On CAPS, 81% of the 15 All-Star members who have rated Pluristem believe the stock will underperform the S&P 500 going forward.

One of those Fools, biotech expert zzlangerhans, tapped yesterday's 7% stock price spike as particularly unsustainable:

Wow, Pluristem received approval in Germany! Approval to run a phase II trial there, that is. Pluristem CEO seems to be aware that issuing any PR with the word "approval" somewhere in it is good for a momentary 10% spike in share price. Someone should do a study to determine the correlation between these types of announcements and the lockup expiration dates for their dilutive financings.
