(2) The intercept is known as Jensen’s alpha‚ which is a coefficient that is proportional to the excess return of a portfolio over its expected return‚ for its expected risk as measured by beta. Hence‚ alpha is determined by the fundamental values of the company in contrast to beta‚ which measures the return due to its volatility. If CAPM holds‚ by definition the intercept of all portfolios (Jensen’s alpha) are zero. Also note that‚ if the alpha is negative‚ then the portfolio underperforms

for the risk you are taking CAPM calculates the risk-adjusted discount rate with the risk-free rate‚ the market risk premium‚ and beta (mathematical formula): Return (R) = Rf + beta x (Rm - Rf) Rf is the rate of risk-free investments Beta - the risk of loss associated with your investments. Rm is the expected market return. (Rm-Rf) – market risk premium beta x (Rm - Rf) – risk premium of specific company Investments are good if the expected return from the investment equals/exceeds required

In order to diversify away the firm-specific part of returns thereby enhancing the precision of the beta estimates‚ the securities where grouped into portfolios. The findings of this article are not supportive of the theory’s basic statement that higher risk (beta) is associated with higher levels of return. The model does explain‚ however‚ excess returns and thus lends support to the linear structure of the CAPM equation. The CAPM’s

We choose 30year US tbill rate because most of the large firms‚ such as Midlands‚ usually use the longterm yield of the U.S Treasury bond to determine riskfree rate. Similarly‚ to estimate the cost of equity‚ we use the CAPM: re=rf+ beta*(EMRP). Beta for Miland is 1.25 base on commercially available database.After reviewing the recent research‚ Midland adopts an EMRP of 5%. The cost of debt is 6.6% while the cost of equity is 11.23% for Midland. Therefore‚ the wacc is 8.16% based on the

economy. Therefore‚ investments have similar risk if they have the same sensitivity to market risk‚ as measured by their beta with the market portfolio. So‚ the cost of capital of any investment opportunity equals the expected return of available investments with the same beta. This estimate is provided by the Security Market Line equation of the CAPM with states that‚ given the beta‚ of the investment opportunity‚ its cost of capital is Ri=rf+Bi*(E[Rmkt]-rf) In other words‚ investors will require

hypothetical world with many assumptions. The Sharp-Lintner-Black CAPM states that the expected return of any capital asset is proportional to its systematic risk measured by the beta. (Iqbal and Brooks‚ 2007). Based on some simplifying assumptions the CAPM is expressed as a linear function of a risk free rate‚ beta and the expected risk premium. An important quantity required for decisions on evaluating public and private funded projects is an appropriate cost of capital. This discount rate is
