问题如下:

Which of the following strategies most likely meets Adams’ preferences?

选项:

A.Buy a payer swaption. B.Write a receiver swaption. C.Enter into a pay fixed swap.

解释:

Solution

A is correct. Adams would most likely buy a payer swaption. Although all three choices would hedge against rising interest rates, the potential losses on a payer swaption if rates fell would be limited to the option premium and would not be potentially large with uncertain timing.

B is incorrect because the potential loss on writing a receiver swaption if rates fell would be contingent on the interest rate and would be uncertain until termination of the contract.

C is incorrect because the amount of the potential loss if interest rates fell is contingent on the interest rate and would be uncertain until termination of the contract with a pay fixed swap.

A is correct. Adams would most likely buy a payer swaption. Although all three choices would hedge against rising interest rates, the potential losses on a payer swaption if rates fell would be limited to the option premium and would not be potentially large with uncertain timing.


为什么这么说呢?

嗨,爱思考的PZer你好:


protect the portfolio against an increase in interest rates but will not produce large losses if rates decrease.这句话意思是:选择的衍生品工具,能够在利率上升时,为原portfolio提供保护,在利率下降时,这个工具也不会产生大量亏损。翻译过来就是,利率上升时,这个衍生工具会盈利,抵消Portfolio的亏损,进而为portfolio提供保护;利率下降时,这个工具也不会产生亏损,此时原portfolio会盈利。显然,这是一个亏损有限、盈利无限的非对称结构的衍生品,也就是option。那么可以直接排除C。

 

来看A:buy payer swaption。利率上涨时,buy一方会选择行权,获利;利率下降时,Buy一方不会行权,此时损失有限的期权费。所以,利率上涨时,原portfolio有亏损,但buy payer swaption有盈利,可以抵消原portfolio的亏损,有保护作用;利率下降时,原portfolio有盈利,payer swaption不行权,只损失少量的期权费,没有large losses。

 

来看B:卖 receiver swaption。利率上涨时,买receiver swaption不会行权,那么卖receiver swaption一方获得优先的期权费;利率下跌时,买receiver swaption一方会行权,获利,那么此时卖receiver sawption一方会被动行权,有大额亏损。所以,卖receiver swaption会在利率下降时,会产生large losses,不符合A同学的预期。

 

来看C:进入pay fixed swap,利率下降,有亏损;利率上涨,有盈利,不满足利率下降时不会产生large losses的要求,所以也排除。

 

所以这道题选buy payer swaption
