A 1-year forward price on a stock is $100. The price of a 6-month European call option with strike price of $98 on this forward contract is $8. Using Black's model, find the price of a 9- months European put option with strike price of $103 on the same forward contract if the risk- free interest rate is 9%. Hint: you may want to compute implied volatility using trial-and-error method (make sure you compute it up to six decimal digit) A 1-year forward price on a stock is $100.
