老师，我用计算器摁出来是error4。。我已经摁过好几次了，您方便发一个详细的计算器截图吗

  1. CFA I
  2. Portfolio

NO.PZ2015121801000067

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).

x1 y1 x2 y2 x3y3

嗨，努力学习的PZer你好：


试一下直接按“2nd+ENTER”，即调用“SET”功能。

正常按一下后，计算器中的“1-V”就应该变成“LIN”（如果不是，就多按几次2nd+ENTER，直到出现LIN为止）。在“LIN”模式下输入计算器即可。应该就不会再出现error4的问题了。
