问题如下:

Evelyn Weismann, a CFA Level I candidate, is a research analyst at Bay Area Investments, which specializes in derivatives and currency management. Bluerock Holdings, a US-based firm and an institutional client of Bay Area, is looking to increase its footprint in international markets. Bluerock is in the process of conducting due diligence to acquire Concord Associates, which is domiciled in London. Concord Associates has overall holdings amounting to GBP 400 million. Liam Mason, CEO of Bluerock, meets with Weismann and expresses his intention to mitigate the GBP currency risk before closing on the acquisition of Concord. Weismann makes the following three recommendations:

Recommendation 1: Implement an ATM call option on GBP/USD to protect the exposure against appreciation of the base currency.

Recommendation 2: Implement a risk reversal strategy by buying an ATM GBP/USD call option and buying an OTM GBP/USD put option.

Recommendation 3: Use a knock-in/knock-out option to receive an all-or-none asymmetric payoff when the exchange rate touches a pre-specified level.

Which of Weismann’s recommendations is most likely correct?

选项:

A.

Recommendation 1

B.

Recommendation 2

C.

Recommendation 3

解释:

Correct Answer: A

Recommendation 1 is correct.

If the base currency, USD, is appreciated against GBP, then the Concord Associates’ holdings of GBP 400 million will buy fewer USD in the future when the acquisition is completed.

The hedge is implemented in protecting against an appreciation of the base currency of the P/B quote, the USD. The hedge is established with an ATM call option (a long position in the USD).

P/B refers to the price of one unit of the base currency, “B,” expressed in terms of the price currency, “P.”

Recommendation 2 is incorrect.

Risk reversal, also referred to as a collar strategy, is created by buying stock and by simultaneously buying puts to protect the position against downside risk and selling calls to offset the cost.

Recommendation 3 is incorrect.

All-or-none asymmetric payoff is characteristic of a binary option and not a knock-in/knock-out option.

建议三不对的原因是hedge范围比较有限吗

嗨,努力学习的PZer你好:


同学,应该说All-or-none asymmetric payoff 是binary option特有的特征。只要是期权,payoff都是不对称的。

嗨,从没放弃的小努力你好:


不是,非对称不连续

所以all-or-none 这个描述不符 ,asymmetric 是符合的?

嗨,从没放弃的小努力你好:


不是,是错在all-or-none asymmetric payoff 是二元期权的特征,而不是knock-in/knock-out option的特征。

二元式期权是支付价值是离散数值(或非连续函数)的期权。常见的有“现金或者0”看涨期权。

此处有点超纲,咱们了解即可哈。
