LOS 66A - Calculate SD of 2 or 3 assets

What is the chance that Level 2 exam will make us calculate return/sd for a 3 asset portfolio?

not likely, I don’t think CFA would like their calculation that complex, especially consider the formula for SD calculation…

They have asked us to do in sample exam 2 or 3

They may ask to calculate for 2, but for a 3-asset one, it just becomes an algebra game, which isn’t the goal of CFAI.

there was a Q in sample 2, i was surprised. its the same thing as 2, takes maybe 30 more seconds. just gotta add in weights and std of the 3rd asset and then correlations between 1 and 3 and 2 and 3
