Suppose the call money rate is 6.8 percent, and you pay a spread of 1.9 percent over that. You buy 1,300 shares at $65 per share with an initial margin of 50 percent. One year later, the stock is selling for $70 per share and you close out your position. What is your return assuming no dividends are paid? (Do not round intermediate calculations. Enter your answer as a percent rounded to 2 decimal places.)
