Suppose that in the situation of Table 1.1 a corporate treasurer said: "I will have $£ 1$ million to sell in 6 months. If the exchange rate is less than 1.42 , I want you to give me 1.42. If it is greater than 1.48 , I will accept 1.48 . If the exchange rate between 1.42 and 1.48 , I will sell the sterling for the exchange rate." How could you use options to satisfy the treasurer?
