Questions 1~6

Use this information for the first five (5) questions. An American Hedge Fund is considering a one-year investment in an Italian government bond with a one-year maturity and a euro-denominated rate of return of i = 5%. The bond costs 1,000 today and will return 1,050 at the end of one year without risk. The current exchange rate is 1.00 = $1.50. U.S. dollar-denominated government bonds currently have a yield to maturity of 4%. Suppose that the European Central Bank is considering either tightening or loosening its monetary policy. It is widely believed that in one year there are only two possibilities: S1($|) = $1.80 per or S1($|) = $1.40 per Following revaluation, the exchange rate is expected to remain steady for at least another year 1 Find the NPV in dollars for the American firm if they wait one year to buy the bond after the exchange rate rises to S1($|) = $1.80 per . Assume that i doesn't change. (5 points) 2 Find the NPV in dollors for the American firm if they wait one year to undertake the project after the exchange rate falls to S1($|) = $1.40 per . Assume that i doesn't change. (5 points) 3 The hedge fund manager notices the \"win big\"/\"lose big\" payoffs associated with starting this project today. He asks you to value this bond using risk neutral valuation. (5 points) 1 4 Your banker quotes the euro-zone risk-free rate at i = 5% and the U.S. risk free rate at i$ = 4%. Find the value of the option to delay and thereby the correct value of the bond to a U.S. investor. (5 points) 5 Using your results to the last question, make a recommendation vis--vis when to buy the bond. (5 points) EXTRA CREDIT 6 Using the notion of hedging, make a recommendation vis--vis how to undertake the project today without \"buying\" the option. (5 points) 2
