Problem 1: A call option of strike K > 0 is a financial contract that payoffs...
Problem 1. [12 pts. Assume that you have purchased a call option with a strike price of S66.0. The option will expire in exactly 6 months' time. When you originally bought the option, you paid S5.0. (Show vour calculations) a. b. Draw a payoff diagram showing the payoff at expiration as a function of the stock price at If the stock is trading at $56 in six months, what will your payoff be? What will your profit be? If the...

Let S(0) = $100.00, K = $92.00, K2 Black-Scholes continuous-time model. $125.00, and r = 5%. Find the Black-Scholes formula for the option paying $10.00 in 3 months if S(T) S Ki or if S(T) 2 K2, and zero otherwise, in the 7. Let S(0) = $100.00, K...
The Black-Scholes-Merton model for stock pricing in discrete time Let So be the initial stock price at time t = 0. At time t = 1,2,-. ., the stock price is S,ett+σ Σ. 2. the drift where a 0 is known as the volatility and the independently and identically distributed standard Normal N(0,1) random 0 is known as Zi variables are (a) Show that S, = S¢_1e#+oZ¢ _ St St-1 (b) What is the distribution of ln (c) What is...

Use Black-Scholes formula to find the price of 1-year call option with strike price of X=$110 if the current stock price is S=100, the standard deviation of annual stock return is 16.9014%, and risk-free interest rate is 7%. You may want to use Excel to do you calculations. Note that Excel function NORM.S.DIST(x,TRUE) is the cumulative distribution function of x for standard Normal (i.e., with mean 0 and standard deviation of 1) distribution.
3. (10 pts) For each k e [0, 1,2,..., 301 the symbol S(k) denotes the price of the stock at time k. A European call option with strike 90 and expiration n- 30 costs 15. A European put option with strike 100 and expiration 30 costs 11. Both options have the same stock as their underlying security. What is the price of the security whose payoff structure is 7S (30) 630, if S(30) 100, S(30)-30, if 90 S(30) S 100,...
1 In this problem c(K,T) denotes the price of a European call option with strike price K and strike time T, p(K,T) is the price of the identical put option, r is the risk-free rate and So is the current price of the underlying security. Which of the following are correct? i 0 <c(50,T) - c(55,T) <5e-rT ii 50e-rT <p(45, T) - c(50,T) + So < 55e-rT iii 45e-T <p(45, T) - c(50,T) + So < 50e-rT
The random variable X has density function F(x)= (k+1)x^2 for 0<x<1 and 0 otherwise, where k is a constant. What is the median of X?
