1. 013A manager has beaten the index for five years, but the returns load heavily on momentum. What do you do?Factor modelsHardcase studyMulti-manager allocationFund selection

   Say this

   You do not fire them for having a factor tilt, you reprice them. If the excess return is momentum beta, you can buy that exposure for maybe 25 basis points, so the question becomes what is left after the factor and whether the fee is justified by that residual.

   Then walk it

   1. Quantify it first. Run the fund on market, size, value, momentum and quality, and split the excess return into factor contribution and intercept. If 80 percent of the 3 percent excess is momentum loading, the true alpha is 60 basis points before fees.
   2. Compare that to the replication cost. A momentum ETF or a swap on the factor costs a fraction of an active fee. If the manager charges 90 basis points for 60 of residual, the client is paying for beta that is available cheaply.
   3. Then ask whether the loading is intentional. A manager who says 'we buy businesses with improving fundamentals and yes, that looks like momentum' is coherent. One who claims pure bottom-up stock picking while the regression says otherwise has a process-outcome mismatch, which is the actual red flag.
   4. Then check the portfolio context. If I already hold two momentum-heavy managers, this one is redundant regardless of its standalone quality. Correlation of active returns across managers is what determines whether the roster adds anything.
   5. Then the risk question. Momentum has periodic violent crashes, 2009 being the classic, so a portfolio unknowingly stacked on it has a fat left tail that will not appear in the trailing five year statistics.
   6. My action: renegotiate the fee or the mandate, hedge the factor centrally if I want the residual, and if neither is possible, replace the position with the cheap factor and spend the saved fee budget on a manager whose alpha is not replicable.

   Where candidates lose it

   Answering either 'great track record, allocate' or 'it is just factor beta, fire them'. Neither is a decision. The professional answer prices the replicable part, tests whether the exposure is intentional, and checks redundancy against the existing roster.

   • How would you hedge the momentum exposure?
   • What if the manager says momentum is their stated process?
   • How long a record would you need to be confident in the residual?
2. 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?

3. 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?

4. 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.

   Expect next

   • How would you underwrite an office asset today?
   • How does listed REIT pricing help you value a private book?
   • Where does the debt sit in your analysis?

5. 033Your analysts give you return forecasts with wildly different levels of confidence. How do you build the portfolio?Portfolio constructionHardcase studyMulti-assetFundamental asset management

   Say this

   Make the confidence an input rather than a footnote. Convert each forecast into a signal with a dispersion attached, scale positions by the ratio of the expected return to its uncertainty, and let low-confidence views sit near benchmark weight instead of arguing them down qualitatively.

   Then walk it

   1. First, standardise the forecasts so they are comparable. Analysts express things differently, so I would convert everything to expected excess return over the same horizon, then to a z-score within the coverage universe.
   2. Then attach dispersion. Ask each analyst for a bear and bull case, not just a target, and use the spread as the uncertainty estimate. Position size then scales with expected return divided by variance, which is the Black-Litterman intuition applied at the stock level.
   3. Then adjust for track record rather than confidence expressed. Confidence and accuracy are barely correlated, and the analyst who sounds most certain is often the most overfitted. If I have hit rate data by analyst and by sector, I would shrink each forecast toward zero in proportion to their historical noise.
   4. Then handle correlation between views. Five high-conviction calls that all require the same rate path are one position. I would run the proposed portfolio through a factor model before trading, and cut the aggregate exposure rather than any single name.
   5. Then cap the damage. A hard maximum active weight regardless of stated conviction, because the largest single loss in a fundamental book usually comes from the position everyone agreed about.
   6. The organisational part matters too: if analysts learn that stated confidence drives sizing, confidence inflates. So the sizing rule should use the bear case and the historical accuracy, which are harder to game than a stated conviction score.

   Where candidates lose it

   Answering 'size by conviction' without saying how conviction becomes a number, or ignoring that stated confidence is gameable and uncorrelated with accuracy. The strong answer uses the bear case as the uncertainty measure, shrinks by track record, and aggregates the views through a factor model before trading.

   Expect next

   • How would you measure an analyst's hit rate?
   • What if the highest conviction ideas are all correlated?
   • Would you ever override the sizing rule?
6. 058You are assessing exposure to EMEA real estate debt across the portfolio as eurozone rates shift. How would you judge attractiveness and which risk factors would you prioritise?Fixed income and LDIHardcase studyPIMCOReal Estate · Munich · 2024

   Say this

   Judge it on spread per unit of attachment risk, not on headline yield. The two numbers I would lead with are loan to value against a marked-down, not appraised, collateral value, and the debt yield, net operating income over loan amount, because that is the one metric that does not depend on a cap rate assumption.

