An estimation of the CAPM and the security market line (purple) for the Dow Jones Industrial Average over 3 years for monthly data. In finance, the capital asset pricing model (CAPM) is a model used to determine a theoretically appropriate required rate of return of an asset, to make decisions about adding assets to a well-diversified portfolio.
Mean-variance efficiency of the market portfolio is equivalent to the CAPM equation holding. This statement is a mathematical fact, requiring no model assumptions. Given a proxy for the market portfolio, testing the CAPM equation is equivalent to testing mean-variance efficiency of the portfolio.
FCFF is the free cash flow to the firm (essentially operating cash flow minus capital expenditures) as reduced for tax; WACC is the weighted average cost of capital, combining the cost of equity and the after-tax cost of debt; t is the time period; n is the number of time periods to "maturity" or exit; g is the sustainable growth rate at that point
CAPM assumes that investors are looking to maximize their return and that they can evaluate expected return and risk. It also assumes that investors have access to risk-free borrowing and lending.
The weighted average cost of capital (WACC) is the rate that a company is expected to pay on average to all its security holders to finance its assets. The WACC is commonly referred to as the firm's cost of capital. Importantly, it is dictated by the external market and not by management.
The same relationship as earlier described stating that the cost of equity rises with leverage, because the risk to equity rises, still holds. The formula, however, has implications for the difference with the WACC. Their second attempt on capital structure included taxes has identified that as the level of gearing increases by replacing equity ...
