Issues: Reading 5 practice question

Hi, guys. I am reading the textbook about behavioral finance. In practice question of reading 5, I do not agree with the solutions of questions 6. 

[question removed by moderator]

My understanding: I agree that the statement IS talking about mean-variance stuffs BUT it is a subjective claim from a client, NOT from a systematically statistical analysis. The client’s saying, “willing to take a small chance”, means personal experience or emotional judges like 8% loss is his bottom line. I think it should be related to layers and behavioral portfolio theory that allocates funds based on mental accounting.

Please give some advice.

He does not talk about different portfolios - 1 single portfolio.

Where are the layers you are talking about … when you say / talk about your answer ?

CP

First of all, thank you for the response.

So you are saying that 1 single portfolio cannot have layers? 

I don’t think so. Like the example 3 in section 4.3.3. of reading 5, one portfolio can contains 3 layers or more if you wish. I think the statement is somehow much closer to the example in the textbook. 

Please share your more opinion. Thanks!

I am not saying that …

Portfolio may have layers - but he is looking at the PORTFOLIO as a whole when he says 8% is his target Return objective. (Not a particular Layer’s)

“Expected return – 1.645 × Expected standard deviation ≥ –8%.” 

FOR THE FULL PORTFOLIO not for a Layer within the Portfolio.

I agree with cpk123.  mental accounting breaks the portfolio into layers and manages the portfolio as individual layers versus a total portfolio / total return view point.  As an example, living expenses could be one layer, college education another, gambling a third, vacations a forth, and so on.  a mental accounting bias would view each layer independently and have different risk/return characteristics for each.  

Thank you cpk123. 

Now I have found the correct angle to understand this statement. 

Appreciate it so much!
