AIP Portfolio Management & Asset Allocation 5 — Questions and Answers
Question 1: The Black-Litterman model improves on traditional mean-variance optimization primarily by:
- Eliminating the need for an expected return estimate
- Combining market equilibrium returns with investor views to reduce estimation error (Correct answer)
- Requiring only historical return data without subjective inputs
- Optimizing only for minimum variance regardless of return expectations
Correct answer: Combining market equilibrium returns with investor views to reduce estimation error
Black-Litterman blends CAPM-implied equilibrium returns with the manager's specific views, producing more stable and intuitive portfolio weights than raw optimization.
Question 2: A risk parity portfolio weights assets so that:
- Each asset contributes an equal dollar amount
- Each asset contributes an equal amount of risk to total portfolio risk (Correct answer)
- High-volatility assets receive the largest weights
- Weights are proportional to expected return
Correct answer: Each asset contributes an equal amount of risk to total portfolio risk
Risk parity equalizes each asset's marginal contribution to portfolio volatility, typically resulting in large allocations to low-risk assets like bonds and smaller equity allocations.
Question 3: Which of the following describes 'factor investing' or 'smart beta' as an asset allocation approach?
- Purely passive market-cap-weighted index replication
- Systematic exposure to return-driving factors like value, momentum, and quality (Correct answer)
- Discretionary stock picking based on analyst research
- Allocating exclusively to the minimum variance portfolio
Correct answer: Systematic exposure to return-driving factors like value, momentum, and quality
Factor or smart beta strategies systematically tilt portfolios toward well-documented return premia (value, size, momentum, quality, low volatility) using rules-based methodologies.
Question 4: An investor has a high liquidity need and a short time horizon. Which asset allocation adjustment is most appropriate compared to an investor with low liquidity needs?
- Increase allocation to illiquid private equity and real assets
- Shift toward liquid instruments such as short-duration bonds and money market funds (Correct answer)
- Maintain the same equity-heavy allocation for growth
- Increase exposure to long-duration bonds for higher yields
Correct answer: Shift toward liquid instruments such as short-duration bonds and money market funds
High liquidity needs require holding assets that can be quickly converted to cash without significant price impact, favoring short-duration and highly liquid instruments.
Question 5: What is the primary disadvantage of mean-variance optimization when applied in practice?
- It requires too few inputs to be practical
- It produces highly concentrated, unstable portfolios sensitive to small input changes (Correct answer)
- It cannot accommodate constraints such as short-selling restrictions
- It ignores correlations between assets
Correct answer: It produces highly concentrated, unstable portfolios sensitive to small input changes
MVO is notoriously sensitive to expected return estimates; small estimation errors can lead to extreme, unintuitive portfolio weights that change drastically with minor input adjustments.
Question 6: Which of the following is a key advantage of including Treasury Inflation-Protected Securities (TIPS) in a portfolio?
- They provide the highest nominal yield among fixed income securities
- Their principal adjusts with CPI, providing explicit inflation protection (Correct answer)
- They eliminate interest rate risk entirely
- They offer equity-like return potential with bond-like risk
Correct answer: Their principal adjusts with CPI, providing explicit inflation protection
TIPS principal is indexed to CPI, so the real value of principal and coupon payments is preserved even as inflation erodes the purchasing power of nominal bonds.
Question 7: In portfolio construction, 'tracking error' refers to:
- The difference between a portfolio's best and worst annual returns
- The standard deviation of the difference between portfolio and benchmark returns (Correct answer)
- The error in calculating portfolio NAV
- The deviation of individual security weights from equal-weight
Correct answer: The standard deviation of the difference between portfolio and benchmark returns
Tracking error quantifies how consistently a portfolio follows its benchmark; high tracking error indicates significant active deviation from the benchmark's return pattern.
