问题如下：
Owen and Yang meet with Callie Steven, an upper
level executive with AutoPay, a small but fast growing privately held company.
She has been employed with AutoPay for more than 15 years and as a result, her
holdings in AutoPay are estimated to be more than 30% of her total portfolio.
She believes that over the next several years AutoPay will put together an
initial public offering, resulting in a huge windfall. She states that she has
a significant portion of her portfolio in short-term bonds and money market
funds to offset the risk of her AutoPay shares. Owen points out to Steven that
her current portfolio is subject to mental accounting, is not constructed in
layers, and does not take into consideration covariance between assets.
Is Owen’s comment regarding
Steven’s current portfolio correct?
选项：
A.No, he is incorrect with
regard to portfolio construction
Yes
C.No, he incorrect with regard
to covariance between assets
解释：
A is correct.
Owen’s comment regarding Steven’s current portfolio construction is not correct. Her current portfolio is subject to mental accounting, has been constructed in layers and does not take into consideration covariance between assets.
這題出現在講義的哪邊嗎 我在講義81頁 沒有看到關於covariance的敘述，我對這一題產生了很大的疑問就是：
1)所以根據先前的回答，分層的依據不僅僅只有錢的來源和目標，也就是說我如果想要以家人來區分也可以算是mental accounting嗎？
2)有辦法用老師上課的思路講解一下這一題嗎 看了之前的答案還是不太明白，又不想隨便混過去 謝謝
