Briefly explain the difference between expected returns and realizedreturns and between ex ante returns an ex post returns.Answer: Expected returns are mean returns based on probability distributionsdealing with the future. Realized returns are the returns that actuallyoccurred in the past. Ex ante returns are in the future. Ex post returns arein the past.

Are T-bills totally risk-free? Explain.Answer: No. T-bills are assumed free of default risk since the U.S. governmenthas always paid its debts. But T-bills are still subject to interest rate and inflation risk since their prices may fluctuate if interest rates or inflationchanges.

Considering the Efficient Market Hypothesis, how does new economicinformation affect securities’ prices?Answer: The price adjusts quickly as new economic information is received andis assessed by the market.

1. What are two other names for systematic risk? For unsystematic risk?Answer: Systematic risk is also called market risk and nondiversifiable risk.Unsystematic is also called specific risk and diversifiable risk.

8. Why do U. S. Treasury bills have a standard deviation in Table 6-5 if theyare considered to be risk-free?Answer: Treasury bills are considered to be free of default risk. There is alittle interest rate risk if they are sold before maturity. Over the 70-yeartime period in the table the returns varied from year-to-year, even if heldto maturity. Thus, there is a standard deviation of returns over the period.

1. Are the expected returns and standard deviation of a portfolio bothweighted averages of the individual securities expected returns andstandard deviations? If not, what other factors are required?Answer: The expected return is a weighted average. The portfolio standarddeviation is not a weighted average but also requires correlationcoefficients among the securities.

4. Give an example of two industries that might exhibit low correlation ofreturns. Give an example that might exhibit high correlation.Answer: Low correlation might be found between large appliances andretail food markets in that retail food is somewhat steady througheconomic ups and downs, while appliances tend to fall off duringeconomic slow downs. High correlation might be found between automanufacturers and steel manufacturers.

8. What does a security’s beta measure in the market model? How isthe portfolio’s beta related to the individual securities’ betas?Answer: A security’s beta measures its risk relative to the market. Themarket’s beta is defined as 1.00. Higher betas indicate more risk; lowerbetas indicate less risk than the market. The portfolio beta is the weightedaverage of the securities’ betas.

1. The expected return for the market is 12 percent, with a standard deviationof 20 percent. The expected risk-free rate is 8 percent.
