STAT/ACTSC 446/846 Assignment #2 - Additional Information (as of Oct. 5) Some additional information/minor changes for the following exercises on the binomial model: Ex 10.6 and 10.7 Since we are asking you to use n = 4 instead of n = 2, you should also change T = 1 to T = 2, so that the size h of the time-steps remain the same (and hence u and d also stay the same). Ex 10.12 (take δ = 3% instead of δ = 0, n = 3 instead of n = 2, and T = 1 year instead of 0.5 year).Take u = e σ T/n = e 0 . 3 1 / 3 = 1 . 19 and d = e - σ T/n = e - 0 . 3 1 / 3 = 0 . 84. a) Compute the call price (of a European Call). b) Compute the put price (of a European put). Don’t do the American put. Ex 11.9 (Use an Excel spreadsheet for this problem). Use a binomial tree with

For the 1-year and 2-year maturities, you only need to report the composition of the replicating portfolio for the two rst nodes. b) Comment the eect of the maturity on the option price (you do not have to compute the expected return on the option)....
