FRM Part II · FRM Exam Part II · VaR and Risk Budgeting in Investment Management
A sponsor finds that its equity managers' active positions are all tilted toward small-cap value, so that a single factor drives most of the active risk. What is the most appropriate risk-budgeting response?
The sponsor should aggregate positions at the total plan level, identify the common small-cap value concentration, and adjust budgets or the manager mix. Individual tracking-error limits can all be met while the plan holds a concentrated, undiversified factor bet.
- ARely on each manager's tracking-error limit, since limits are respected individually
- BIncrease every manager's budget to improve diversification
- CAggregate positions at the total plan level, identify the concentration, and adjust budgets or manager mixCorrect
- DReplace tracking-error limits with a stop-loss rule for each manager
Explanation
Individual limits can all be respected while hidden factor concentration builds in aggregate. The sponsor must look through to total-plan exposures and adjust budgets or add managers with different exposures. Raising budgets would worsen concentration.
