1. 014What is strategic asset allocation, and how much of the outcome does it really explain?Asset allocationIntermediatetechnicalMulti-assetAsset management

   Say this

   Strategic asset allocation is the long-run policy mix you would hold if you had no view, set from the objective and the constraints, and it explains most of the variation in a portfolio's returns over time. What it does not explain is the difference between two funds with the same policy mix.

   Then walk it

   1. Mechanically, it is a set of target weights and permitted ranges per asset class, agreed in an investment policy statement, with a benchmark for each sleeve and a rebalancing rule.
   2. It comes from the liability or the objective: required return, horizon, drawdown tolerance, liquidity needs, tax status, regulatory constraints. Not from a market view. The market view lives in the tactical overlay.
   3. The famous number is Brinson's, that about 90 percent of the variability of a fund's returns over time comes from the policy mix. That is routinely misquoted as 90 percent of the return level, which is wrong.
   4. Ibbotson and Kaplan cleaned this up: policy explains roughly 90 percent of the variation over time within a fund, about 40 percent of the variation across funds at a point in time, and slightly more than 100 percent of the level of return, because active management and costs net out negative on average.
   5. So the honest framing is: allocation dominates the risk profile and the path, and manager selection determines whether you beat your peers. Both matter, for different questions.
   6. Practically that is why governance time is best spent on the policy mix and the rebalancing rule, not on the monthly manager review. The decision with the largest effect is made once and revisited every three years.

   Where candidates lose it

   Quoting 'asset allocation explains 90 percent of returns'. It explains 90 percent of the variability over time, not the level, and the distinction is a standard trap in asset management interviews. Getting it right separates people who read the Brinson paper from people who read a marketing deck.

   • What inputs would you use for long-run expected returns?
2. 015A new institutional client hands you a mandate. How do you set the strategic asset allocation?Asset allocationIntermediatecase studyVanguardInvestment Research · Malvern · 2024

   Say this

   Start from the obligation, not the assets. What has to be paid, when, in what currency, and what shortfall is intolerable. Then build capital market assumptions, then solve for the cheapest mix that meets the obligation with acceptable risk, then write down the rules.

   Then walk it

   1. Define the objective precisely. A pension has a liability with a duration and an inflation linkage. An insurer has regulatory capital. An endowment has a spending rule. Each of those implies a different portfolio even at the same risk tolerance.
   2. Separate risk capacity from risk tolerance. Capacity is what the balance sheet or the funding position can absorb; tolerance is what the trustees will actually sit through. Build to the lower of the two, because a policy abandoned in a drawdown is worse than a more modest one that survives.
   3. Set capital market assumptions for each asset class: expected return, volatility, correlation. I would build expected returns from building blocks, real yields plus inflation for bonds, earnings yield plus growth for equities, rather than extrapolating history, because historical equity returns include a valuation re-rating that cannot repeat.
   4. Then optimise, but with a heavy hand on the inputs. Constrain sensible ranges, use resampling or shrinkage, and test the candidate mixes against the objective in a scenario framework rather than trusting one frontier.
   5. Then stress it. What does a 1970s inflation path, a 2008 correlation shock, or a decade of 2 percent real yields do to the funding position? A policy chosen on a single expected return path is untested.
   6. Then write the governance: target weights and ranges, the rebalancing rule, hedging policy for currency, liquidity budget, and review triggers. The document is the deliverable, because it is what stops the committee changing course at the worst moment.

   Where candidates lose it

   Going straight to weights, '60 percent equities, 40 percent bonds, done'. The sequence is objective, then capacity and tolerance, then capital market assumptions, then mix, then stress, then written policy. Also do not extrapolate historical equity returns as your expected return input; build it up from yield and growth and say so.

   Expect next

   • How would you build a long-run expected return for equities?
   • How does the answer change for a closed pension scheme?
   • What ranges would you set around the targets?

