ヾ(◍°∇°◍)ノ゙你好同学,
A 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:
1.以股票指数为标的资产的看涨期权,使用三期二叉树进行估值,上涨幅度=1.05,下跌=0.95。指数当前价格=190美元,期权行权价格=200美元。如果股指价格超过到期行权价格时,期权值为正值,否则为0美元,则具有正收益的末端节点有几个?
2.这个题目考的不是期权知识点,而考的是“二项分布”,是以期权为例应用了一下,题目是协会设置放在了概率章节,题目中也对期权的估值做了描述,当然衍生品如果学了之后做这题会更加顺手。
