“Shareholders have a residual claim on a firm’s assets and earnings, meaning they get what’s left after all other claimants—employees and their pension funds, suppliers, tax-collecting governments, debt holders, and preferred shareholders (if any exist)—are paid. The value of their shares, therefore, is the discounted value of all future cash flows minus those payments. Since the future is unknowable, potential shareholders must estimate what that cash flow will be; their collective expectations about the future determine the stock price. Any shareholders who expect that the discounted value of future equity earnings of the company will be less than the current price will sell their stock. Any potential shareholders who expect that the discounted future value will exceed the current price will buy stock. This means that shareholder value has almost nothing to do with the present. Indeed, present earnings tend to be a small fraction of the value of common shares. Over the past decade, the average yearly price-earnings multiple for the S&P 500 has been 22x, meaning that current earnings represent less than 5 percent of stock prices.”
