A stock investor wants to hedge the Dell stock in his portfolio. How can he use a covered call to do this? Ans The investor owns the stock and will profit if it increases in value or lose if it : decreases. He can write a call and receive the premium from it. The premium will partially offset the loss if the stock price declines. If the stock price increases, he may be called upon to sell it at the exercise price. This would limit his potential gains.

54. A stock investor wants to hedge the Microsoft stock in his portfolio. How can he use a protective put to do this? Ans: The investor owns the stock and will profit if it goes up and lose if it goes down. He buys a put. If the stock increases in value, he gains on the stock and loses the premium he paid for the put. If the stock goes down, he can exercise the put and sell the stock at the exercise price. 55. How can the owner of a large stock portfolio use options on individual stocks to enhance the income from the portfolio? Ans: The owner of a portfolio may enhance the portfolio's income by writing calls and puts for the premium received. If the purchaser exercises the option, however, the writer will have to deliver the stock and may have to take capital losses. 56. What is a hedge ratio? Ans: The hedge ratio for a call is N(d1) from the Black-Scholes model. It is commonly called delta. It shows the change in the price of the option for a $1 change in the price of the underlying stock. The hedge ratio for a put is N(d1) – 1. This knowledge helps the portfolio manager determine how many options contracts are needed to protect the portfolio from price fluctuations. 57. What is the put-call parity? How is it related to arbitrage? Ans: This principle expresses the relationship between the prices of puts and calls on the same stock that must hold if arbitrage is to be ruled out. In other words, unless the price of the put and call have a certain relationship to each other, there will be opportunities for earnings riskless profits (arbitrage). 58. What makes the risk-expected return profile attractive to speculators who purchase put and call options? What is the risk-expected return profile for writers of naked put and call options? Ans: Put and call options offer leverage compared to purchasing the common stock. The upside for puts and calls is unlimited because the potential increase (decrease) in the stock price is unlimited. The downside on options is limited to a 100 percent loss because no margin is allowed. The loss on highly levered futures contracts can be far more. Thus, the advantage of options to speculators is the unlimited upside and the limited downside. In addition, speculators can enter this market with very small amounts of cash compared to the investment required for the stocks themselves. The writer of naked options faces unlimited loss because the stock price can move up without limit or down to zero. The upside gain is limited to the amount received for the option.

59. What are the variables in the Black-Scholes option pricing model? How is each related to the price of the call option? Ans: Price of underlying stock. The higher the stock price, the higher the option price. Exercise price. The higher the exercise price, the lower the option price. Time remaining to expiration. The longer the time, the higher the option price. Interest rate. The higher the interest rate, higher the option price. Volatility of underlying stock. The higher the volatility, the higher the option price. 60. AB Flex Inc. stock is currently trading at $38. The time left until expiration of a call and put trading on AB Flex Inc.'s stock is 6 months and the strike price is $45. If the call is currently trading at $1.96 and the Treasury bill rate is 10 percent per year, what price should the put sell for? Ans: Use put-call parity. Price of put = EP/(ert) – CMP + CP

= 45/(e0.1*0.5) – 38 + 1.96

= 45/1.051271 – 38 + 1.96

= 6.77

62. An investor has the alternative of buying 100 shares of XYZ at $50 per share or investing the same amount of money in XYZ 6-month calls priced at $5. Calculate the profit or loss from each strategy if the price of XYZ rises to $60 within a week. Ans: Buying the stock gain = $10 per share x 100 shares = $1000 Buying 10 option contracts ($5000 to invest/$500 per option contract): gain = 10 options contracts x assumed $10 gain on options = 10 x 1000 per contract = $10,000

Listed below are the option quotes on JUP, Inc., in January of this year. -------Calls--------------Puts-------Options/Strike March June March June JUP 35 3 1/2 4 1/2 1 1/8 37 40 1 1/2 2 4 1/2 5 37 45 1 1 1/2 8 3/8 s 37 50 1/2 r r s (a) Which calls are in the money?

Page 19

Ans: (a) In-the-money calls are those whose EPSP. Hence the March 40, March 45 and June 40 puts are in-the-money. (c) The investors are willing to pay 3 1/2 for the March 35 call option because it has an intrinsic value of 2 and the rest is speculative premium. Investors are probably expecting the stock to go up by March. On the other hand, the March 35 put is outof-the money i.e. it's intrinsic value is zero. There is still some chance that the price may drop below 35, at which time the investor may make a profit. Hence there is a small speculative premium of 1/2 on the put option. (d) Intrinsic Value of June 35 Call = Stock Price - Exercise Price = 37 - 35 = $2 (e) The Intrinsic Value of the March 40 put = Exercise Price - Stock Price = 40 - 37 = $3

65. Use the Black-Scholes model to calculate the theoretical value of a DBA December 45 call option. Assume that the risk free rate of return is 6 percent, the stock has a variance of 36 percent, there are 91 days until expiration of the contract, and DBA stock is currently selling at $50 in the market.

Page 21

Ans: N(d1 )= 0.70 88 (fro m stan dard nor mal table ) N(d2 )= 0.59 87 (fro m stan dard nor mal table ) Valu e of the call = [$10 0(.7 088) ][$90 /e(0.06 )(0.25)] [.59 87]

Value of Call = CMP[N(d1)] – [EP/ert][N(d2)] Where CMP = Current market price = $100 EP = Strike price = $90 r = risk-free rate = 0.06 t = time till maturity in years = 91/365 = 0.25 N(d1) = cumulative density function of d1

d1 =

ln(CMP/EP) + (r + 0.5σ 2 )t σt1/2

2 = variance of the stock's annual rate of return = 0.36 N(d2) = cumulative density function of d2 d2 = d1 - t1/2

= ln(100/90) + [0.06 + 0.5(.36)](0.25) = [0.10536 + 0.06] / 0.3 = 0.5512 70.8 d1 = 1/2 1/ 2 (0.36) (0.25) 8 -

66. You buy 1,000 shares of Sunbeam at 11 1/8 and write 10 calls at a premium of 4 3/8 with a strike price of 7 1/2. The stock goes to 20 in 6 months. You receive a 8 cent dividend per share. If the calls are exercised (which is the likely assumption), what is your percentage return? Ans: Loss on selling stock = sell stock at 7.5 x 1,000 = $7,500

bought stock at 11.125 x 1,000 = 11,125

(3,625)

Dividends received = .08 x 1,000 = $80 Premium received on writing calls = 4.375 x 100 x 10 = $4,375 Total return = $830 Percentage return = $830/11,125 = 7.5%
