A Peruvian investor buys 150 shares of a U.S. stock for $7,500 ($50 per share). Over the course of a year, the stock goes up by $4 per share.

a. If there is a 10 percent gain in the value of the dollar versus the nuevo sol, what will be the total percentage return to the Peruvian investor? First, determine the new dollar value of the investment and multiply this figure by 1.10. Divide this answer by $7,500 and get a percentage value, and then subtract 100 percent to get the percentage return.

b. Instead assume that the stock increases by $7, but that the dollar decreases by 10 percent versus the nuevo sol. What will be the total percentage return to the Peruvian investor? Use 0.90 in place of 1.10 in this case.
