Coursework 3 - Case Study ExampleWith that stated, the expected return on this portfolio is halfway between the expected returns on the two undivided securities however, the standard deviation is less than halfway between the standard deviations on the two securities. Therefore, unless the director was very take chances averse, meaning he would look at this case, where he might choose to invest only in security A. However, if he were not risk averse he would invest in the portfolio rather than invest in the two securities separately (Gitman, 2009).Standard deviation is defined as the common statistical indicator of an assets risk it measures the dispersion around the expected value. This is other way that a firms risk and expected return directly affect its share price. Risk and return are the two key determinants of a firms value. It is broadly a financial managers responsibility to assess carefully the risk and return of exclusively major decisions. Managers use this to ensur e that the expected returns justify the level of risk that someone will introduce (Gitman, 2009.The definition of (CAPM) or capital asset pricing copy is the basic theory that links risk and return for all assets. We describe this race between the required return, r. The no diversifiable risk of the firm as it is measured by the beta coefficient b. This is important in finance because the moulding CAPM links non-diversifiable risk and return with all assets. Generally, there are five sections. The first deals with the beta coefficient, which is a measure of the non-diversifiable risk. The second section presents an equation of the model itself. The third section graphically describes the relationship between risk and return. The fourth section discusses the effects of changes in inflationary expectations and risk aversion on the relationship between risk and return and the fifth section offers some comments of the CAPM.The CAPM model in general relies on historical data. The beta s
