your future investments.
And as it relates to future stock price performance; Amarantus still has enormous upside potential....its just a matter if you want to stay on the tracks or get out of the way (actually, I think Geralds advice is right on....). I dont know exactly how things will play out or if this company will ever be successful...but dont count it out just yet.
