>> Former Oracle presidents Safra Catz and Mark Hurd will be co-CEOs. Ellison will be the Executive Chairman of Oracle's Board, and the company's CTO
I can see why the stock dove. Ellison appears unsure that either Safra or Mark has the stuff to run the company by appointing them both to do part of the former job of one man.
In a best case scenario (where this triumvirate works for a while) I wonder which one's Brutus and which one's Cassius, because I'm pretty sure I know who Caesar is here.
