2 5.2 Van Horne and Wachowicz, Fundamentals of Financial Management, 13th edition. © Pearson Education Limited Created by Gregory Kuhlemeyer. After studying Chapter 5, you should be able to: 1. Understand the relationship (or trade-off) between risk and return. 2. Define risk and return and show how to measure them by calculating expected return, standard deviation, and coefficient of variation. 3. Discuss the different types of investor attitudes toward risk. 4. Explain risk and return in a portfolio context, and distinguish between individual security and portfolio risk. 5. Distinguish between avoidable (unsystematic) risk and unavoidable (systematic) risk and explain how proper diversification can eliminate one of these risks. 6. Define and explain the capital-asset pricing model (CAPM), beta, and the characteristic line. 7. Calculate a required rate of return using the capital-asset pricing model (CAPM). 8. Demonstrate how the Security Market Line (SML) can be used to describe this relationship between expected rate of return and systematic risk. 9. Explain what is meant by an efficient financial market and describe the three levels (or forms) of market efficiency.

Return Example $10 $9.50 $1 dividend The stock price for Stock A was $10 per share 1 year ago. The stock is currently trading at $9.50 per share and shareholders just received a $1 dividend. What return was earned over the past year?

Defining Risk What rate of return do you expect on your investment (savings) this year? What rate will you actually earn? Does it matter if it is a bank CD or a share of stock? What rate of return do you expect on your investment (savings) this year? What rate will you actually earn? Does it matter if it is a bank CD or a share of stock? The variability of returns from those that are expected.

R = ( R i )( P i ) R is the expected return for the asset, R i is the return for the i th possibility, P i is the probability of that return occurring, n is the total number of possibilities. R = ( R i )( P i ) R is the expected return for the asset, R i is the return for the i th possibility, P i is the probability of that return occurring, n is the total number of possibilities. n I = 1

You have the choice between (1) a guaranteed dollar reward or (2) a coin-flip gamble of $100,000 (50% chance) or $0 (50% chance). The expected value of the gamble is $50,000. Mary requires a guaranteed $25,000, or more, to call off the gamble. Raleigh is just as happy to take $50,000 or take the risky gamble. Shannon requires at least $52,000 to call off the gamble.
