We consider a 3-year forward binomial tree with steps of h = 1 year. The stock currently has a value of 41, and the values of the stock at t = h in the up and down nodes are, respectively, 59.95 and 32.90. What is the value of the volatility parameter that was used to construct this binomial tree? (A) There is not enough information to determine this parameter (B) 0.2 (C) 0.3 (D) 0.4 (E) 0.5
