问题如下:

If a Portfolio's SFR is 1.4 and  threshold level's return is  supposed to be 2%, what is the probability of return less than 2%?

选项:

A.

8.08%.

B.

30.20%.

C.

9.68%.

解释:

A is correct.

Using the table, we get F( -1.4) is 1 - 0.9192 = 8.08%.

为什么标准化时将Rp视为总体均值u?

同学你好,

portfolio return为E(Rp),由于“E”即expected value就是均值μ。所以在转化时就认为portfolio return为μ。
