Design and solve a problem involving EITHER investing on margin OR use of options OR making an investment involving more than one currency (that is, converting from domestic currency to a foreign currency, making a foreign investment, and converting back to the investor’s domestic currency). You should write the problem and solution as if it were going to be published in a textbook on investing. Your answer should go beyond being just the math problem by including a narrative adequate to explain to the reader the possible effects of trading on margin, using options, or making an investment involving a foreign currency.
