To compute:The Value of a stock-plus-put position as on the ending date of the option.
Introduction:
Put-Call parity relationship: It is a relationship defined among the amounts of European put options and European call options of the given same class. The condition implied here is that the underlying asset, strike price, and expiration dates are the same in both the options. The Put-Call
Parity equation is as follows:
Where C= Call premium
P=Put premium
X=Strike Price of Call and Put
r=Annual interest rate
t= Time in years
S0= Initial price of underlying

To compute: The value of the portfolio as on the ending date of the option when portfolio includes a call option and zero-coupon bond with face value (X+D) and make sure its value equals the stock plus-put portfolio.

- Show how you would make a portfolio delta-neutral and also self-financing by including bonds and call options to a stock that is currently traded at sh. 100, given that the delta for the call = 0.2499 and the call price = sh5.55.arrow_forwardConsider an european call option on a stock that is not paying dividends with the following characteristics. (i) The stock price at t = 0 is S = $30. (ii) The stricke price is $31. (iii) The volatility of the stock is 20%. (iv) The free risk interest rate is 7%.

- Consider a European call option and a European put option that have the same underlying stock, the same strike price K = 40, and the same expiration date 6 months from now. The current stock price is $45. a) Suppose the annualized risk-free rate r = 2%, what is the difference between the call premium and the put premium implied by no-arbitrage? b) Suppose the annualized risk-free borrowing rate = 4%, and the annualized risk-free lending rate = 2%. Find the maximum and minimum difference between the call premium and the put premium, i.e., C − P such that there is no arbitrage opportunities.arrow_forwardConsider the 1-period binomial model with a bond with A(0) = 60 and A(1) = 70 and a stock with S(0) = 4X and S^u(1) 6Y and S^d(1) = 3Z. = 1.

Set up a system of linear equations to determine a replicating portfolio for the call option from part 2 (strike price 45). 5. Solve it and determine the price C(O). 6. Compute, tabulate, and plot the price C(O) as you vary the strike price of the option from 28, 29, ..., 71, 72.arrow_forwardConsider two European call options with strike K and the same underlying non- dividend paying stock. The stock price is currently at So. Option 1 has price C₁ maturity T₁ and Option 2 has price C₂ and maturity T2, where T₂ > T₁. The risk-free interest rate is r. Use a no-arbitrage argument to prove that C₂ > C₁-arrow_forward
- Reconsider the determination of the hedge ratio in the two-state model, where we showed that one-third share of stock would hedge one option. What would be the hedge ratio for the following exercise prices: (a) 120, (b) 110, (c) 100, (d) 90? (e) What do you conclude about the hedge ratio as the option becomes progressively more in the money?arrow_forwardForward prices of the form Fo = S,e"" are sometimes referred to as “risk-adjusted expected future spot prices". If a stock's expected annualized log return is a (i.e. E[Sr] Soear, or – In ("5") = a), show that the expected annualized log return over the period So t = 0 → T (i.e. the rate of appreciation in F) on a forward contract with maturity T years written on that stock must be equal to the risk premium a – r, where r is the annualized risk-free rate. Explain the surprising result that an asset that requires zero initialarrow_forwardUsing the binomial call option model to find the current value of a call option with a $25 exercise price on a stock currently priced at $26. Assume the option expires at the end of two periods, the riskless interest rate is ½ percent per period. What are the hedge ratios?arrow_forward
- You are evaluating a put option based on the following information: P = Ke-H•N(-d,) – S-N(-d,) Stock price, So Exercise price, k = RM 11 = RM 10 = 0.10 Maturity, T= 90 days = 0.25 Standard deviation, o = 0.5 Interest rate, r Calculate the fair value of the put based on Black-Scholes pricing model. Cumulative normal distribution table is provided at the back.arrow_forwardConsider a portfolio consisting of one share and several European call options with the same expiry, but different strike prices. The payoff diagram of the portfolio is given by the following figure. Find the strike prices and the positions of each call option.
