10. Stock XYZ has a current price of 100. The forward price for delivery of this stock in 1 year is 110. Unless otherwise indicated, the stock pays no dividends and the annual effective risk-free interest rate is 10%. Determine which of the following statements is FALSE. (A) The time-1 profit diagram and the time-1 payoff diagram for long positions in this forward contract are identical. (B) The time-1 profit for a long position in this forward contract is exactly opposite to the time-1 profit for the corresponding short forward position. (C) There is no comparative advantage to investing in the stock versus investing in the forward contract. (D) If the 10% interest rate was continuously compounded instead of annual effective, then it would be more beneficial to invest in the stock, rather than the forward contract. (E) If there was a dividend of 3.00 paid 6 months from now, then it would be more beneficial to invest in the stock, rather than the forward contract.

11. Stock XYZ has the following characteristics: The current price is 40. The price of a 35-strike 1-year European call option is 9.12. The price of a 40-strike 1-year European call option is 6.22. The price of a 45-strike 1-year European call option is 4.08. The annual effective risk-free interest rate is 8%. Let S be the price of the stock one year from now. All call positions being compared are long. Determine the range for S such that the 45-strike call produce a higher profit than the 40- strike call, but a lower profit than the 35-strike call. (A) S < 38.13 (B) 38.13 < S < 40.44 (C) 40.44 < S < 42.31 (D) S > 42.31 (E) The range is empty.

12. Consider a European put option on a stock index without dividends, with 6 months to expiration and a strike price of 1,000. Suppose that the effective six-month interest rate is 2%, and that the put costs 74.20 today. Calculate the price that the index must be in 6 months so that being long in the put would produce the same profit as being short in the put. (A) 922.83 (B) 924.32 (C) 1,000.00 (D) 1,075.68 (E) 1,077.17

13. A trader shorts one share of a stock index for 50 and buys a 60-strike European call option on that stock that expires in 2 years for 10. Assume the annual effective risk-free interest rate is 3%. The stock index increases to 75 after 2 years. Calculate the profit on your combined position, and determine an alternative name for this combined position.
