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.
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 ...
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. Typically, then, financial modeling is understood to mean an exercise in either asset pricing or corporate finance, of a quantitative nature.
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 ...
Sharpe was one of the originators of the capital asset pricing model (CAPM). He created the Sharpe ratio for risk-adjusted investment performance analysis, and he contributed to the development of the binomial method for the valuation of options , the gradient method for asset allocation optimization, and returns-based style analysis for ...
Ke is the risk-adjusted, theoretical rate of return on a Company's invested excess capital obtained through external investments. Among other things, the value of Ke and the Cost of Debt (COD) [ 6 ] enables management to arbitrate different forms of short and long term financing for various types of expenditures.
Here’s how the capital asset pricing model works.
