NO.PZ2017092702000095 问题如下 A call option on a stoinx is valueusing a three-step binomitree with up move thequals 1.05 ana wn move thequals 0.95. The current level of the inx is $190, anthe option exercise priis $200. If the option value is positive when the stopriexcee the exercise priexpiration an$0 otherwise, the number of terminnos with a positive payoff is: A.one. B.two. C.three. A is correct. Only the top no value of $219.9488 excee $200 题目中哪里确定的是 两层,即 先按照1.05 和0.95 先得到一层,然后再根据当前值 *1.05 得到了第三层的数据,就是怎么看出来第三层是terminal数据。
