2 Investor Objectives 2.1. Measuring Investor Returns We understand that firms should attempt to maximize investor wealth. But‚ while we now have a strategic goal‚ we have a little way to go before we can turn it into an action plan. Companies generate uncertain cash flows over very long time horizons; we need a way of turning these risky income streams into equivalent quantities of hard cash. We will do this in two stages. We start with a careful discussion of interest rates‚ which will enable

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

Nature of Board Level decisions and the contribution of the finance director The performance of any organization‚ may it be for profit or not for profit‚ heavily depends on the decisions that are made by the management of the organization. It is worth noting that decisions made in the organization differ greatly‚ depending on the position of those involved in making those decisions. The board is one body that plays a crucial role in determining the future of an organization‚ based on the nature

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

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

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
