这道题是怎么判断是用long还是short呢

NO.PZ2020012001000038

问题如下:

A company has a portfolio of stocks worth 1 million dollars with a beta of 1.5. An index futures price is currently at 3,000, and each contract is for delivery of 50 times the index. How many contracts are necessary to hedge the market risk of the portfolio? Should long or short contracts be used?

选项:

解释:

The number of contracts that should be shorted is

1.5 *1,000,000/(50 * 3,000)= 10

beta是正的意味着组合和大盘正相关,期货也是正相关,想调整到目标beta=0,那就要short。

嗨,努力学习的PZer你好:


题目说了现有的组合里有一百万的股票,beta是1.5,那意思就是现在的头寸时long的,那对冲它就要short index futures了。

为什么β是1.5就是long的,β是正数就代表是long的吗一开始
