I think you need the “what” AND “why” long time horizon (what) - allows time for the endowment investment portfolio recover from any shortfall or negative returna in any given year (why)
I would be interested to learn if a short answer like OP is sufficient. I have been ducking points, though I hit on “key words”, because it seems the CFA answers are a lot more elaborate than mine.
but i understand they’re longer because they also explain to us everything regarding the answer in order for us to understand the answer. But it is very clear in stating the points you need to check in order to have the answer correct, am I wrong?
I think if they ask to “give a reason” --> means just a case example without “why”. We need to exapand the answer with “why” part only if they ask to “explain”…
That is exactly what I’m also asking myself. I mostly get the answers correct, they are just waaaaay shorter than the guideline answers and not as elaborate linguistically. Given the only 3-4 minutes available for most sub-questions I can’t see myself writing down much more than that.
