3. One year ago, a U.S. investor converted dollars to yen and purchased 500 shares of stock in a Japanese company at a price of 4,000 yen per share. The stock's total purchase cost was 700,000 yen. At the time of purchase, in the currency market 1 yen equaled 50.00952. Today, the stock is selling at a price of 3,465 yen per share, and in the currency market $1 equals 120 yen. The stock does not pay a dividend. If the investor were to sell the stock today and convert the proceeds back to dollars, what would be his realized return on his initial dollar investment from holding the stock? Show all your work
