Share prices no, because it depends on the future expectations of others who buy and sell shares every day.
Imagine you are part-owner of, say, a local landscaping business, and you're a passive investor, i.e., not part of its management. The managers of this business would be working for the owners, including you, and the managers' mandate would be to maximize business profits over time, a portion of which you would get as income in the form of annual dividends or distributions.
When you buy a share in an exchange-listed company like, say, Apple, you're a part-owner of Apple. Our legal framework (encompassing everything from federal and state laws to company bylaws) stipulates that the board of directors works for and represents the interests of shareholders like you, and that the company's executives work to maximize profits for the shareholders over time. Shareholders, including you, vote to elect the members of the board, who have a fiduciary obligation to act in the best interests of shareholders, including you.
However, when most people think about "maximizing profits" they think about it as maximizing share prices. In practice, executives of exchange-listed companies are "held accountable" (by the board) for share prices, generally under the assumption that present share prices are correlated with future profits.
