I’m looking at the answer for this question on Schweser and absolutely don’t have a clue. Can anyone help? They’re asking for the intercept and come up with the answer of 0.155. The line: E(REF) = aEF + 0 + 0 + 0 = 0.12, so aEF = 0.155 (???) leaves me completely blank. If someone can explain this to me, that would help a LOT.
I emailed schweser on this and Jodi told me they used the formula from Question #8. Honestly, I’m still not getting it either. Sorry dude.
Thank god, I was looking at it and thought I lost it.
completely off the top of my head, i think the answers said that the intercept is the expected return from the APT model…is that what the answer to #8 was?
You can get it using APT model 4% + 5% * 1.5 + 2 % 2 % = 15.5 %
That’s Q8 disptra, on Q11 they ask you to give the intercept value. There the outcome is … 15,5% . haven’t got a clue why.
The intercept for a 2 factor macroeconomic model is the Expected return from APT thts how u use 15.5 % 
The line: E(REF) = aEF + 0 + 0 + 0 = 0.12, so aEF = 0.155 I saw that too and eventually concluded that the 0.12 is a typo. It would read: The line: E(REF) = aEF + 0 + 0 + 0 = 0.155, so aEF = 0.155
that is right. You can use APT to calculate intercept of macro model because intercept of marco model is expected return.

Yes. You can use CAPM as well. You can view CAPM as one factor APT in this context.
^^^Since CAPM E® was 10.4, this would have produced the incorrect answer in this case, no?
I think APT is generally better than CAPM. Since it is given, use APT first. I think Schweser does say use APT somewhere in the book.
