CFAI Morning 2008 question 4 - Corner Portfolios different, anything, anywhere, question, required

eagles_dare13

For anyone who has done this - they calculate the required return using he additive approach. If you use multiplicative, you get different weigfhts for the corner portfolios and the whole answer is wrong. Is there errate im missing? I dont see anything anywhere stating why they use additive and not multiplicative approach
Thanks

This is a clear fuck up IMO.  I have emailed them on their multiple other fuckups, and got no response.  I can only hope that they take this into account when grading, because typically when there is more than one answer the exam guildeline answers will show it, so this worries me because it makes no reference to multpile answers.

as I said before - CFAI exams guideline answers HAVE NO ERRATUM.
Even the other day someone sent a mail asking about the inflation before / after and received a rude email response back.
We are at their mercy out here
