We will derive a two-state put option value in this problem. Data: S₀ = 270; X = 300; r = 5%. The two possibilities for S_Tare 360 and 160.

a. Find that the range of S is _______ . Find that the range of P is _____ across the two states. What is the hedge ratio Delta of the put?

b. Form a portfolio of -Delta shares of stock and 1 (one) put. What is the (nonrandom) payoff to this portfolio?

c. What is the present value of the portfolio?

d. Given the stock current selling price, calculate the put value.

We will derive a two-state CALL option C value in this problem. Data: S₀ = 270; X = 300; r = 5%. The two possibilities for S_T are 360 and 160.

a. Find that the range of S is _______ . Find that the range of C is _____ across the two states. What is the hedge ratio Delta of the CALL?

b. Form a portfolio of -Delta shares of stock and 1 (one) CALL. What is the (nonrandom) payoff to this portfolio?

c. What is the present value of the portfolio?

d. Given the stock current selling price, calculate the CALL value.

Use your results from previous two problems, check whether call-put parity holds for these options.

(1) Please use binomial option pricing model to derive the value of a one-year put option. The current share price is ?0 = 100 and exercise price ? = 110. The T-bill rate is ? = 10% per year and annual standard deviation is 20%. (2) Use the Black-Scholes formula to find the value of the same option in the previous problem and compare the difference between these two types of methods.

The price of a stock (S0) is $75. A trader sells 6 (N) put option contracts (each contract of 100) on the stock with a strike price (K) of $78 when the option price (c) is $5. The options are exercised when the stock price (S1) is $74. What is the trader’s net profit or loss? Solve in following 4 steps. a) Option profit = K – S0 ___________________________________________________ b) Trader’s gain per option = c – (K – S0)...
