请问什么样的投资与历史表现和过去资产高关联？

问题如下：

An investor is seeking an investment that can take long and short positions, may use multi-strategies, and historically exhibits low correlation with a traditional investment portfolio. The investor’s goals will be best satisfied with an investment in:

选项：

A.

real estate.

B.

a hedge fund.

C.

a private equity fund.

解释：

B is correct. Hedge funds may use a variety of strategies (event-driven, relative value, macro and equity hedge),generally have a low correlation with traditional investments, and may take long and short positions.

三个选项中只有Hedge funds 能允许做空，可以采用同时做多、做空的操作；同时Hedge funds 投资策略包括有事件驱动、宏观驱动等多种策略，且整体与传统资产相关性较低。因此，综合来看只有B选项最符合题目的描述。
