You are responsible for managing a portfolio of two investments for the coming year. You have read all of the latest financial news and according to your favourite reputable financial analysts, the probability of another recession occurring is 30% and the probability of a boom is 20%; otherwise the economy will be behaving normally. Common shares of Firm A are expected to earn a return of 30% during boom times, but lose 10% during a recession. Normally, the firms common shares would earn a 20% return. The price of Firm Bs common shares is expected to decline 10% during boom times, but increase by 6% during a recession. Normally the firms common shares would earn a 9% return.

Questions:

G) Compare the return versus risk of a portfolio 100% invested in Firm B's shares with the return versus risk of the portfolio consisting of 30% invested in Firm A and 70% in Firm B. Which would you prefer? Why?

h. Find the Minimum Variance Portfolio (MVP) consisting of some combination of shares of both Firm A and Firm B. What proportion of the portfolio must be invested in Firm A's common shares and what proportion in those of firm B to achieve the MVP? (Use the "Solver" tool in Excel.)

I) Calculate the standard deviation of expected returns on the MVP?

J) Calculate the expected return on the MVP?
