问题如下：

An analyst has made the following return projections for each of three possible outcomes with an equal likelihood of occurrence:

If the analyst constructs two-asset portfolios that are equally-weighted, which pair of assets has the lowest expected standard deviation?

选项：

A.

Asset 1 and Asset 2.

B.

Asset 1 and Asset 3.

C.

Asset 2 and Asset 3.

解释：

C  is correct.

An equally weighted portfolio of Asset 2 and Asset 3 will have the lowest portfolio standard deviation, because for each outcome, the portfolio has the same expected return (they are perfectly negatively correlated).

我的计算器只能算到x2，y2呢，x3，y3怎么输啊

嗨，爱思考的PZer你好：


是的啊，先输入12，然后enter，就相当于让x=12了，然后再向下箭头。

嗨，从没放弃的小努力你好：


按向下箭头就可以正常输入x3 y3啊。


以A选项资产1 & 资产2的收益率相关性系数计算为例，打开金融计算器：

【2nd】【7】进入data模式，首先清除历史记录【2nd】【CLR WORK】

依次输入两组数据：X01=12【↓】Y01=12【↓】X02=0【↓】Y02=6【↓】X03=6【↓】Y03=0【↓】；

[2nd][8]进入STAT模式，一直按向下的箭头，直到出现r，r=0.5。说明两组数据的相关性系数=0.5。

同理，可以计算出资产1&资产3收益率的相关性系数为-0.5，资产2&资产3收益率的相关性系数为-1。

有关计算器的使用： 依次输入两组数据：X01=12之后，是不是要按enter? 我直接输入数据+向下箭头后，计算器一直显示X01,Y01, 没有进入X02, Y02.要怎么处理啊？
