d. The two returns differ due to the change in the exchange rate between the peso and the dollar. The peso had
depreciation (and thus the dollar appreciated) between the purchase date and the sale date, causing a decrease in
total return. The answer in part c is the more important of the two returns for Joe. An investor in foreign securities
will carry exchange-rate risk.