3. 016Does tactical asset allocation add value?Asset allocationHardsuperdayMulti-assetAsset allocation

   Say this

   On average, no. The evidence on discretionary market timing is poor and the fee and cost drag is certain. Where it has some support is systematic, valuation and momentum based tilts, run at small size around a strategic policy, with a hard discipline on when the view expires.

   Then walk it

   1. The problem is breadth. A tactical allocator makes a handful of independent bets a year, so even with a genuinely good hit rate, the fundamental law says the information ratio will be small. An equity manager making hundreds of decisions has a structural advantage.
   2. The evidence: most tactical funds underperform a static policy mix of the same risk, and dispersion between them is wide, which is what luck looks like. GTAA as a category has not delivered a persistent premium.
   3. What has some support: long-horizon valuation signals, CAPE-style, with a five to ten year horizon rather than a twelve month one; cross-asset momentum and trend following, which has a real and well-documented premium; and carry.
   4. Implementation matters more than the signal. Tactical shifts are cheapest expressed in futures and overlays, not by trading the underlying sleeves, and the cost of moving 5 percent of a large portfolio through cash equities can eat the whole expected edge.
   5. Governance is the thing that actually kills it. A committee that takes a view, sees it go against them for two quarters and reverses is guaranteed to lose money. Pre-commit to the horizon, the size and the exit condition.
   6. So my answer: keep the tactical range narrow, plus or minus 5 percentage points, run it systematically where possible, budget it explicitly against tracking error, and measure it separately so you can see whether it has earned anything. Most of the time the honest finding is that it has not.

   Where candidates lose it

   Enthusiastically saying yes and describing how you would read the macro. Interviewers in multi-asset seats have seen the attribution and know tactical is usually a small negative. The credible answer concedes the base rate first, then names the specific systematic signals that have evidence, then talks about governance and implementation cost.

   Expect next

   • What signals would you actually use?
   • How would you size a tactical tilt?
   • How would you measure whether the tactical overlay has added value?
4. 017What would your allocation be in today's market?Asset allocationHardtechnicalAmundiRates · London · 2018

   Say this

   Answer it as a portfolio, not a list of opinions. State the benchmark you are deviating from, give three or four tilts with a reason and a size for each, say what would make you wrong, and name the one risk that hurts every position at once.

   Then walk it

   1. Anchor first: 'against a 60/40 policy, I would run these deviations.' Without an anchor the answer is untestable and interviewers notice.
   2. Then the tilts, each with a mechanism. For example: neutral to modestly underweight developed equities on valuation with the earnings yield close to real bond yields, overweight duration where real yields are positive and inflation is converging to target, overweight investment grade credit over high yield because the spread per unit of leverage is better, and a small allocation to gold or trend following as the diversifier that does not depend on a correlation estimate.
   3. Size them. 'Plus 5 points duration, minus 3 equities, 3 in trend' is a portfolio. 'I like bonds' is a comment.
   4. Say the single dominant risk. In most current configurations it is that inflation re-accelerates, which hurts both legs of a 60/40 simultaneously, as 2022 showed. Name it and say what you hold against it, real assets or inflation-linked bonds.
   5. Then the falsifier and the horizon: what data would make you reverse, and when do you review. A view without an exit condition is a position you will hold too long.
   6. Close with honesty about the base rate: these are modest tilts because the evidence on tactical allocation is weak, so the policy mix is doing most of the work. That framing reads as professional rather than hesitant.

   Where candidates lose it

   Delivering a macro monologue with no benchmark, no sizes and no falsifier. The interviewer is testing whether you think in portfolios and whether you have actually looked at the current numbers. Know today's ten year yield, the index forward multiple and where credit spreads are, or the answer collapses on the first follow-up.

   Expect next

   • Where is the ten year yield right now?
   • What would make you reverse the duration call?
   • How would you express that view in instruments?

5. 018How would you invest ten million pounds?Asset allocationIntermediatetechnicalSCSchrodersAsset Management · London · 2023

   Say this

   My first move is to ask whose money it is and what it has to do, because the same ten million belongs in completely different portfolios depending on the answer. Then I would build a low-cost core, add satellites only where I can justify an edge, and write down the rebalancing rule.

