Derivative of the basic equilibrium market price of stock and its implications 11.3 Average earnings yield vs. current earnings yield method The market value of the firm, V, can be defined as: x V= k (11.1) where x is the total expected future earnings and k is the cost of capital, then cost of capital can be estimated from x k= V (11.2) Lintner (1963) derived the rule for the marginal cost-of-capital decision as: r Ye (11.3) where r = the marginal internal rate of return, Ye = Y0/P0 is the current earnings yield,Y0 is current earnings per share, and P0 is current price per share.. 11.4 Discounting cash-flow method P0 = d1 d , then K e = 1 + g p0 Ke - g (11.4), (11.5) Percentage change method gˆ 1 + gˆ 2 + gˆ 3 + gˆ 4 ˆ = g, 4 = earnings in year t, year (t -1), respectively, and X t - X t -1 , gˆ t = X t -1 where Xt, Xt-1 gˆ t is the estimate of the growth rate in period t.

These methods are (i) average earnings yield method, (ii) DCF method, (iii) WACC method, (iv) CAPM method, (v) M&M’s cross-section method, and (vi) Chase’s method. The interrelationship among different cost-of-capital estimation methods were explored in some detail. The relative advantages between different estimation methods were also indirectly explored. The six cost-of-capital estimation methods that were discussed in this chapter give managers enough background to choose the appropriate cost-of-capital estimation method for utilityregulation determination, capital-budgeting decisions, and financial planning and forecasting.
