Judge how efficiently a portfolio's structure serves its investment mandate

A portfolio is efficiently structured when its risks line up with the manager's claimed skills and the mandate's objectives and constraints. The test is to decompose active risk: how much comes from intended sources such as stock selection or chosen factor tilts, and how much from unintended ones such as sector, size or currency bets? A stock picker whose active risk is dominated by an accidental value or beta exposure is inefficient, because the client pays active fees for risk it could obtain cheaply. It should also respect the mandate's risk, liquidity and cost limits. A good recommendation neutralises unintended exposures, resizes positions so risk contributions match conviction, and cuts turnover that adds cost without adding alpha.
