whats really behind this selloff?
You must (and we know you are) be joking... Its called a 'VOTE of NO Confidence' for Yaki Yanny & Zami Aberman, CO-CEO's of Pluristem.
TOO many beyond the 'safe harbor' statements and claims in the last 18 months not to deliver something, even a good rumor, to drive the shareprice into growth territory.
It's really that simple, don't over think it.
