2017-04-08 11:30A call option on a stock index is valued using a three-step binomial tree with an up move that equals 1.05 and a down move that equals 0.95. The current level of the index is $190, and the option exercise price is $200. If the option value is positive when the stock price exceeds the exercise price at expiration and $0 otherwise, the number of terminal nodes with a positive payoff is: A. one. B. two. C. three. 請問老師: “the stock index is valued using a three-step binomial tree"是什么含義?以及這道問題如何求解。謝謝!

學(xué)員你好,three-step binomial tree是三階二叉數(shù),如圖,每次分叉都會有上有下,向上就是乘1.05,向下就是成0.95,這樣三次過后總共會得到4種可能的結(jié)果,問題就問的是這四種可能的結(jié)果里有幾種是超過200的,顯然只有一種。