   Then walk it

   1. Ask four questions: what is the money for, when is it needed, what loss would force a change of plan, and what tax wrapper and jurisdiction are we in. Volunteering those questions is most of the marks on this question.
   2. Assume a long-horizon investor with no near-term call on the money. I would run something like 55 to 65 percent global equities, broadly market weighted with a modest home bias for currency reasons, 20 to 25 percent high quality duration, 5 to 10 percent inflation-linked or real assets, and a working cash buffer.
   3. Build the core passively. At ten million, total cost matters more than cleverness: a global tracker at under 10 basis points versus an active fund at 80 basis points is a certain 70 basis points a year of advantage, which compounds to real money over twenty years.
   4. Use satellites sparingly and only where there is a reason: small cap and emerging market inefficiency, credit where the manager can hold to maturity, trend following as a diversifier. Cap the total satellite sleeve so a bad manager choice cannot break the plan.
   5. Then the practicalities, which is where candidates win this question: tax wrappers first, staged entry over a few months if the money arrived as a lump sum, currency hedging policy on the bond sleeve, and a rebalancing rule with 5 percentage point bands.
   6. And the caveat: if the money is earmarked for something in three years, most of this is wrong and the answer is short-dated bonds and cash. Say that, because it shows the horizon is driving the portfolio rather than your product preferences.

   Where candidates lose it

   Launching into a product list before asking what the money is for. This is a test of process, and the specific distinction that separates good answers is horizon and purpose driving the mix. Also, give real numbers. A candidate who cannot commit to approximate weights sounds like they have never built a portfolio.

   Expect next

   • How would that change if the client needs the money in three years?
   • Would you invest it all at once or phase it in?
   • Where would you actually use an active manager?

6. 019What would you include in a multi-asset fund right now, choosing from every asset class including fund of funds?Asset allocationHardsuperdayNeuberger BermanPrivate Equity · London · 2022

   Say this

   I would build it in three layers: a cheap beta core, a set of diversifying return streams, and an illiquidity sleeve sized to the liquidity budget rather than to the expected return. And I would be sceptical of fund of funds, because the second fee layer has to be earned.

   Then walk it

   1. Layer one, core beta, roughly two thirds: global developed and emerging equity, government duration, investment grade credit, all passive or near-passive. This is where the return comes from and it should cost almost nothing.
   2. Layer two, diversifiers: trend following or managed futures, which has genuine crisis convexity, some carry and relative value, and inflation-sensitive real assets. The test for anything in this layer is correlation to the core in stressed periods, not standalone Sharpe.
   3. Layer three, illiquids: private credit, secondaries, infrastructure, property. Sized by the liquidity budget. The question I would answer first is how much of the fund can be locked up given redemption terms, and only then which managers.
   4. On fund of funds: it buys access, diversification and diligence, and it costs an extra layer, often 60 to 100 basis points plus a share of carry. That can be worth it for a small investor entering private markets for the first time, or for hedge fund selection where diligence is genuinely hard. It is bad value for anyone with the governance to select directly, and secondaries or co-investment usually do the same job cheaper.
   5. Then check the whole thing for hidden duplication. Private credit, high yield and equity beta are all long the same cycle. The portfolio can look like eight sleeves and behave like two.
   6. And name the liquidity mismatch explicitly. A daily dealing multi-asset fund with 20 percent illiquids has a structural problem in a redemption wave, which is what gated UK property funds in 2016 and 2020.

   Where candidates lose it

   Producing a shopping list of asset classes with no organising logic and no view on the fee stack. The question names fund of funds on purpose, so have a real position on whether the second layer of fees earns its keep. And mention liquidity mismatch, because a multi-asset fund that cannot meet redemptions is the failure mode this seat actually worries about.

   Expect next

   • How would you size the illiquid sleeve?
   • When is a fund of funds actually the right answer?
   • How would you assess one of those underlying funds?

