Level III Core · Asset Allocation to Alternative Investments
Alternative Investments in Asset Allocation for CFA Level III
Updated 8 October 2026 · Fact-checked
Alternative investments are assets outside traditional long-only stocks, bonds and cash: real assets, private capital, hedge funds and commodities. Investors add them for diversification and return enhancement. To solve questions, link each asset's traits (illiquidity, smoothed returns, fees, leverage) to the client's objectives and constraints, then judge whether it fits.
Understand Alternative Investments in Asset Allocation
Alternative investments cover assets that differ from traditional long-only public equities, bonds and cash. The main groups are real estate, infrastructure, natural resources (commodities, timberland, farmland), private equity, private debt, hedge funds and sometimes digital assets. Grouping varies by source, so focus on traits, not labels.
Why add them? There are two goals. The first is diversification: returns that are less than perfectly correlated with public markets can lower portfolio risk for a given return. The second is return enhancement: an illiquidity premium, manager skill (alpha), or exposure to risk factors not found in public markets. Some also offer inflation protection, such as real assets, or income.
But alternatives come with costs and traps. They are often illiquid, so you cannot sell quickly or at a known price. They have high fees (management plus performance fees), use leverage, and have limited transparency. Many are valued by appraisal or manager estimate, which creates smoothed returns. Smoothing understates volatility and correlation with public markets, so the diversification benefit looks better than it really is. Returns can also be non-normal, with negative skew and fat tails, and databases suffer from survivorship and backfill bias.
The exam asks you to fit the asset to the client. Check return objective, risk tolerance, liquidity needs, time horizon, and any legal, tax or governance limits. A long-horizon investor with stable cash flows and strong governance can hold more illiquid assets. A client with near-term spending needs or weak oversight capacity should hold less.
Finally, size matters. Allocate only after adjusting the inputs: unsmooth returns, account for fees and leverage, and stress the correlations. Then set a position size that survives a liquidity squeeze, such as capital calls for private funds during a market fall.
Key rules to remember
- Unsmoothing appraisal returns (first-order)
- r(true, t) = [r(obs, t) − φ × r(obs, t−1)] ÷ (1 − φ)
- φ is the smoothing parameter (0 ≤ φ < 1). Unsmoothed volatility is higher than observed volatility. Use only when the question gives φ.
- Portfolio variance, two assets
- σp² = w1²σ1² + w2²σ2² + 2 w1 w2 ρ σ1 σ2
- Lower correlation ρ means more diversification. Understated σ or ρ for alternatives overstates the benefit.
- Net return after fees
- Net return = Gross return − management fee − performance fee
- Performance fee = incentive rate × profit above any hurdle. Always compare alternatives on a net-of-fee basis.
- Leveraged return
- R(levered) = R(asset) + (D ÷ E) × [R(asset) − cost of debt]
- D ÷ E is debt to equity. Leverage magnifies losses as well as gains.
How to solve Alternative Investments in Asset Allocation questions
Use this sequence for any question on whether and how to include alternatives.
- 1Read the client's return objective, risk tolerance, liquidity needs, time horizon and constraints (legal, tax, governance, ESG).
- 2Identify the alternative category and list its key traits: liquidity, valuation method, fees, leverage, return drivers.
- 3State the role it could play: diversifier, return enhancer, inflation hedge, or income source.
- 4Check the data: are returns smoothed, survivorship-biased or net of fees? Adjust or flag it.
- 5Test fit against each constraint, especially liquidity and time horizon. Note capital-call and lock-up risk.
- 6Reach a clear recommendation (include, reduce, or avoid; and how much) and give one or two reasons tied to the client.
- 7Show any calculation clearly with the final number, and match the command word (calculate, justify, discuss).
Quickest way: Trait-to-constraint match
When to use it: Use for item set questions asking which alternative or allocation suits a client, or what a stated trait implies.
- Underline the client's binding constraint, usually liquidity or horizon.
- Ask: does the asset's illiquidity, fee level or leverage break it? If yes, eliminate it.
- If the data shows suspiciously low volatility or correlation, suspect smoothing.
- Choose the option that matches both the objective and the constraint.
