Consider a three-month American call option on 62,500. For this option to be considered at-the-money, the strike price must be:a) $1.30 = 1.00b) $1.25 = 1.00c) $1.25 (1+i$)3/12 = 1.00 (1+i)3/12d) none of the aboveAnswer: b)30 The current spot exchange rate is $1.25 = 1.00 and the three-month forward rate is $1.30 = 1.00. Consider a three-month American call option on 62,500 with a strike price of $1.20 = 1.00. Immediate exercise of this option will generate a profit ofa) $6,125b) $6,125/(1+i$)3/12 c) negative profit, so exercise would not occurd) $3,125Answer: d)Rationale: with early exercise, you can pay $1.20 for something worth $1.25. So you make a nickel. Make a nickel 62,500 times and youve made $3,125.31 The current spot exchange rate is $1.25 = 1.00 and the three-month forward rate is $1.30 = 1.00. Consider a three-month American call option on 62,500 with a strike price of $1.20 = 1.00.

With a strike price of $1.20 = 1.00 the exchange rate has to go to $1.28 = 1.00 for you to break even.32 Consider the graph of a call option shown at right. The option is a three-month American call option on 62,500 with a strike price of $1.20 = 1.00 and an option premium of $3,125. What are the values of A, B, and C, respectively?a) A = $3,125 (or $.05 depending on your scale); B = $1.20; C = $1.25b) A = 3,750 (or .06 depending on your scale); B = $1.20; C = $1.25c) A = $.05; B = $1.25; C = $1.30d) none of the aboveAnswer: a)33 Which of
