问题如下:

The specialist hedge fund strategy that Mukilteo plans to recommend is most likely

选项:

A.cross-asset volatility trading between the US and Japanese markets. B.selling equity volatility and collecting the volatility risk premium. C.buying longer-dated out-of-the-money options on VIX index futures

解释:

C is correct. Mukilteo needs to recommend a specialist hedge fund strategy that can help PWPF maintain a high Sharpe ratio even in a crisis when equity markets fall. Buying longer-dated out-of-the-money options on VIX index futures is a long equity volatility position that works as a protective hedge, particularly in an equity market crisis when volatility spikes and equity prices fall. A long volatility strategy is a useful potential diversifier for long equity investments (albeit at the cost of the option premium paid by the volatility buyer). Because equity volatility is approximately 80% negatively correlated with equity market returns, a long position in equity volatility can substantially reduce the portfolio’s standard deviation, which would serve to increase its Sharpe ratio. Longer-dated options will have more absolute exposure to volatility levels (i.e., vega exposure) than shorter-dated options, and out-of-the-money options will typically trade at higher implied volatility levels than at-the-money options.

做两个

嗨,爱思考的PZer你好:


它这个策略的核心是要在市场危机的时候能够有比较高的收益,而市场危机证明未来的波动性会上升,所以long VIX futures能够在波动率上升的时候获得收益。

而A策略涉及的是利用两个市场之间的volatility差异来进行套利,并没有涉及到危机的情况,所以是不符合的。
