Textbook Question
Chapter 11.3, Problem 23P
Suppose you currently have a portfolio of three stocks, A, B, and C. You own 500 shares of A, 300 of B, and 1000 of C. The current share prices are $42.76, $81.33, and, $58.22, respectively. You plan to hold this portfolio for at least a year. During the coming year, economists have predicted that the national economy will be awful, stable, or great with probabilities 0.2, 0.5, and 0.3. Given the state of the economy, the returns (one-year percentage changes) of the three stocks are independent and normally distributed. However, the means and standard deviations of these returns depend on the state of the economy, as indicated in the file P11_23.xlsx.
- a. Use @RISK to simulate the value of the portfolio and the portfolio return in the next year. How likely is it that you will have a negative return? How likely is it that you will have a return of at least 25%?
- b. Suppose you had a crystal ball where you could predict the state of the economy with certainty. The stock returns would still be uncertain, but you would know whether your means and standard deviations come from row 6, 7, or 8 of the P11_23.xlsx file. If you learn, with certainty, that the economy is going to be great in the next year, run the appropriate simulation to answer the same questions as in part a. Repeat this if you learn that the economy is going to be awful. How do these results compare with those in part a?

On Monday, a certain stock closed at $10 per share. Before the stock market opens on Tuesday, you expect the stock to close at $9, $10, or $11 per share, with respective probabilities 0.3, 0.3, and 0.4. Looking ahead to Wednesday, you expect the stock to close 10 percent lower, unchanged, or 10 percent higher than Tuesday’s close, with the following probabilities.
Tuesday's Close

Early on Tuesday, you are directed to buy 100 shares of the stock before Thursday. All purchases are made at the end of the day, at the known closing price for that day, so your only options are to buy at the end of Tuesday or at the end of Wednesday. You wish to determine the optimal strategy for whether to buy on Tuesday or defer the purchase until Wednesday, given the Tuesday closing price, to minimize the expected purchase price.

Scenario
Your corporation has just approved an 8-year expansion plan to grow its market share. The plan requires an influx of cash in each of the 8 years. Management wants to develop a financial plan to ensure the cash needed for the expansion will be available at the beginning of each of the 8 years.
The corporation has the following investment options:
Security
Price per unit
Return Rate (%)
Years to Maturity
1
$1,200
10.255
5
2
$1,000
6.7550
6
3
$1,175
12.110
7
Savings Account
5.500
Each unit of security 1, 2, and 3 guarantees to pay $1,000 at maturity. Investments in these securities must take place only at the beginning of year 1 and will be held until maturity. Any funds not invested in securities will be invested in a savings account that pays the annual interest rates noted above.
The following table summarizes the cash needs for the expansion plan for each of the 8 years:
Year 1 = $250,000
Year 5 = $295,000…
Your company is scheduled to receive 2, 000, 000 euros in 1 year. The euro is currently trading at 1.0813, you can borrow in the US for 1 year at 5.5% or invest in the US at 5.2%. You can borrow in euros at 3.6% or invest in euros at 3.3%. If you use a money market hedge on the receivable, how much will you get in US dollars?

- You are considering three investment alternatives for some spare cash: Old Reliable Corporation stock (A1), Fly-By-Nite Air Cargo Company stock (A2), and a federally insured savings certificate (A3). You expect the economy will either "boom" (N1) or “bust” (N2), and you estimate that a boom is more likely (p1 = 0.6) than a bust (p2 = 0.4).