Common mistakes in Alternative Investments in Asset Allocation
Treating observed alternative volatility and correlation as true risk.
Appraisal-based returns look stable, so the numbers seem reliable.
Fix: Say that smoothing understates risk and overstates diversification. Unsmooth the returns if a parameter is given.
Recommending alternatives only because they raise expected return.
Students focus on return and forget the client constraints.
Fix: Always test liquidity, horizon, governance and risk tolerance before recommending, and explain the match.
Ignoring fees and leverage when comparing with traditional assets.
Gross figures are quoted first.
Fix: Convert to net-of-fee returns and note that leverage raises both return and risk.
Forgetting illiquidity effects such as lock-ups and capital calls.
Students treat the allocation as a simple weight.
Fix: Mention that committed capital may be called when public assets are down, which can force sales and skew rebalancing.
Assuming all alternatives behave alike.
The word 'alternatives' groups very different assets.
Fix: Name the specific category and its own traits, for example real estate's income and inflation link versus hedge funds' strategy-dependent returns.
Worked examples
Example 1
An index of private real estate reports annual returns with standard deviation 6% and first-order smoothing φ = 0.5. The latest observed return is 8% and the prior-period observed return is 4%. Find the unsmoothed return for the latest period, and state what unsmoothing does to measured risk.
Show the solution
- Formula: r(true) = [r(obs,t) − φ × r(obs,t−1)] ÷ (1 − φ).
- Substitute: [8% − 0.5 × 4%] ÷ (1 − 0.5).
- Numerator: 8% − 2% = 6%.
- Divide: 6% ÷ 0.5 = 12%.
- Unsmoothing raises volatility, so the true risk is higher than 6% and diversification benefits are smaller than they appear.
Answer: Unsmoothed return = 12%. True volatility is higher than the observed 6%, so the apparent diversification benefit is overstated.
Example 2
A foundation has a 40-year horizon, stable donor inflows, a spending rate of 4% of assets and a strong investment committee. A board member proposes raising private equity and infrastructure from 10% to 30% of the portfolio. Recommend whether the foundation can support this, and justify it briefly.
Show the solution
- Objective: long-term real return to cover spending plus inflation. Private equity and infrastructure can offer an illiquidity premium and inflation linkage.
- Liquidity: spending is only 4% and donor inflows are stable, so liquidity needs are low.
- Horizon: 40 years suits long lock-ups.
- Governance: a strong committee can handle manager selection and due diligence.
- Risks: high fees, valuation smoothing and capital calls. Set the allocation so that a market fall still leaves enough liquid assets to meet spending and commitments.
Answer: Yes, the foundation can support a higher allocation, because its long horizon, low liquidity need and strong governance suit illiquid assets. It should size the 30% so liquid assets still cover spending and capital calls in a downturn, and judge returns net of fees and after unsmoothing.
Exam tips
- In constructed response, tie every reason to the client. A generic list of alternative traits earns few points.
- Match the command word: 'justify' needs a reason, 'calculate' needs the number shown, 'discuss' needs two or more linked points.
- When a question gives low volatility or low correlation for private assets, check for smoothing before accepting the diversification claim.
- Always mention liquidity and time horizon when sizing illiquid allocations.
- For item sets, eliminate options that ignore the binding constraint.

Alternative Investments in Asset Allocation: frequently asked questions
What are the main types of alternative investments?
The main groups are real estate, infrastructure, natural resources and commodities, private equity, private debt and hedge funds. Some frameworks also include digital assets. Focus on each group's liquidity, valuation and fee traits.
Why do investors include alternatives in strategic asset allocation?
They seek diversification, because returns may differ from public markets, and return enhancement through illiquidity premiums, manager skill or new risk exposures. Some also add inflation protection or income.
Why is smoothed returns data a problem?
Appraisal-based valuations lag market changes, so reported volatility and correlations are too low. This makes alternatives look safer and more diversifying than they are. Unsmoothing corrects this.
Do alternatives always reduce portfolio risk?
No. Correlations can rise in market stress, leverage adds risk, and illiquidity can force poorly timed decisions. The benefit depends on correct data, sizing and the client's constraints.
