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 firm's stock price from a current level

of Tk.20 to Tk.25 in six months and then to Tk.30 in five years, but another action would

probably keep the stock at Tk.20 for several years but then increase it to Tk. 40 in five years,

which action would be better? Can you think of some specific corporate actions that might

have these general tendencies?
