You have $5,000 to invest for the next year and are considering three alternatives: A money market fund with an average maturity of 30 days offering a current yield of 2.0% per year A 1-year savings deposit at a bank offering an interest rate of 4.0% A 20-year U.S. Treasury bond offering a yield to maturity of 4.0% per year A 20-year corporate bond offering a yield to maturity of 7. What is the risk profile of each of these assets? What role does your forecast of future interest rates play in your decisions?
