please answer all 3 of these questions in very detail.

1. Why is corporations primary financial goal shareholder wealth maximization, which translates to maximizing stock price? Why shouldnt their goal be profit maximization, revenue maximization, or cost minimization?
2. Should stockholder wealth maximization be thought of as a long-term or a short-term goal for example, if one action would probably increase the firms stock price from a current level of $20 to $25 in 6 months and then to $30 in 5 years but another action would probably keep the stock at $20 for several years but then increase it to $40 in 5 years, which action would be better? Can you think of some specific corporate actions that might have these general tendencies?
3. Is it better for a firms actual stock price in the market to be under, over, or equal to its intrinsic value? Would your answer be the same from the standpoints of both stockholders in general and a CEO who is about to exercise a million dollars in options and then retire?
