Consider a European call option on a non-dividend-paying stock where the stock price is $100, the strike price is $120, the (annualized) risk-free rate is 2%, u = povst, d = 1/4, the (annualized) volatility is 20% per year, and the time to expiration is six months. A. Use a 10-timestep tree to determine the current market value of this six-month European call option. Do this manually by applying the Cox-Ross-Rubinstein framework, and be sure to show your work. B. What is the current market value of an otherwise identical (i.e., same underlying asset, same strike price, interest rate, same volatility, same number of timesteps, and time to expiration) European put option?
