If the forward price is given to be $1.41/£, identify whether there are any arbitrage opportunities and how you would take advantage of them

11. Three months ago, an investor entered into a six-month forward contract to sell a stock. The delivery price agreed to was $55. Today, the stock is trading at $45.

Assume interest rates are constant at 6% for all maturities. You enter into a long position to buy 10,000 shares of stock in three months’ time. (a) What is the arbitrage-free price of the three-month forward contract? (b) After one month, the stock is trading at $23.50. What is the marked-to-market value of your contract? (c) Now suppose that at this point, the company unexpectedly announces that dividends will be $1.00 per share due to larger-than-expected earnings. Buoyed by the good news, the share price jumps up to $24.50. What is now the marked-to-market value of your position?

Assume the interest rates for these horizons are, respectively, r1, r2, . . . , rN in continuouslycompounded annualized terms. What is the arbitrage-free value of F given a spot price of S?

16. In the absence of interest-rate uncertainty and delivery options, futures and forward prices must be the same. Does this mean the two contracts have identical cash-flow implications? (Hint: Suppose you expected a steady increase in prices. Would you prefer a futures contract with its daily mark-to-market or a forward with its single mark-tomarket at maturity of the contract? What if you expected a steady decrease in prices?)

17. Consider a forward contract on a non-dividend-paying stock. If the term-structure of interest rates is flat (that is, interest rates for all maturities are the same), then the arbitrage-free forward price is obviously increasing in the maturity of the forward contract (i.e., a longer-dated forward contract will have a higher forward price than a shorterdated one). Is this statement true even if the term-structure is not flat?

18. The spot price of copper is $1.47 per lb, and the forward price for delivery in three months is $1.51 per lb. Suppose you can borrow and lend for three months at an interest rate of 6% (in annualized and continuously-compounded terms)

(a) First, suppose there are no holding costs (i.e., no storage costs, no holding benefits). Is there an arbitrage opportunity for you given these prices? If so, provide details of the cash flows. If not, explain why not. (b) Suppose now that the cost of storing copper for three months is $0.03 per lb, payable in advance. How would your answer to Part (a) change? (Note that storage costs are asymmetric: you have to pay storage costs if you are long copper, but you do not receive the storage costs if you short copper.)

19. The SPX index is currently trading at a value of $1,265, and the FESX index (the Dow Jones EuroSTOXX Index of 50 stocks, referred to from here on as “STOXX”) is trading at e3,671.

3. Suppose an active lease market exists for a commodity with a lease rate ` expressed in annualized continuously-compounded terms. Short-sellers can borrow the asset at this rate and investors who are long the asset can lend it out at this rate. Assume the commodity has no other cost of carry.

(b) You estimate the dividend yield to be 1% over the next three months. Is there an arbitrage opportunity from your perspective?

18. The spot US dollar-euro exchange rate is $1.10/euro. The one-year forward exchange rate is $1.0782/euro. If the one-year dollar interest rate is 3%, then what must be the one-year rate on the euro?

One COMEX silver futures contract is for 5,000 oz. You run a regression of daily silver spot price changes on silver futures price changes and find that δs = 0.03 + 0.89δF + What should be the size (number of contracts) of your optimal futures position.

19. A firm plans to borrow money over the next two half-year periods, and is able to obtain a fixed-rate loan at 6% per annum. It can also borrow money at the floating rate of Libor + 0.5%. Libor is currently at 4%. If the 6 × 12 FRA is at a rate of 6%, find the cheapest financing cost for the firm.

20. You enter into an FRA of notional 6 million to borrow on the three-month underlying Libor rate six months from now and lock in the rate of 6%. At the end of six months, if the underlying three-month rate is 6.6% over an actual period of 91 days, what is your payoff given that the payment is made right away? Recall that the Actual/360 convention applies.

23. You anticipate a need to borrow USD 10 million in six-months’ time for a period of three months. You decide to hedge the risk of interest-rate changes using eurodollar futures contracts. Describe the hedging strategy you would follow. What if you decided to use an FRA instead?

Assume that the three-month period has 90 days in it. Using the same numbers from Question 23 and adjusting for tailing the hedge, how many futures contracts are needed? Assume fractional contracts are permitted

25. Using the same numbers as in the previous two questions, compute the payoff after six months (i.e., at maturity) under (a) an FRA and (b) a tailed eurodollar futures contract if the Libor rate at maturity is 5%, and the locked-in rate in both cases is 4%. Also compute the payoffs if the Libor rate ends up at 3%. Comment on the difference in payoffs of the FRA versus the eurodollar futures.
