Though it is not a strategy but much of a technique you can as well develop a great strategy from it by making currency demand of currency high so that its value can be increased as well. Using the relative value of currencies between their pairs can give you some insight into where the market might be going. c). minimum profit of strategy = strike price of long call – strike price of lower long call + net premium – commission paid = $100 - $4 - $(3% of 95) = $93.15 2. = 100 + -1(C1) + 1(C2) = 0,- C1 + C2 = -100, 100 = C1 + C2 In relation to the result the constructed call option is a long call. 3. b). , = 90)) = 0 + 14.81 = C1 = -30.19. = = C2 = 4050.06 With the equality of the stock prices and the exchange price is different, therefore the payoff diagram will be bear vertical call spread.

Æ © = SRS, where S is a diagonal matrix for standard deviation. = 0.4896 2. , = = =0.4896  µ - 0.04896 = 0,  µ = = 0.1 b). the most important is the first moment given by: Where,  µn = Rn = = 231.46522E + 0.1EP = 17.4034 , = 231.56522E = The portfolio risk of return is quantified by à °2p in mean-variance analysis, only the first moments are considered in the portfolio model. Investment theory prior to Markowitz considered the maximization of  µp but without à °p The mean portfolio is zero since at time zero the tangency portfolio is absolute zero. 3. X = X = X = 0.2037 F = 0.033 N/B: Notice that variance of the portfolio return depends on three variance terms and six covariance terms. Hence, with four assets there are twice as many covariance terms than variance terms contributing to portfolio variance. Works Cited Day, R. A., and A. L. Underwood. Quantitative analysis. 2d ed.
