Any CEO who doesn't care about the share price doesn't care about his shareholders. If thats the case; he needs to take the company private so that he doesn't get hunted by the shareholders. What's the point of being a publicly traded company if you don't have a good relationship with your shareholders? He can go to hell and F@##$% himself and no one cares if he's going private but as long he's a publicly traded company he has a fiduciary and ethical responsibilty to the shareholders. However, if he's a conman or a criminal like he already is, he doesnt care because he think no rules would apply to him.
He has yet to show a profit, although I don't think even that would make much of a difference in SP.
I honestly think it has EVERYTHING to do with his credibility! He seems not to realize he doesn't exist in a vacuum. The current SP is part of the cost He is paying for his management decisions of the past.
