B) The portfolios were not adequately diversified because the assets were more positively correlated than expected, so all of the assets had negative returns at the same time. C) The portfolios were adequately diversified, but the assets should have been more positively correlated to protect against recession risk. D) The investors should not have diversified their investments to protect against recession risk.

United Plastics Company produces large plastic cups in a variety of colors. United can produce plain plastic cups that are sold in department stores in inexpensive ten cup bundles. Alternatively, United can sell Novelty Cups which are imprinted with slogans and designs. The printed cups cost more to produce, but they sell for a higher price. The appropriate strategy for United depends upon the state of the economy. Plain cups do better during a recession, while Novelty Cups earn higher profits during normal economic conditions. During a recession, United will earn a $100,000 profit selling plain cups and $40,000 with the Novelty line. Under normal economic conditions, United will earn $120,000 with the plain cups and a $200,000 profit with Novelty Cups. United currently does not use economic forecasts and simply assigns equal probabilities to a recession and normal conditions. a. Using the probabilities assumed by United, what is the expected value of each alternative? Which alternative should the firm pursue? (Your recommendation should include separate recommendations for alternative attitudes toward risk.) b. Calculate and interpret the value to the firm of complete information.

Indifference curve A is shown as tangent to the budget line at a point to the left of indifference curve B's tangency to the same line. A) Investors A and B are equally risk averse. B) Investor A is more risk averse than investor B. C) Investor A is less risk averse than investor B. D) It is not possible to say anything about the risk aversion of the two investors, but they will hold the same portfolio. E) It is not possible to say anything about either the risk aversion or the portfolio of the two investors.

The indifference curves of two investors are plotted against a single budget line. Indifference curve A is shown as tangent to the budget line at a point to the left of indifference curve B's tangency to the same line. A) Investors A and B will hold the same portfolio. B) Investors A and B will have different portfolios of the same standard deviation. C) Investors A and B will have different portfolios of the same rate of return. D) Investors A and B will have different portfolios but have the same level of risk aversion. E) Investor A will expect to earn a lower rate of return than investor B.

Jack is near retirement and worried that if the stock market falls he will not be able to wait to take his funds out, and will have to sell at the bottom of the market. Richard thinks the probability of a stock market downturn is the same, but he is only 40 and could therefore wait for another turnaround. They face the same budget line. Jack's risk/return indifference curve: A) will be concave; Richard's will be convex. B) will be convex; Richard's will be concave. C) will be tangent to the budget line at a point to the left of Richard's. D) will be tangent to the budget line at a point to the right of Richard's. E) must still be tangent to the budget line at the same point as Richard's.

Consider the following statements when answering this question; I. The variance of the returns of an investor's portfolio can be reduced by selling assets from the portfolio, and investing the proceeds in other assets where returns are positively correlated with the portfolio's remaining assets. II) The value of complete information is always positive. A) I and II are true. B) I is true and II is false. C) I is false and II is true. D) I and II are false.

Consider the following statements when answering this question: I. The allocation of a risk-averse investor's portfolio between a risk free asset and a risky asset never changes if the rate of return on both assets increases by the same amount. II) Given the choice between investing in a risk free asset or a risky asset with higher expected returns, the utility maximizing portfolio of a risk neutral or risk loving investor would never include the risk free asset. A) I and II are true. B) I is true and II is false. C) I is false and II is true. D) I and II are false.

Is it possible for an investor to allocate more than 100% of their assets to the stock market? A) No, this is not theoretically plausible. B) No, federal law prohibits this kind of investment. C) Yes, investors can borrow money to buy stocks on margin. D) none of the above

Suppose an investor equally allocates their wealth between a risk-free asset and a risky asset. If the MRS of the current allocation is less than the slope of the budget line, then the investor should: A) shift more of their wealth to the risky asset. B) shift more of their wealth to the risk-free asset. C) keep the same asset allocation. D) We do not have enough information to answer this question.

Use the following statements to answer this question: I. The real rate of return on an investment is the nominal return minus the rate of inflation. II) The real rate of return on an investment cannot be negative. A) I and II are true. B) I is true and II is false. C) II is true and I is false. D) I and II are false.

The risk-return indifference curves for a risk-neutral investor are: A) vertical lines. B) straight lines with slope equal to one. C) horizontal lines. D) upward sloping lines that are bowed downward.

Joan Summers has $100,000 to invest and is considering two alternatives. She can buy a risk free asset that will pay 10% or she can invest in a stock that has a 0.4 chance of paying 15%, a 0.3 chance of paying 18%, and a 0.3 chance of providing a 6% return. Joan plans to invest $70,000 in the stock and $30,000 in the risk free asset. a. Determine the expected percentage return on the stock and the standard deviation. b. Calculate the weighted average return on the portfolio, given the planned investment strategy outlined above. c. Determine the standard deviation for the portfolio. d. Write the equation that represents the budget line in the risk-return tradeoff. What is the slope of the budget line? Interpret this slope.

Mel and Christy are co-workers with different risk attitudes. Both have investments in the stock market and hold U.S. Treasury securities (which provide the risk free rate of return). Mel's marginal rate of substitution of return for risk where is the individual's portfolio rate of return and σP is the individual's portfolio risk. Christy's Each co-worker's budget constraint is where is the risk-free rate of return, is the stock market rate of return, and is the stock market risk. Solve for each co-worker's optimal portfolio rate of return as a function of , and .

Donna is considering the option of becoming a co-owner in a business. Her investment choices are to hold a risk free asset that has a return of and co-ownership of the business, which has a rate of return of and a level of risk of . Donna's marginal rate of substitution of return for risk where is Donna's portfolio rate of return and σ_P is her optimal portfolio risk. Donna's budget constraint is given by Solve for Donna's optimal portfolio rate of return and risk as a function of , and . Suppose the table below lists the relevant rates of returns and risks. Use this table to determine Donna's optimal rate or return and risk. Investment Rate of Return Risk Risk Free 0.06 0 Business 0.25 0.39
