Exam 8: Risk and Rates of Return

If you plotted the returns of a company against those of the market and found that the slope of your line was negative,the CAPM would indicate that the required rate of return on the stock should be less than the risk-free rate for a well-diversified investor,assuming that the observed relationship is expected to continue in the future.

Since the market return represents the expected return on an average stock,the market return reflects a certain amount of risk.As a result,there exists a market risk premium,which is the amount over and above the risk-free rate that is required to compensate stock investors for assuming an average amount of risk.

Which of the following statements is CORRECT?

The realized return on a stock portfolio is the weighted average of the expected returns on the stocks in the portfolio.

Assume that the risk-free rate,r_RF,increases but the market risk premium,(r_M − r_RF),declines with the net effect being that the overall required return on the market,r_M,remains constant.Which of the following statements is CORRECT?

Stocks A,B,and C all have an expected return of 10% and a standard deviation of 25%.Stocks A and B have returns that are independent of one another,i.e.,their correlation coefficient,r,equals zero.Stocks A and C have returns that are negatively correlated with one another,i.e.,r is less than 0.Portfolio AB is a portfolio with half of its money invested in Stock A and half in Stock B.Portfolio AC is a portfolio with half of its money invested in Stock A and half invested in Stock C.Which of the following statements is CORRECT?

Bad managerial judgments or unforeseen negative events that happen to a firm are defined as "company-specific," or "unsystematic," events,and their effects on investment risk can in theory be diversified away.

Mulherin's stock has a beta of 1.23,its required return is 11.75%,and the risk-free rate is 4.30%.What is the required rate of return on the market? (Hint: First find the market risk premium.)

Consider the following information for three stocks,A,B,and C.The stocks' returns are positively but not perfectly positively correlated with one another,i.e.,the correlations are all between 0 and 1. ​ Portfolio AB has half of its funds invested in Stock A and half in Stock B.Portfolio ABC has one third of its funds invested in each of the three stocks.The risk-free rate is 5%,and the market is in equilibrium,so required returns equal expected returns.Which of the following statements is CORRECT?

Nagel Equipment has a beta of 0.88 and an expected dividend growth rate of 4.00% per year.The T-bill rate is 4.00%,and the T-bond rate is 5.25%.The annual return on the stock market during the past 4 years was 10.25%.Investors expect the average annual future return on the market to be 12.50%.Using the SML,what is the firm's required rate of return?

Assume that the risk-free rate is 5%.Which of the following statements is CORRECT?

A stock's beta is more relevant as a measure of risk to an investor who holds only one stock than to an investor who holds a well-diversified portfolio.

A stock with a beta equal to −1.0 has zero systematic (or market)risk.

Which of the following statements is CORRECT?

Which of the following is NOT a potential problem when estimating and using betas,i.e.,which statement is FALSE?

Bob has a $50,000 stock portfolio with a beta of 1.2,an expected return of 10.8%,and a standard deviation of 25%.Becky also has a $50,000 portfolio,but it has a beta of 0.8,an expected return of 9.2%,and a standard deviation that is also 25%.The correlation coefficient,r,between Bob's and Becky's portfolios is zero.If Bob and Becky marry and combine their portfolios,which of the following best describes their combined $100,000 portfolio?

Diversification will normally reduce the riskiness of a portfolio of stocks.

Over the past 88 years,we have observed that investments with the highest average annual returns also tend to have the highest standard deviations of annual returns.This observation supports the notion that there is a positive correlation between risk and return.Which of the following answers correctly ranks investments from highest to lowest risk (and return),where the security with the highest risk is shown first,the one with the lowest risk last?

Which of the following statements is CORRECT?

Stock A has a beta of 1.2 and a standard deviation of 20%.Stock B has a beta of 0.8 and a standard deviation of 25%.Portfolio P has $200,000 consisting of $100,000 invested in Stock A and $100,000 in Stock B.Which of the following statements is CORRECT? (Assume that the stocks are in equilibrium.)
