和市场negative corelation

NO.PZ2024020101000004

问题如下:

Snohomish Mukilteo is a portfolio analyst for the Puyallup-Wenatchee Pension Fund (PWPF). PWPF’s investment committee (IC) asks Mukilteo to research adding hedge funds to the PWPF portfolio.The IC member also informs Mukilteo that for equity-related strategies, the IC considers low volatility to be more important than negative correlation. Based on what the IC considers important for equity-related strategies, which strategy should Mukilteo most likely avoid?

选项:

A.Long/short equity B.Equity market neutral C.Dedicated short selling and short biased

解释:

C is correct. For equity-related strategies, the IC considers low volatility to be more important than negative correlation. Dedicated short selling and short-biased strategies have return goals that are typically less than those for most other hedge fund strategies but with a negative correlation benefit. In addition, they are more volatile than a typical long/short equity hedge fund because of their short beta exposure. As a result, Mukilteo should avoid dedicated short selling and short-biased strategies.

题目中,IC在执行equity strategies时更看重的是low volatility,而不是negative 的correlation,而C选项中的两种策略都是和市场negative corelation,但是波动性是比较大的,因为头寸大都是只有short,所以C最不符合IC的要求。

和市场negative corelation的意思是,下跌的时候有正的收益吗?

嗨,爱思考的PZer你好:


同学的理解是对的哈,和市场的negative corelation的意思就是在市场下跌的时候有正的收益,所以对于short equity的策略一般都会有一个negative的correlation,但是这个投资者的主要目标并不是为了在市场下跌时有收益,而是希望volatility小,那么就是要beta小,long short策略的beta有一定的对冲作用,因此C选项的beta最大,所以最不可能采取的就是C的策略。
