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 .
Note that some finance and economic theories assume that market participants can borrow at the risk-free rate; in practice, very few (if any) borrowers have access to finance at the risk free rate. The risk-free rate of return is the key input into cost of capital calculations such as those performed using the capital asset pricing model. The ...
Key. ER: Expected return on a specific asset RFR: Risk-free rate, typically the return on a Treasury security Beta: The volatility of the investment MR: The return on a comparable market index To ...
The price paid must ensure that the market portfolio's risk / return characteristics improve when the asset is added to it. The CAPM is a model that derives the theoretical required expected return (i.e., discount rate) for an asset in a market, given the risk-free rate available to investors and the risk of the market as a whole. The CAPM is ...
The consumption-based capital asset pricing model (CCAPM) is a model of the determination of expected (i.e. required) return on an investment. The foundations of this concept were laid by the research of Robert Lucas (1978) and Douglas Breeden (1979). The model is a generalization of the capital asset pricing model (CAPM). While the CAPM is ...
In finance, Jensen's alpha [1] (or Jensen's Performance Index, ex-post alpha) is used to determine the abnormal return of a security or portfolio of securities over the theoretical expected return. It is a version of the standard alpha based on a theoretical performance instead of a market index . The security could be any asset, such as stocks ...
(R m – R f) is the risk premium of market assets over risk free assets. The risk free rate is the yield on long term bonds in the particular market, such as government bonds. An alternative to the estimation of the required return by the capital asset pricing model as above, is the use of the Fama–French three-factor model.
The capital asset pricing model (CAPM) provides one method of determining a discount rate in business valuation. The CAPM originated from the Nobel Prize-winning studies of Harry Markowitz, James Tobin, and William Sharpe. The method derives the discount rate by adding risk premium to the risk-free rate. The risk premium is derived by ...
