# Asset Allocation and Security Selection

Hi,

Can someone explain me the intuition in regards to the below two formulas?  For example for asset allocation, why are we not choosing the active weight * portfolio returns and for security selection, why are we not choosing active returns* benchmark weights?

Asset Allocation: active weight * benchmark returns

Security Selection: Active returns * portfolio weights

Anyone??

asset allocation: could be between stocks and fixed income. If you want to check if the portfolio return is due to asset allocation. then, you would have to check weightings of stocks vs fixed income.

Security selection: is selecting stock a vs stock b. if you want to check if the portfolio return is due to security selection, then you would have to use active returns. Hope that helps.

I tried to do some problems, but i mix the formulas up and i think its because im not seeing the logic behind the formulas.

Asset Allocation: active weight * benchmark returns

Security Selection: Active returns * portfolio weights

Do you want intuition, or do you want understanding?

Simplify the complicated side; don't complify the simplicated side.

You can’t have both.

Intuition means that you get the correct answer without understanding.
