1 Problem ACTS 4302 SOLUTION TO MIDTERM EXAM Derivatives Markets, Chapters 9, 0,, 2, 8. October 2, 200 (Thurs) (i) The current exchange rate is 0.0$/. (ii) A fouryear dollardenominated European put option on yen with a strike price of $0.008 sells for $ (iii) The continuously compounded riskfree interest rate on dollars is 3%. (iv) The continuously compounded riskfree interest rate on yen is.5%. Calculate the price of a fouryear yendenominated European put option on dollars with a strike price of 25. Solution. By the Put Call Parity (PCP) for currency options with x 0 as a spot exchange rate: C(x 0, K, T ) P (x 0, K, T ) = x 0 e r f T Ke r dt C = 0.0 e e = By the CallPut relationship in foreign and domestic currency: P f ( x 0, K, T ) = K x 0 C d (x 0, K, T ) Hence, the price of a fouryear yendenominated European put option on dollars with a strike price of = 25 is P = Problem = (i) C(K, T) denotes the current price of a Kstrike Tyear European call option on a nondividendpaying stock. (ii) P(K, T) denotes the current price of a Kstrike Tyear European put option on the same stock. (iii) S denotes the current price of the stock. (iv) The continuously compounded riskfree interest rate is r. Which of the following is (are) correct? (I) 0 C(50, T ) C(55, T ) 5e rt (II) 50e rt P (45, T ) C(50, T ) + S 55e rt (III) 45e rt P (45, T ) C(50, T ) + S 50e rt Solution. Since the maximum possible value of the difference between the two calls is: using K = 50 and K 2 = 55, we have: Since by direction property : if K K 2 then max(c(k ) C(K 2 )) = e rt (K 2 K ) C(50, T ) C(55, T ) 5e rt C(K ) C(K 2 )
2 2 again using K = 50 and K 2 = 55, we have C(50, T ) C(55, T ) 0 Therefore, I is true. By the Put Call Parity for a nondividend paying stock: C(S, K, T ) P (S, K, T ) = S Ke rt P (S, K, T ) C(S, K, T ) + S = Ke rt For K = 50, the equality becomes: Since by direction property : if K K 2 then using K = 45 and K 2 = 50, we have: P (S, 50, T ) C(S, 50, T ) + S = 50e rt P (K ) P (K 2 ) P (45) P (50) P (S, 45, T ) C(S, 50, T ) + S 50e rt On the other hand, for K = 45, the Put Call Parity becomes: Since by direction property : if K K 2 then using K = 45 and K 2 = 50, we have: Therefore, III is true. Thus, II is not true. P (S, 45, T ) C(S, 45, T ) + S = 45e rt C(K ) C(K 2 ) C(50) C(45) P (S, 45, T ) C(S, 50, T ) + S 45e rt Problem 3 Assume the BlackScholes framework. Eight months ago, an investor borrowed money at the riskfree interest rate to purchase a oneyear 75strike European call option on a nondividendpaying stock. At that time, the price of the call option was 8. Today, the stock price is 85. The investor decides to close out all positions. (i) The continuously compounded riskfree interest rate is 5%. (ii) The stock s volatility is 26%. Calculate the eightmonth holding profit. Solution. 8 months after purchasing the option, the remaining time to expiration is 4 months. We are given: Eur. call, t = 3, S = 85, K = 75, σ = 0.26, r = 0.05, δ = 0. C = Se δt N(d ) Ke rt N(d 2 ), where d = ln (S/K) + (r δ + 2 σ2 )t σ t N(d ) = N(.02) = = ln 85 d 2 = d σ t = = N(d 2 ) = N(0.87) = Ke rt = 75e = Se δt = ( ) C = = = = 0.53 =
