Unformatted text preview: 8-1 Chapter 8 - Risk and Rates of Return Learning Objectives After reading this chapter, students should be able to: Define risk and calculate the expected rate of return, standard deviation, and coefficient of variation for a probability distribution. Specify how risk aversion influences required rates of return. Graph diversifiable risk and market risk; explain which of these is relevant to a well-diversified investor. State the basic proposition of the Capital Asset Pricing Model (CAPM) and explain how and why a portfolios risk may be reduced. Explain the significance of a stocks beta coefficient, and use the Security Market Line to calculate a stocks required rate of return. List changes in the market or within a firm that would cause the required rate of return on a firms stock to change. Identify concerns about beta and the CAPM. Explain the implications of risk and return for corporate managers and investors. 8-2 CHAPTER 8 Risk and Rates of Return Stand-alone risk Portfolio risk Risk & return: CAPM / SML 8-3 Investment returns The rate of return on an investment can be calculated as follows: (Amount received Amount invested) Return = ________________________ Amount invested For example, if $1,000 is invested and $1,100 is returned after one year, the rate of return for this investment is: ($1,100 - $1,000) / $1,000 = 10%. 8-4 What is investment risk? Two types of investment risk Stand-alone risk Portfolio risk Investment risk is related to the probability of earning a low or negative actual return. The greater the chance of lower than expected or negative returns, the riskier the investment. 8-5 Probability distributions A listing of all possible outcomes, and the probability of each occurrence. Can be shown graphically.
