Research Project. Suppose your team works for a firm that has $10 million in excess cash to invest for one month. Your team’s task is to invest this money in the foreign exchange market to earn a profit—holding dollars is not an option. Select the currencies you wish to buy at today’s spot rate, but do not buy less than $2.5 million of any single currency. Track the spot rate for each of your currencies over the next month in the business press. On the last day of the month, exchange your currencies at the day’s spot rate. Calculate your team’s gain or loss over the one-month period.
