问一道题:NO.PZ2018062016000095 [ CFA I ]

问题如下:

Using two-period binomial model, Jack wants to calculate the terminal value of a put option. If the current price of the underlying asset is $150 and the strike price is $120, the size of an up move is 1.69 and a down move is 0.59. Only when the price is below the strike price can the option has a positive value, otherwise the value will be zero. How many terminal nodes can give back positive return?

选项:

A.

1

B.

2

C.

0

解释:

A is correct. Only the third node has a value less than $120, which is $52.22.

二叉树的内容在quantitative这部分还没有讲,这题出来看的云里雾里,请问能不能解释下二叉树的内容?

视频里一般重点讲的是核心的知识点和考点,把所有词汇都面面俱到很难。随着学习的深入,总会遇到没有覆盖到的词汇或者非重点小概念。对于这种情况,从学习的角度出发,需要对题目做总结。基本上每做一道题遇到自己不熟悉的说法后,都需要总结一下协会会怎么做描述,进而进行记忆。例如这几个词汇,都没有经济学意义上的深层次含义,就是字面意思,这次看到了,下次遇到类似的说法就明白协会想表达的是什么了。

从做题的角度,如果遇到这种词汇把握不好,可以根据答案反推一下,这些练习题做错了都无所谓,把握知识点就可以。如果对于词汇或者某个小概念仍有疑惑的话,也可以进一步提问的。

好的谢谢老师解答

同学你好,

二叉树的内容在数量视频R9的“Discrete Distribution: Uniform Distribution and Binomial distribution”中有讲解。可以学习完后来做这道题,如果还有问题可以继续追问。

感谢回答,但在您所说章节中提及的二叉树问题和这道题中出现的up/down move和terminal nodes并没有在视频中出现,是不是可以建议增加到视频的例题中,不然确实拿到手第一反应是理解不能。