7. 020What risk and return targets would you set for an institutional investor?Asset allocationHardcase studyMSCIRisk Management · Remote · 2013

   Say this

   Derive them, do not pick them. The return target comes from what the institution has to fund, in real terms. The risk target is the largest loss that does not break the institution, expressed as drawdown and funded status rather than volatility alone.

   Then walk it

   1. Start with the required return. A pension needs the discount rate on its liabilities plus whatever deficit repair is needed; an endowment needs its spending rate plus inflation plus costs, so a 4.5 percent spend plus 3 percent inflation plus 0.5 percent costs implies about 8 percent nominal.
   2. Then test whether that is achievable from the capital market assumptions. If the required return is 8 percent and your assumptions give 6.5 percent for a portfolio at the risk limit, the honest output is that the spending rule or the contribution rate must change. Saying that is the professional answer.
   3. Then the risk side, in the institution's own units: probability of the funding ratio falling below 90 percent, maximum acceptable drawdown, shortfall risk against the liability, and a liquidity floor for benefit payments or capital calls.
   4. Express the active risk separately. Total portfolio volatility of perhaps 9 to 11 percent for a typical balanced institution, with a tracking error budget against the policy benchmark of maybe 1 to 2 percent, allocated between tactical tilts and manager risk.
   5. Then set the horizon and the measurement convention. Targets over rolling five years, not calendar quarters, otherwise the governance process will force short-termism no matter what the document says.
   6. And a completeness check: are the targets internally consistent? A 9 percent return target with a 10 percent maximum drawdown limit is not a mandate, it is a contradiction, and the job is to say so before the money is invested.

   Where candidates lose it

   Naming numbers with no derivation, '8 percent return, 12 percent volatility'. The interviewer wants to see the target come from the liability and the risk limit come from what the institution can survive. And if the required return is not achievable, say so rather than quietly raising the risk to make the arithmetic work.

   Expect next

   • What if the required return is not achievable at that risk level?
   • How would you express risk to a trustee who does not know what volatility means?
   • How would you split the tracking error budget?

8. 021How do private assets fit into a strategic asset allocation when they are only valued quarterly?Asset allocationIntermediatetechnicalMulti-assetInstitutional asset management

   Say this

   You have to unsmooth the returns before they go anywhere near an optimiser, otherwise the quarterly marks make private assets look like low-volatility, low-correlation magic and the optimiser puts everything there. Then size them off the liquidity budget, not off the expected return.

   Then walk it

   1. The measurement problem: appraisal-based or model-based marks are stale and averaged, so reported volatility is understated and correlation to listed markets is understated too. Private equity marked quarterly shows maybe 10 percent volatility when the underlying economic exposure is levered equity at 25 percent or more.
   2. So unsmooth. The standard approach is to regress reported returns on current and lagged public returns and sum the betas, or to use a listed proxy plus leverage as the economic exposure. You will usually find a private equity sleeve behaves like 1.2 to 1.4 times small cap equity.
   3. Then the optimiser gives sensible answers. Feed it raw private marks and it will recommend 60 percent private assets every time, which is the single most common abuse of mean-variance in institutional investing.
   4. Size by liquidity. Work out committed capital, the drawdown schedule, expected distributions and the worst case where distributions stop for two years while calls continue. That denominator problem is what forced endowments into secondaries at discounts in 2009 and again in 2022.
   5. Then decide what you are actually buying: an illiquidity premium, access to companies not available publicly, and manager selection dispersion that is genuinely wide in private markets. Not diversification, because the economic exposure is the same cycle.
   6. And the honest caveat about the reported numbers: IRRs are money-weighted and subscription lines flatter them, so I would compare a private fund on a public market equivalent basis rather than on headline IRR.

   Where candidates lose it

   Treating reported private asset volatility as real, which makes the optimiser allocate everything to them. The two things that must appear are unsmoothing the returns and sizing off the liquidity budget including the denominator effect. Calling private assets a diversifier without qualification is the tell that a candidate has only seen marketing material.

