1. Portfolio Expected return: you have $10000 to invest in a stock portfolio. Your choices are stock x with an expected return of 14 percent and stock y with an expected return of 10.5 percent. If your goal is to create a portfolio with an expected return of 12.4 percent how much money will you invest in stock x? in stock y?

2. Calculating expected return: based on the following information calculate the expected return: based on the following information, calculate the expected return:
State of economy    Probability of state of economy    Portfolio return if state occurs
Recession                                     .25                                              -.08
Boom                                           .75                                                 .21

Returns and variances: consider the following information:
Rate of return if state occurs
State of economy    Probability of state of economy Stock A Stock B Stock C
Boom                                     .35                                           .07          .15       .33
Bust                                        .65                                           .13          .03       -.06

a. What is the expected return on an equally weighted portfolio of these three stocks?
b. What is the variance of a portfolio invested 20 percent each in A and B and 60 percent in C?
3. Economies of scale: what does it mean to say that a proposed merger will take advantage of available economies of scale? Suppose Eastern Power Co. and Western Power Co. are located in different time zones. Both of them operate at 60 percent of capacity except for peak periods, when they operate at 100 percent of capacity. The peak periods begin at 9:00 am and 5:00 pm local time and last about 45 minutes. Explain why a merger between Eastern and Western might make sense.