   Then walk it

   1. Attractiveness framework: all-in yield equals the base rate plus spread, so first split how much of the return is just Euribor. If two thirds of a 9 percent coupon is the base rate, you are being paid 300 basis points for real estate credit risk, and that should be compared to corporate high yield at similar rating, not to the 2021 version of itself.
   2. Then the structural position. Senior versus mezzanine versus whole loan, and the attachment point. Senior at 55 percent LTV on a re-marked value is a genuinely different asset from mezzanine at 60 to 75 percent, and in a market where values have fallen 20 to 30 percent the second one may already be impaired.
   3. Prioritised risk factor one, refinancing and the maturity wall. European CRE loans written at 1 percent base rates and 60 percent LTV now face refinancing at 3 to 4 percent with lower valuations, so the borrower has a funding gap. That gap, not tenant default, is the source of most losses.
   4. Factor two, valuation lag. Appraisal-based values move slowly and transaction evidence is thin in a frozen market, so I would triangulate with listed REIT implied cap rates and with actual completed transactions, and underwrite to that rather than to the last valuation report.
   5. Factor three, debt yield and interest coverage at current rates. An ICR that was 2.5 times at origination on a floating loan can be below 1.2 now, which is where covenant breaches and cash traps start.
   6. Factor four, the collateral's own quality: sector, obsolescence and capex requirement, particularly energy performance rules in Germany and the Netherlands, which can strand an asset. Then jurisdiction, because enforcement timelines vary enormously across EMEA and a two-year workout in one country is a six-month process in another.
   7. The conclusion I would give: senior EMEA real estate debt at conservative LTVs on re-marked values is attractive because banks have retreated and the spread reflects illiquidity more than credit, while subordinate positions on 2021 valuations are where I would expect the losses.

   Where candidates lose it

   Answering with a rates view and a yield number. The interviewer wants credit underwriting at the loan level: attachment point, debt yield, interest coverage at today's base rate, and the refinancing gap. Quoting appraisal LTVs without re-marking the collateral is the mistake that made 2023 painful for a lot of real estate credit books.

   Expect next

   • Why do you prefer debt yield to LTV?
   • How would you re-mark a German office valuation?
   • Where in the capital structure would you actually invest?

7. 065You need to move five percent of a two billion dollar portfolio into small caps. How do you do it?Implementation and costsHardcase studyPortfolio implementationInstitutional asset management

   Say this

   One hundred million into small caps is a large order relative to the liquidity, so I would get the exposure on quickly with a liquid instrument and then transition into the physical portfolio slowly. Beta first, alpha second, and measure the whole thing as implementation shortfall.

   Then walk it

   1. First, size the problem honestly. One hundred million spread across, say, 80 small cap names is 1.25 million per name. If the median name trades 5 million a day, each position is a quarter of a day's volume, so trading at 10 to 15 percent of volume means a week or more and material impact.
   2. Day one: buy small cap index futures or an ETF to get the exposure immediately. That removes the risk of being underweight while you trade, which is usually a bigger risk than the impact cost, and it costs a few basis points.
   3. Then transition into physicals over one to three weeks with a participation strategy, trading a fixed low percentage of volume, being opportunistic with liquidity rather than mechanical, and selling the futures down as physicals fill.
   4. Fund it in the cheapest place. If the money is coming out of large cap, sell large cap futures or use a transition manager to cross where possible, rather than selling physicals into the market on both legs. Crossing internally against another fund at the mid, where the mandate allows, is free.
   5. Pre-trade analytics matter here: expected cost by name, a liquidity screen that excludes anything where the position would exceed a few days of volume, and a plan for the tail of the order, which always takes longer than the model says.
   6. Then measure it against the decision price, not the arrival price, and report the shortfall including the futures basis. If the all-in cost came to 60 basis points on 100 million, that is 600,000 dollars spent to implement one allocation decision, and the allocation needs to be expected to earn a good deal more than that to be worth doing. Saying that out loud is the mark of someone who thinks about net returns.

   Where candidates lose it

   Answering 'phase it in over time' with no instrument and no numbers. The expected structure is synthetic exposure first, physical transition second, funded through the cheapest leg, with an explicit cost estimate. And connect it back to the decision: if implementation costs 60 basis points, the allocation has to clear that hurdle.

   Expect next

   • What if there is no liquid small cap future in that market?
   • How would you decide the participation rate?
   • Would you use a transition manager?
8. 094Pitch me something you would put in the portfolio, and tell me how you would size it.Career and fitHardsuperdayWMWellington ManagementPortfolio Management · Boston · 2019SCSchrodersInvestment Management · London · 2024Apollo Global ManagementInvestments · Remote · 2021

   Say this

   Lead with the recommendation, the variant view and the number, then the sizing. In a portfolio seat the sizing is half the question, so say what it displaces, what the bear case costs you, and how much of the risk budget it uses.

   Then walk it

   1. Thirty seconds of thesis: what it is, what the market believes, what you believe instead, and why that gap exists. Then the target and the path, with one or two numbers you can defend, not a full model walk-through.
   2. Then the falsifier, unprompted. 'I am wrong if gross margin does not reach X by the second half, and that is testable in two quarters.' A thesis with a date and a number is a professional thesis.
   3. Then the bear case quantified, because it drives the sizing. If the downside is minus 35 percent and I am willing to risk 1.5 percent of the fund on any single name, the position caps at roughly 4 percent.
   4. Then the portfolio fit, which is what makes this a portfolio management answer rather than a stock pitch. What factor and sector exposure does it add, what does it duplicate in the existing book, and what am I selling to fund it.
   5. Then liquidity and capacity: days of average volume for the intended position, and how long an exit would take in a stressed market. For anything mid or small cap that constraint can bind before conviction does.
   6. Then be ready to defend it under pressure, because the standard follow-up is 'are you sure the thesis can be backed up?'. The right response is to name the two or three facts the thesis depends on, say how you verified each, and concede the one you are least sure about. Defending everything equally is what gets candidates marked down.

   Where candidates lose it

   Delivering a stock pitch and never mentioning size, funding, correlation or liquidity. This question is asked in a portfolio seat, so the construction half is the differentiator. And when they push back, do not defend every point with the same conviction; identify your weakest assumption before they do.

   Expect next

   • Are you sure that thesis can be backed up? What if costs do not fall?
   • What would you sell to fund it?
   • How long would it take you to exit?
