Security ai ßi sie
1 0.04 1.10 0.10

3 -0.01 1.20 0.32
4 0.02 0.80 0.25

Your tasks are:
1a) Generate active portfolio A (report weights wA1, wA2, wA3, and wA4)
1b) Generate key parameters of portfolio A (report aA , ßA, s2eA; RA, s2A, cov(RA, RM))
1c) Use the information regarding M, rf, and A to produce the parameters of the improved portfolio P (report wM*, wA*, E(rP), and sP)
1d) Produce a simple graph that outlines the locations of M, A, and P in the E(r)-s plane.

2) (20 points) Solve 20.27 from BKM (p. 703).
3) (20 points; 10 points for each problem) Solve 21.11 and 21.12 from BKM (p. 747).
4) (20 points; 10 points for each part) You are holding a $5 million portfolio with a beta of 0.80.
4a) The S&P500 futures beta is 1 and the current level of the index is 1,000. The futures contract is valued at $250 times the index value at the expiration of the contract. Assuming you can hedge with fractional shares of the index, what futures position would you take to hedge yourself as completely as possible?
4b) Suppose you think the market is going to dive, and you want to have the same size portfolio but with a beta of –0.2. What futures position would you take to change your overall market exposure to a beta of –0.2, rather than hedging yourself? You can use fractional shares of the futures.
5) (20 points) You are an importer with a contract to buy 40,000,000 bars of famous Utopian TastesGreat chocolate for a fixed price of 20 Utopian Liras (UTL) each. The current futures price is $0.16/UTL, and the contract specifies delivery of 62,500 UTLs per contact. Assume you can take fractional futures positions if you need to. The exchange rate when you buy the goods will be either $0.18 (with probability 2/3) or $0.15 (with probability 1/3). What position would you take to hedge yourself? Long or short, and how many contracts? Show your resulting total costs (including the futures position) when the exchange rate is $0.18 and when it is $0.15.
