课后题解释

衍生品课后题第3个module第14题

Darden meets with Bhatt and learns that Bhatt will be moving back to his home

country of India next month to resume working as a commodity trader. Bhatt is

concerned about a possible US recession. His investment policy statement (IPS)

allows for flexibility in managing currency risk. Overall returns can be enhanced

by capturing opportunities between the US dollar and the Indian rupee (INR)

within a range of plus or minus 25% from the neutral position using forward con

tracts on the currency pair. C&M has a currency overlay team that can appropri

ately manage currency risk for Bhatt’s portfolio.

Determine the most appropriate currency management strategy for Bhatt. Justi

fy your response. 选择是被动策略\自由裁量策略\主动策略 中哪一个

答案是主动策略,答案的解释意思是25%的容忍度区间是太宽了所以不算自由裁量吗?没有看明白。

答案如下:Active currency management is the most appropriate currency management strategy because with this approach, the portfolio manager is supposed to take currency risks and manage them for profit with the primary goal of adding alpha to the portfolio through successful trading. This primary goal differs from the discretionary hedging approach in which the manager’s primary duty is to protect the portfolio from currency risk and secondarily seek alpha within limited bounds. While the difference between active currency management and discretionary hedging is one of emphasis more than degree, the bounded discretion that Bhatt has granted Darden (plus or minus 25% from the neutral position) strongly suggests that Darden is expected to take currency risk and seek alpha with priority over portfolio protection from currency risk.

嗨,爱思考的PZer你好:


是的,不过准确来讲,这个偏离幅度是多少能定义为active,在教材上是没有确切定义的。但是,我们做题的时候发现:经常出现的题干背景是IPS允许25%的偏离的时候,就可以认为适合采取主动管理的策略。而另一种常见的允许偏离IPS的范围是3%,这个范围被认为是小范围,应该采取的是discretionary的方法。


但是还是上面提到的,具体多少比例是active或者是discretionary的,教材没有说明,上面两个数据是我们根据例题总结出来的。在具体判断的时候可以这样来衡量:一般认为25%的偏离幅度是大的幅度适合主动管理,当然如果是更大的偏离幅度就更加确认是主动管理的;而3%的偏离是较小的幅度,或者是3%数字左右的单仍然是娇小的数字,就认为是适合discretionary的方法的。


另外,如果实在无法根据数字判断的时候就去看下题干中的其他信息,题目不会只给到我们一个数字的,还会关于投资者收益和风险偏好的其他表述,综合来看去判断到底是discretionary的还是active的哈。
