Using options to build hedge portfolio. Consider a call option on the British pound (BP) which represents the right to purchase 1,000 at the strike price of $1.30 per . The option will expire in one year. The current spot rate is $1.32 per . In the future, the spot rate may become $1.40 or $1.50 per . The annual risk-free interest rate is 6.0% in the US and 5% in the UK. A pure-discount British bond, that will pay 1,000 on the maturity date, is selling for 952.38 now. (a) If you buy a British bond, how many calls do you have to buy or sell to construct a risk- free hedge portfolio? What is the future dollar value of the hedge portfolio? (b) What is the fair price of this call option? (c) Suppose the call is trading for $20 per contract. Show how you can realize arbitrage profit and determine the profit. Assume you buy or sell one unit of British bond.