   Expect next

   • What is the denominator effect?
   • How would you compare a private fund to public equity?
   • How much of a portfolio can be illiquid?
9. 022You are looking at real estate exposure across a portfolio. How would you treat different property types differently?Asset allocationHardcase studyGoldman SachsAsset Management · Dallas · 2026

   Say this

   Split them by lease length and by what drives demand, because that is what determines whether a property behaves like a bond, like equity, or like an operating business. Then underwrite each on its own risk: obsolescence, capex intensity, tenant credit and refinancing.

   Then walk it

   1. Long-lease, single-tenant, investment grade covenant assets are essentially credit with a residual. Value moves with rates and the tenant's spread, so I would treat them as long-duration bond substitutes and measure their rate sensitivity explicitly.
   2. Short-lease operating assets, hotels and self-storage, reprice every night or every month. They are the most inflation-responsive and the most cyclical, so they behave like equity with high operating leverage.
   3. Industrial and logistics is a structural demand story, e-commerce and supply-chain onshoring, with short capex cycles and modest obsolescence. Residential is defensive, granular tenant credit, and often politically exposed through rent regulation.
   4. Offices are the obsolescence case. The split is not offices versus non-offices, it is prime with a capex budget versus secondary that will need enormous spend to stay lettable. Cap rate alone hides that, so I would underwrite the capex to keep the asset competitive and the realistic terminal vacancy.
   5. Retail is bifurcated in exactly the same way: dominant destination centres with footfall have repriced and now yield well; secondary high street is a melting ice cube.
   6. Across all of them, the two numbers I would prioritise are the debt maturity wall and the spread of the exit yield over the cost of debt. Most real estate losses come from refinancing at a higher rate against a lower valuation, not from the tenant defaulting.

   Where candidates lose it

   Discussing real estate as one asset class with one cap rate. The interviewer named property types deliberately, so the answer must differentiate by lease length, capex intensity and obsolescence. And name the refinancing risk, because in a higher rate environment that is where the actual losses sit.

10. 023Would you allocate to retail real estate today, and why?Asset allocationIntermediatetechnicalNUNuveenInvestment Management · New York · 2021

    Say this

    Selectively yes, and the reason is that the sector already took its pain, so pricing reflects the structural problem in a way it does not in some other property types. But only the dominant assets, and only with a view on the capex and tenant mix.

    Then walk it

    1. State the structural case against first, because the interviewer is testing whether you will be honest: e-commerce took share, rents on secondary centres are still resetting downwards, and retail needs continuous capital to stay relevant.
    2. The investable case is bifurcation. Grocery-anchored and necessity retail has proved resilient through both the pandemic and the rate shock, because footfall is non-discretionary and leases are short enough to reprice with inflation.
    3. Then the pricing argument, which is the whole point. Retail derated from 2016 onwards, years before offices did, so entry yields already price a bad outcome. Buying a repriced asset class with a known problem is often better risk-adjusted than buying one whose problem has not been marked yet.
    4. What I would underwrite: tenant sales productivity and occupancy cost ratio, because that tells you whether the rent is actually affordable to the tenant, the capex required per square foot to keep the asset trading, and the covenant quality of the top ten tenants.
    5. What I would avoid: secondary and tertiary centres in declining catchments, and anything where the exit assumes a cap rate tighter than entry. If the return depends on yield compression rather than on income, it is a rates bet wearing a property costume.
    6. So the position: a modest allocation to dominant grocery-anchored and outlet formats bought on income, funded out of the office allocation rather than out of logistics, with the debt maturity profile matched so I am never a forced seller.

    Where candidates lose it

    Answering with a sector narrative and no price. Everyone knows e-commerce hurt retail; the question is whether that is already in the entry yield. A candidate who cannot say what they would underwrite at the asset level, occupancy cost ratio and capex per square foot, is giving a newspaper answer.

    Expect next

    • What yield would you need to buy a secondary centre?
    • How would you fund that allocation?
    • Does listed retail REIT pricing tell you anything useful here?
