Suppose you have just purchased a 10-year General Electric 100 million zero-coupon bond at 8% YTM. The exchange rate is USD1.1/EUR. What will be your rate of return if one year from now the YTM on similar bonds have dropped to 3% and the exchange rate is USD1.2/EUR? (we will always assume we are an American investor). Please enter your answer as a percentage -- e.g. if your answer is 2.456% please type 2.456.
