The Capital Asset Pricing Model (CAPM): What Is It? How Does It Work? And Does It Work Effectively? In 1960‚ a doctoral candidate in economics at the University of California‚ Los Angeles by the name of William F. Sharpe needed a dissertation topic. After reading a 1952 paper on portfolio theory by Harry Markowitz entitled Portfolio Selection‚ Sharpe had found his idea. Markowitz ’s paper presented the notion of an "efficient frontier" of optimal investment that advocated a diversified portfolio

CAPM is a model which enables investors to determine the expected return from a risky security. It observes the relationship between the risk of an asset (Mobil Oil) and its return. The model uses Beta as the main measure of risk. This model works under the following situations: • In a perfectively competitive market where they are many price-takers’ investors‚ who have a small market share each. • Investors behaviour is myopic • Also investments included in the model are publicly

Derivation of the CAPM We know from Markowtiz’ framework concerning two-fund separation that each investor will have a utility-maximizing portfolio that is a combination of the risk free asset and the tangency portfolio. If all investors see the same capital allocation line‚ they will all have the same linear efficient set called the Capital Market Line (CML). This forms a linear relationship between expected return of the portfolio and the standard deviation. If market equilibrium is to exist we

stock price will decrease and it results in a lower PE ratio.It may mislead some of investors to buy the stock . Apart from PE ratio‚ Dividend Discount Model (DDM) will be a better way to value the stock price. The DDM model seeks to value a stock by using predicted dividends and discounting them back to their present value. The Formula of DDM is Dividend per share over discount rate minus dividend growth rate. Value of Stock = D1 R- G Where‚ • DPS (1) = Dividends per

of this paper will derive the validity of the Fama and French (FF) model and the efficiency of the Capital Asset Pricing Model (CAPM). The comparison of the Fama and French Model and CAPM (Sharpe‚ 1964 & Lintner‚ 1965) uses real time data of stock market to practise its efficacy. The implication of the function in realistic conditions would justify the utility of the CAPM theory. The theory suggests that the expected return demanded by investors on a risky asset depends on the risk-free rate of interest

asset pricing model (CAPM) for researchers and practitioners. Markowitz (1952) argued that investors should be concerned with holding efficient portfolios‚ that is‚ a portfolio offering the highest expected return for each level of risk. Sharpe (1964) and Lintner (1965) took Markowitz’s work one step further to develop the CAPM to explain the relationship between systematic risk and expected return in financial markets. The CAPM is denoted by the following equation: The CAPM is used to determine

In a world where non-linearity and randomness are the norm‚ the capital asset pricing model (CAPM) is widely accepted despite it being a linear model‚ and this is probably due to the simplicity of the model and its pre-computer age birth (see equation below). A well recognized and utilized metric in finance is beta (β)‚ which is the slope in the linear CAPM. To derive β one simply plots the returns (capital gains plus dividend yields) of an individual stock (y-axis) against the returns of a well
