They shouldn't be concerned with the share price on any given day, but they should be concerned with the share price over an extended period of time as that is how the company is valued and how the owners of the company (i.e., you and I and the rest of the common shareholders) receive 'value'. We have not received much value, we have received ... oh, never mind, don't want to get deleted again ;)
Also, they can't just tend to business by doing what they have always done, that's what got us into this mess to begin with. JMHO
