e. Estimated value (
) is the present value of the expected future cash flows. The market
price (P0) is the price at which an asset can be sold.
f. The required rate of return on common stock, denoted by rs, is the minimum acceptable
rate of return considering both its riskiness and the returns available on other
investments. The expected rate of return, denoted by ^
rs, is the rate of return expected
on a stockn given its current price and expected future cash flows. If the stock is in
equilibrium, the required rate of return will equal the expected rate of return. The
realized (actual) rate of return, denoted by ¯rs, is the rate of return that was actually
realized at the end of some holding period. Although expected and required rates of
return must always be positive, realized rates of return over some periods may be
negative.
h. Preferred stock is a hybrid—it is similar to bonds in some respects and to common stock
in other respects. Preferred dividends are similar to interest payments on bonds in that
they are fixed in amount and generally must be paid before common stock dividends
can be paid. If the preferred dividend is not earned, the directors can omit it without
throwing the company into bankruptcy. So, although preferred stock has a fixed
payment like bonds, a failure to make this payment will not lead to bankruptcy. Most
preferred stocks entitle their owners to regular fixed dividend payments.
