Question The price of a share follows the geometric Brownian motion with parameters u = 0.1 and o=0.2. Presently, the share's price is 33. The continuously compounded interest rate is 5%. (a) A European put option on this share has expiration time T and the strike price K. Using the Black-Scholes formula for the price of a Call(K, T), write down the formula for the price P of this put option. Hint Use the call-put parity formula. (b) Suppose now that the put option has the expiration time T = 1.5 years and the strike price K = 35. A trader who sells this option at time t = 0 for P has to design a hedging strategy which would allow him to meet his financial obligation in 1.5 year's time. The hedging portfolio should consist of underlying shares and of money deposited in the bank. (i) State the formulae allowing one to compute the number of shares in the portfolio and the capital deposited in the bank at any time t, 0
