Andrea considers constructing a synthetic long call position in PZ. Implementing the strategy would require him to :

选项:

A.

short shares of PZ.

B.

long a put option on PZ.

C.

short a call option on PZ.

解释:

B is correct.

To construct a synthetic long call position, Andrea would buy a put option on PZ. Of course, he would also need to long PZ shares to complete the synthetic long call position.

嗨,努力学习的PZer你好:


同学你好~

Long call 可以通过long stock + long put来合成,通过下图的图形和解释同学看一下是否可以理解哈~

(另外这道题目其他同学认为选项B应该加上long stock才完整,这是非常正确的哈,但是我们知道了long call可以通过 long stock和long put两个头寸来构成,而选项中只给出了一个头寸的信息,因此,我们就需要比对一下,很明显对于现货stock我们应该long,不是short,因此A错;对于put option,我们应该long,所以B对。而不包括call 这个头寸,所以C错)
