Board Member/Director leaves... and what this signals:
[1] Employees Confused.
[2] Investors are going to really pissed off.
[3] Stock is most likely going to continue to fall. (The signalling from this step down is huge).
[4] It hints at possibility that the directors have had something to hide; something has been discovered; they have been secretly pushed out; or they have found out that something unethical has been going on in higher management and want to distance themselves from the company. Put another way, jumping out of a company when you aren't even pushed, when you are massively vested in it's success pretty much signals to everyone that Groupon is a sinking ship.
If they haven't filed bankruptcy by 2013 I'd be mightily impressed!
I can't wait to hear what Rocky Agrawal has to say about this.
