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

The Capital Asset Pricing Model commonly known as CAPM defines the relationship between risk and the return for individual securities. CAPM was first published by William Sharpe in 1964. CAPM extended “Harry Markowitz’s portfolio theory” to include the notions of specific and systematic risk. CAPM is a very useful tool that has enabled financial analysts or the independent investors to evaluate the risk of a specific investment while at the same time setting a specific rate of return with respect

pricing model (CAPM) Using the Capital Asset Pricing Model‚ we need to keep three things in mind. 1 there is a basic reward for waiting‚ the risk free rate. 2 the greater the risk‚ the greater the expected reward. 3 there is a consisted trade off between risk and reward. In finance‚ It is used to determine a theoretically appropriate required rate of return of an asset‚ if that asset is to be added to an already well-diversified portfolio‚ given that asset’s non-diversifiable risk. The CAPM says that

This relationship serves two significant functions. First‚ it provides a benchmark rate of return for evaluating possible investments. Second‚ the model helps us to make an educated guess as to the expected return on asset that have not yet been traded in the marketplace. Although the CAPM is widely used because

CAPM CAPM provides a framework for measuring the systematic risk of an individual security and relate it to the systematic risk of a well-diversified portfolio. The risk of individual securities is measured by β (beta). Thus‚ the equation for security market line (SML) is: E(Rj) = Rf + [E(Rm) – Rf] βj (Equation 1) Where E(Rj) is the expected return on security j‚ Rf the risk-free rate of interest‚ Rm the expected return on the market portfolio and βj the undiversifiable risk of security

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
