A French investor earned a 12% return, in terms of Euros, on an investment in dollar assets in the U.S. If the return on the investment in dollars was 6%, then the change in the exchange rate: A)
| must have been greater than 6%. |
| B)
| must have been equal to 6%. |
| C)
| must have been less than 6%. |
|
The equation for total return in euros = ($ return) + (change in exchange rate) + ($ return)(change in exchange rate).
Thus,
0.12 = 0.06 + (change in exchange rate) + (0.06)(change in exchange rate),
0.12 - 0.06 = (change in exchange rate) + (0.06)(change in exchange rate)
0.06 = (1.06)(change in exchange rate)
0.06/1.06 = change in exchange rate = 0.0566 or 5.66% < 6%. |
