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

IBM Case Study 1.) IBM advertises itself as a company that provides service and business solutions. It used to be positioned as a computer hardware company‚ but as more companies like HP and Dell began to pop up they were forced to move away from this image. I recently had the pleasure of speaking with an IBM sales person‚ and he said that they very much rely on the value of their products‚ rather than competing on price. IBM positions themselves as having better‚ but slightly more costly

I. Current Situation (1991-1993) 1. History of IBM: IBM is a multinational corporation that started its activities in 1911. But its origins can be traced back to 1890‚ during the height of the Industrial Revolution. It was first known as the Computing-Recording Company‚ and then in 1924‚ it took the name of International Business Machines. Nowadays‚ this multinational company is known as the ¡§Big Blue¡¨ 2.

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

1 Factor Models The Markowitz mean-variance framework requires having access to many parameters: If there are n risky assets‚ with rates of return ri ‚ i = 1‚ 2‚ . . . ‚ n‚ then we must know 2 all the n means (ri )‚ n variances (σi ) and n(n − 1)/2 covariances (σij ) for a total of 2n + n(n − 1)/2 parameters. If for example n = 100 we would need 4750 parameters‚ and if n = 1000 we would need 501‚ 500 parameters! At best we could try to estimate these‚ but how? In fact‚ it is easy to see

“Critically discuss whether the CAPM makes portfolio theory redundant.” Introduction This assignment will explore whether CAPM makes portfolio theory redundant. The following areas will be discussed; Stages involved‚ functions and roles‚ important components‚ formula of cap-M‚ positive and negative aspects of Cap-M‚ all while drawing to the conclusion to whether Cap-M makes portfolio theory redundant. (ref:2) Definition CAPM is defined as Capital asset pricing model. It is an economic theory

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
