The use of capital asset pricing model (capm) in investment appraisal for equity financed and levered firms.

CAPM and Investment Appraisal (All  Equity Firm)  • Expected return ERi on equity (calculated from the CAPM formula) is  (often) used as the discount rate in a DPV calculation to assess a  physical investment project for an all equity financed firm  • We use ERi because it reflects the riskiness of the firm’s new  investment project – provided the ‘new’ investment project has the  same ‘business risk’ characteristics as the firm’s existing project.     • This is because ERi reflects the return required by investors to hold this  share as part of their portfolio (of shares) to compensate them, for the  (beta‐) risk of the firm (i.e. due to covariance with the market return,  over the past).    Docsity.com CAPM and Investment Appraisal  (Levered Firm)  • What if the new project is so large it will radically alter the  debt equity mix, in the future ?   • How do we measure the equity return ER (then the WACC) to  be used as the discount rate ?    • (MM result : Equity holder requires higher return ERi as the  debt to equity ratio increases.)   • We calculate this ‘new’ equity return by using the ‘levered  beta’ in the CAPM equation as :    L(new) = U (1 + (1‐t))(B/S)new)  Docsity.com Variants of the CAPM Docsity.com Zero Beta CAPM  ER ERz M beta ER ERz M sigma Z Portfolio Z is not the minimum variance portfolio.