3 3 Therefore, the holding profit is: Problem e = = Assume the BlackScholes framework holds. Consider an option on a stock. You are given the following information at time 0: (i) The stock price is S(0), which is greater than 80. (ii) The option price is (iii) The option delta is 0.8 (iv) The option gamma is The stock price changes to Using the deltagamma approximation, you find that the option price changes to 2.2. Determine S(0). Solution. Deltagamma approximation C(S t+h ) = C(S t ) + ɛ + 2 Γɛ2 C(S t+h ) C(S t ) = ɛ + 2 Γɛ2, ɛ = S t+h S t Thus: = 0.8ɛ ɛ ɛ 2 0.8ɛ = 0 D = = = ɛ = = or ɛ 2 = Since S(0) > 80, ɛ = 86 S(0) < = 6. Therefore, ɛ = and S(0) = = = Problem 5 A nondividend paying stock s price is currently 40. It is known that at the end of one month the stock s price will be either 42 or 38. The continuously compounded riskfree rate is Assume that the expected return on the stock is 0% as opposed to the riskfree rate. What is the true discount rate (rate of return) for the onemonth European call option with a strike price of 39? Solution. We are given: T = 2, n =, S = 40, K = 39, S u = 42, S d = 38, α = 0., r = 0.08, δ = 0. We need to find γ. The stock tree: S = 40 us = 42 ds = 38 The call tree:
4 4 C u = 3 C C d = 0 Note that u = Using equation that connects p and p : Since C d = 0, Using formulas for p and p : Therefore, Problem 6 =.05 and d = = 0.95 e γh (pc u + ( p)c d ) = e rh (p C u + ( p )C d ) e γh p = e rh p γ = h ln e rh p p = e(α δ)h d u d p = e(r δ)h d u d = e = e = = e γ = 2 ln = A stock s price follows a lognormal model. (i) The initial price is 90. (ii) α = 0.2. (iii) δ = (iv) σ = 0.3. Construct a 92% confidence interval for the price of the stock at the end of five years. Solution. The lognormal parameters m and v for the distribution of the stock price after five years are m = (α δ 0.5σ 2 )t = ( )5 = = v = σ t = = If Z N(m, v 2 ), then the 00( α)% confidence interval is defined to be ( m zα/2 v, m + z α/2 v ), where z α/2 is the number such that P [ ] α Z > z α/2 = 2 In our case α = 0.08 α 2 = 0.04 and P [Z > z 0.04 ] = 0.04 P [Z < z 0.04 ] = 0.04 P [Z < z 0.04 ] = 0.96 z 0.04 =.75 The confidence interval is ( m zα/2 v, m + z α/2 v ) = ( , ) = (.0989,.2489) p
5 5 Exponentiating, we get ( e.0989, e.2489) = (0.3332, ) Multiplying by the initial stock price of 90, the answer is (29.99, 33.79). Problem 7 For a twoyear 00strike American call option on a stock is modeled with a 2period binomial tree. (i) The initial stock price is 00. (ii) The tree is constructed based on forward prices. (iii) The continuously compounded riskfree interest rate is 5%. (iv) The stock s volatility is 30%. (v) The stock pays dividends at the rate of 5%. Determine the option premium. Solution. We are given: T = 2, n = 2, r = 0.05, γ = 0.05, S = 00, K = 00, σ = 0.3. We need to find C. Since the binomial tree is constructed using forward prices, we have: The stock tree: u = e (r δ)h+σ h = e ( ) +0.3 = e 0.3 =.3499 d = e (r δ)h σ h = e ( ) 0.3 = e 0.3 = us = u 2 S = 82.2 S = 00 uds = 00 ds = d 2 S = The call tree: C uu = 82.2 C u C C ud = 0 C d C dd = 0 Using the formula for risk neutral probability: p = + e σ h = + e 0.3 = , p =
6 6 We now use the formula for pricing an option with risk neutral probability: C u = e rh (p C uu + ( p )C ud ) = e = C d = e rh (p C ud + ( p )C dd ) = 0 Note that if the call is exercised at node u, the payoff will be = This is greater than obtained above, so it is optimal to exercise the call at that point and we ll use C u = in further calculations. C = e rh (p C u + ( p )C d ) = e = 4.64
