1. 045How would you assess a fund's performance?Performance measurementIntermediatetechnicalNeuberger BermanPrivate Equity · London · 2022

   Say this

   Against the right benchmark, net of everything, decomposed into exposures, and over a period long enough to mean something. Then check that the returns came from the process the manager claims, because that is the only part that tells you anything about the future.

   Then walk it

   1. First the mechanics: net of all fees and costs, time-weighted for a fund and money-weighted only if I am measuring my own experience of it, and against a benchmark matched to the opportunity set rather than a convenient one.
   2. Then decompose. Split excess return into market beta, factor exposures and residual. If a 4 percent excess return is 3 points of small cap and value tilt, I am buying cheap beta at active prices.
   3. Then look at risk-adjusted, not absolute: information ratio against the benchmark, maximum drawdown, and the worst rolling twelve months. And look at the shape of the return series, because a fund that made everything in two quarters is a different proposition from one that grinds.
   4. Then consistency with the stated process. Hit rate, average winner versus average loser, turnover, and whether attribution matches the story. A manager who claims bottom-up picking while the returns come from sector allocation has a process-outcome mismatch, which is the most useful red flag there is.
   5. Then the statistics honesty: five years of monthly returns cannot distinguish skill from luck at any sensible confidence level, so I would weight process, team stability and capacity at least as heavily as the numbers.
   6. For private funds the measures change: IRR is money-weighted and flattered by subscription lines and early exits, so I would look at TVPI and DPI, compare against a public market equivalent, and check the vintage-year cohort rather than the absolute number. Unrealised marks in a young fund are the manager's own opinion.

   Where candidates lose it

   Going straight to returns and Sharpe ratios. The two things that earn this question are decomposing the excess return into replicable factor exposures, and admitting the sample is too short to prove skill. Since the seat here touches private markets, say why IRR is flattered and that DPI and public market equivalent are the honest comparisons.

2. 053You inherit a portfolio with thirty positions and you suspect they express the same underlying bet. How do you find out?Risk managementIntermediatecase studyRisk managementMulti-asset

   Say this

   Decompose the portfolio rather than reading the position list. Run it through a factor model, look at the risk contributions instead of the weights, and do a principal component analysis of the holdings' returns. If one component explains most of the variance, you have one position in thirty wrappers.

   Then walk it

   1. Step one, risk contribution not capital weight. Marginal contribution to risk will often show that four names out of thirty account for 60 percent of the risk, which is the first thing the weights hide.
   2. Step two, factor decomposition. Run active exposures against a standard model: market, size, value, momentum, quality, plus rates, credit spread, dollar and oil. Thirty stocks that are really one duration bet will show it immediately as a single dominant factor exposure.
   3. Step three, principal components on the return series. If PC1 explains 70 percent of the portfolio's variance and loads on everything with the same sign, the diversification is cosmetic. Then interpret what PC1 is by correlating it with observable macro series.
   4. Step four, stress and scenario. Apply specific shocks: 100 basis points on real yields, 20 percent oil, a 10 percent dollar move, a credit spread doubling. A portfolio whose entire loss in every scenario comes from the same channel has one bet.
   5. Step five, the qualitative overlay the models miss. Shared supply chain, shared customer, shared regulator, shared funding source. In 2023 a portfolio of regional bank stocks looked diversified across thirty names and was actually one bet on deposit behaviour and held-to-maturity marks.
   6. Then the action: cut the aggregate exposure rather than trimming every name a little, or hedge the common factor with a liquid instrument and keep the idiosyncratic residual, which is presumably what the manager is actually paid for.

   Where candidates lose it

   Answering 'look at the correlation matrix'. A pairwise matrix on thirty names is 435 numbers and will not tell you what the common bet is. The expected answer names risk contribution, a factor decomposition, and principal components, and it finishes with an action, hedge the common factor and keep the residual.

   Expect next

   • How would you interpret the first principal component?
   • Would you cut positions or hedge the factor?
   • What common exposures would a factor model miss?
3. 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.

   • 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?

4. 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.

   • 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?
5. 079How would you build a portfolio for an Indian high net worth client across equity, debt, gold and real estate?India marketsIntermediatecase studyIndian wealth managementIndian asset management

   Say this

   Start by netting off what they already own, because Indian HNI balance sheets are usually dominated by their business and by property, so the liquid portfolio's job is to diversify away from those, not to duplicate them. Then build the financial portfolio around goals, tax wrappers and liquidity.

   Then walk it

   1. First the existing exposure. A typical client has a concentrated business stake, two or three properties and a large insurance-linked savings product. Adding Indian mid caps to that is adding the same domestic cyclical risk. So the honest starting advice is often diversification out of India and out of illiquid assets.
   2. Then the liquid core: broad Indian equity through index funds and a small number of flexi cap managers, with a real allocation to global equity, which most Indian portfolios lack entirely. The LRS route allows 250,000 dollars per person per year, and international funds are the alternative where that is impractical.
   3. Debt sleeve sized for the goals plus two years of spending. At current yields, a mix of government securities and high-grade corporate bonds plus target maturity funds gives a predictable return, and the tax change that removed indexation on debt funds means holding period and structure now matter more than they used to.
   4. Gold, 5 to 10 percent, as rupee and crisis insurance. It has a genuine role for an Indian investor because a global risk-off event usually weakens the rupee, so gold in rupee terms does two jobs at once. Sovereign gold bonds were the efficient instrument while available; ETFs otherwise.
   5. Real estate: treat what they already own as the allocation and resist adding more. It is illiquid, lumpy, hard to value, tax inefficient on exit and highly correlated with their local economy. If they want more property exposure, REITs and InvITs give it with liquidity and transparency.
   6. Then structure and governance: use the tax wrappers correctly, consider whether PMS or AIF is justified after fees and tax, plan succession because Indian family wealth is very often held informally, and write down a rebalancing rule. And keep two to three years of expenses liquid, because the biggest destroyer of an HNI plan is having to sell a business stake or a property in a hurry.

   Where candidates lose it

   Producing a generic 60/30/10 split without looking at the concentrated business and property exposure that dominates most Indian HNI wealth. The single best answer here starts with the total balance sheet. Also, recommending more real estate to a client already heavy in property shows you are selling products rather than managing risk.

   Expect next

   • How much international exposure and how would you get it?
   • Would you use a PMS for this client?
   • How do you handle a concentrated stake in their own unlisted business?
6. 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?
