这是公式哪个视频的内容

问题如下：

Which of the following transactions is the equivalent of a synthetic long call position?

选项：

Long asset, long put, short call

Long asset, long put, short bond

Short asset, long call, long bond

解释：

B is correct.

According to put−call parity, a synthetic call can be constructed by combining a long asset, long put, and short bond positions.

中文解析：

本题考察的是put call parity，P+S=C+K

合成call，需要把公式变形一下，所以得到C=P+S-K， -K就是short bond
