...Synthetic Forward and PutCallParity A synthetic long forward can be created by purchasing a call option and writing a put option with the same strike price and the same expiration date. Let’s say, that an investor buys a $500‐strike call option and sells a $500‐strike put option, both options have the same expiration time T. At T, the spot price will be equal to, above or below the strike price. If the spot price is above the strike price K, the investor will exercise the call option and buy the underlier for $500. The put will not be exercised. If the spot price is below the strike price the written put will be exercised against the investor, forcing him to buy the underlier at $500. The call will expire worthless. In either case, the underlier will be purchased at the strike price. The payoff of this combined position is max{0, S - K}- max{0, K - S} = S - K Call Put but this is actually the payoff of a long forward contract expiring at time T and with a forward price of $500. Be aware of the differences between an original long forward and a synthetic long forward: (i) the original long forward has no upfront premium payment while the synthetic long forward requires a net option premium (= abs[Call(K,T) – Put(K,T)] ) as upfront payment. (ii) At expiration at time T we pay the forward price with the original long forward, whereas with the synthetic long forward we pay the strike price. Let F0,T denote the “no‐arbitrage” forward price. This means you have to pay $0 today and at ...

What is a lower bound for the price of a four-month call option on a non-dividend-paying stock when the stock price is $28, the strike price is $25, and the risk-free interest rate is 8% per annum? The lower bound is [pic] Problem 10.3. What is a lower bound for the price of a one-month European put option on a non-dividend-paying stock when the stock price is $12, the strike price is $15, and the risk-free interest rate is 6% per annum? The lower bound is [pic] Problem 10.4. Give two reasons that the early exercise of an American call option on a non-dividend-paying stock is not optimal. The first reason should involve the time value of money. The second reason should apply even if interest rates are zero. Delaying exercise delays the payment of the strike price. This means that the option holder is able to earn interest on the strike price for a longer period of time. Delaying exercise also provides insurance against the stock price falling below the strike price by the expiration date. Assume that the option holder has an amount of cash [pic] and that interest rates are zero. When the option is exercised early it is worth [pic] at expiration. Delaying exercise means that it will be worth [pic] at expiration. Problem 10.5. “The early exercise of an American put is a trade-off between the time value of money and the insurance value of a put." Explain this statement. An American put when held in conjunction with the underlying stock provides...

...investment strategies: 1. Buying the stock (LONG STOCK): is when we buy a stock of AT&T with a Spot Price(So) of $55 in time zero (t=0) with the expectation that the asset will rise in value. Profit is equal to Stock Price minus the Spot Price. If the Stock Price is greater than the Spot Price we will have a profit, and if the Stock Price is less than the Spot Price we will have a loss. Page 5: 2. Buying a call option (LONG CALL): A call option is a contract in which the buyer has the right ,but not the obligation to buy 100 shares of AT&T at a specified price(Strike Price of $55 within a fixed period of time until its expiration in 4 days, at call premium of (c) $0.5. Profit is equal to Stock Price minus the strike price minus the call premium. In order to use this strategy, the investing firm must be expecting that the Stock Price will increase in the future. By exercising the call option, the company will buy the stock at the strike price and sell it for St in the market. Page 6: 3. Writing a Call option (SHORT CALL): A call option is a...

...in 67 days, we must use 68 days since that is the option's time to expiration. 2. (Minimum Value of a Call) This would create an arbitrage opportunity. The call would be purchased and immediately exercised. For example, suppose S0 = 44, X = 40, and the call price is $3. Then an investor would buy the call and immediately exercise it. This would cost $3 for the call and $40 for the stock. Then the stock would be immediately sold for $44, netting a risk-free profit of $1. In other words, the investor could obtain a $44 stock for $43. Since everyone would do this, it would drive the price of the call up to at least $4. If the call were European, however, immediate exercise would not be possible (unless, of course, it was the expiration day), so the European call could technically sell for less than the intrinsic value of the American call. We saw, though, that the European call has a lower bound of the stock price minus the present value of the exercise price (assuming no dividends). Since this is greater than the intrinsic value, the European call would sell for more than the intrinsic value. Then at expiration, it would sell for the intrinsic value. 3. (Lower Bound of a European Call) The call is underpriced, so buy the call, sell short the stock, and buy risk-free bonds with face value of X. The cash received from the stock is greater than the cost of the call and bonds. Thus, there is a positive cash flow up front. The payoffs from the portfolio at expiration...

...CHAPTER 7: ADVANCED OPTION STRATEGIES END-OF-CHAPTER QUESTIONS AND PROBLEMS 1. (Bull Spread) Buy one put with exercise price X1 and sell one put with exercise price X2. The profit equation is ( = Max(0, X1 – ST) – P1 – Max(0, X2 – ST) + P2 If ST < X1 < X2 ( = X1 – ST – P1 – X2 + ST + P2 = X1 – X2 – (P1 – P2) Recall from Chapter 3 that the difference between exercise prices is less than the difference between premiums. Since X1 < X2 and P1 < P2, the above profit is negative. If X1 < ST < X2 ( = – P1 – X2 + ST + P2 This figure increases dollar for dollar with ST. The breakeven is found by setting the profit to zero, – P1 – X2 + ST* + P2 = 0 and solving for ST* ST* = X2 + (P1 – P2) If X1 < X2 ( ST ( = – P1 + P2 Since P2 > P1, this figure is positive. The minimum profit occurs in the first profit range, ST < X1 < X2 and equals X1 – X2 – (P1 – P2). The maximum profit occurs in the third profit range, X1 < X2 < ST and equals – P1 + P2. 2. (Straddle) A straddle is a strategy based on the expectation that the market will have high volatility. If, however, everyone else in the market believes that the market will have high volatility, then the prices of the call and put will reflect the higher volatility, which will result in breakeven points further away from the current stock price. A straddle is most likely to be successful when the investor believes that the market will be more volatile...
