- A stock has a current price of $67. An option on this stock that expires in six months has an exercise price of $65. The stock will pay a dividend of $5 in three months. Assume an annualized volatility of 30% and a continuously compounded risk - free rate of 5% per annum. Use the Black - Sholes - Merton model to price this option. 1) Suppose the option is a European put. Calculate the value of the put. 2) Suppose this option is an American call. Use Black's approximation to calculate the value of this call.The current price of a non-dividend paying stock is $50. Use a two-step tree to value a European put option on the stock with a strike price of $50 that expires in 12 months. Each step is 6 months, the risk free rate is 5% per annum, and the volatility is 50%. What is the value of the option according to the two-step binomial model. Please enter your answer rounded to two decimal places (and no dollar sign).Consider a two-period binomial tree model with u = 1.1 and d = 0.90. Suppose the current price of the stock is $50 and the nominal interest rate is 2%. What is the value of an American put with a strike price of $60 that will expire in 3 months? Use at least four decimal places for those questions that require a numerical answer.
- You want to price an American Put option that is written on the stock of Shelby Ltd. The price of the stock is £20, the risk-free interest rate is 5%, the annualised volatility of the stock is 42% and the option expires in 5 months. Given that information, calculate the up-multiplier to be used in a nine-step binomial tree. Write your answer in decimal form with up to three decimal points Answer:Consider an American Put option with time to expiry of 5 months and a strike price of 82. The current price of the underlying stock is 80. Divide the time to expiry into five 1-month intervals. In each interval, the stock price can either rise by 6, or fall by 6, with unknown probability. The risk-free rate is 4.2% per annum, continuously compounded. Use Binomial Model. (a) What is the evolution of the prices of the underlying asset in time? Show it on a binomial tree.Consider a stock with a current price of P = $27.Suppose that over the next 6 months the stockprice will either go up by a factor of 1.41 or downby a factor of 0.71. Consider a call option on thestock with a strike price of $25 that expires in6 months. The risk-free rate is 6%.(1) Using the binomial model, what are the endingvalues of the stock price? What are the payoffsof the call option?
- Suppose the current value of a popular stock index is 653.50 and the dividend yield on the index is 2.8%. Also, the yield curve is flat at a continuously compounded rate of 5.5%. A.If you estimate the volatility factor for the index to be 16%, use the Black-Scholes model to calculate the value of an index call option with an exercise price of 670 and an expiration date in exactly three months. You may use Appendix D to answer the question. Do not round intermediate calculations. Round your answer to the nearest cent. $ B.If the actual market price of this option is $17.40, calculate the implied volatility coefficient. Do not round intermediate calculations. Round your answer to two decimal places. %Consider a stock, the current price (S.) of which is $30. We model stock-price evolution using a Binomial model. In every three-month period, u = 1.1052 and d = 0.9048. The risk free rate of interest is 5% per annum continuously compounded. The four-step Binomial tree is shown below: 44.75 40.50 36.64 36.64 33.16 33.16 30 30.00 30.00 27.15 27.15 24.56 24.56 22.22 20.11 Node Time: 0.0000 0.2500 0.5000 0.7500 1.0000 A European-style exotic derivative has been written on this stock. The derivative has one year to expiry. Denote by S;, S2, S; and S4 the stock price after three, six, nine and twelve months respectively. The payoff to the derivative is specified as follows: [max(S2,S,)–min(S,,S,) if S, 2 30 Рayoff 3D max(S,S,S,)-S, if S, < 30 Required: Using a four-step Binomial framework and the risk-neutral approach, calculate the current value of this exotic derivative. Use continuous compounding for all present value calculations. Show all working.Suppose a stock, not paying any dividend, is currently trading at $50. The annual volatility of its price is 31.55%. This implies that in a one-period binomial tree model the stock price will either be $62.5 or $40 in six months. The annual interest rate is 5%. Consider a European call option with a strike price of $50 and maturity in six months. In the one-period binomial tree model, what's the fair value of the call?
