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.
For the latter, various models have been developed, where the premium is (typically) calculated as a function of the asset's performance with reference to some macroeconomic variable – for example, the CAPM compares the asset's historical returns to the "overall market's"; see Capital asset pricing model § Asset-specific required return and ...
In financial economics, asset pricing refers to a formal treatment and development of two interrelated pricing principles, [1] [2] outlined below, together with the resultant models. There have been many models developed for different situations, but correspondingly, these stem from either general equilibrium asset pricing or rational asset ...
Financial modeling is the task of building an abstract representation (a model) of a real world financial situation. [1] This is a mathematical model designed to represent (a simplified version of) the performance of a financial asset or portfolio of a business, project, or any other investment.
Factor models are statistical models that attempt to explain complex phenomena using a small number of underlying causes or factors. [3] The traditional asset pricing model, known formally as the capital asset pricing model (CAPM) uses only one variable to compare the returns of a portfolio or stock with the returns of the market as a whole. In ...
The consumption-based capital asset pricing model (CCAPM) is a model of the determination of expected (i.e. required) return on an investment. [1] The foundations of this concept were laid by the research of Robert Lucas (1978) and Douglas Breeden (1979). [2] The model is a generalization of the capital asset pricing model (CAPM). While the ...
Security market line (SML) is the representation of the capital asset pricing model. It displays the expected rate of return of an individual security as a function of systematic, non-diversifiable risk. The risk of an individual risky security reflects the volatility of the return from the security rather than the return of the market ...
The capital asset pricing model, or CAPM, is prototypical. The Gordon Model , is a discounted cash flow model based on dividend returns and eventual capital return from the sale of the investment. The Bond Yield Plus Risk Premium (BYPRP), adds a subjective risk premium to the firm's long-term debt interest rate.
