Essay Questions

121. According to the CAPM, the expected return on a risky asset depends on three components.

Describe each component, and explain its role in determining expected return.

122. Draw the SML and plot asset C such that it has less risk than the market but plots above the

SML, and asset D such that it has more risk than the market and plots below the SML. (Be sure to indicate where the market portfolio is on your graph.) Explain how assets like C or D can plot as they do and explain why such pricing cannot persist in a market that is in equilibrium.

123. Why are some risks diversifiable and some nondiversifiable? Give an example of each.

124. We routinely assume that investors are risk-averse return-seekers; i.e., they like returns and dislike risk. If so, why do we contend that only systematic risk and not total risk is important?

125. In the first chapter, it was stated that financial managers should act to maximize shareholder wealth. Why are the efficient markets hypothesis (EMH), the CAPM, and the SML so important in the accomplishment of this objective?

126. Explain in words what beta is and why it is important.

127. A portfolio is made up of 75% of stock 1, and 25% of stock 2. Stock 1 has a variance of .08, and stock 2 has a variance of .035. The covariance between the stocks is -.001. Calculate both the variance and the standard deviation of the portfolio.

128. The diagram below represents an opportunity set for a two asset combination. Indicate the correct efficient set with labels; explain why it is so.
