The context was a publicly-traded for-profit company, like most large members of the banking system. And for those companies, you are indeed given a fiduciary duty to maximize profits (See eBay v Newmark, http://www.delawarelitigation.com/uploads/file/int51%281%29.pdf http://www.delawarelitigation.com/uploads/file/int51%281%29....). So they can indeed be theoretically sued for failing to maximize shareholder value to the best of their ability as a fiduciary: negligence includes knowingly failing to take action that would increase shareholder value, not just destroying it. After all, the two actions are the same thing.
