Portfolio Management interview preparation
Asset allocation, factor models, risk, attribution and implementation, on global and Indian portfolios. Every question is either traced to a named firm from a public candidate report, or tagged at desk level when we could not trace it, and answers lead with the point, then the mechanism, then the limitation.

015A new institutional client hands you a mandate. How do you set the strategic asset allocation?VanguardInvestment 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
- 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.
- 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.
- 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.
- 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.
- 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.
- 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?

018How would you invest ten million pounds?SchrodersAsset 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
- 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.
- 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.
- 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.
- 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.
- 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.
- 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?

023Would you allocate to retail real estate today, and why?NuveenInvestment 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
- 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.
- 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.
- 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.
- 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.
- 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.
- 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?

024Which sector would you overweight today, and what would you fund it from?Wellington ManagementGeneralist · Hong Kong · 2022
Say this
The 'funded from' half is the real question. A sector view is only a portfolio decision once you have said what it displaces, and the pair determines what risk you have actually taken, because an overweight funded from cash is a beta increase and one funded from a correlated sector is a relative value trade.
Then walk it
- Pick a sector where you can state the mechanism in one sentence, name the two or three numbers, and say what the market is assuming that you think is wrong. Specificity beats breadth here.
- Then be explicit about the funding leg. Funding an overweight from cash adds market beta. Funding it from a defensive sector adds beta and cyclicality. Funding it from a sector with the same driver, say industrials out of materials, isolates the idiosyncratic view, which is usually what you intend.
- Check what else comes with it. Sector bets carry factor exposures whether you want them or not: financials are a rate and curve bet, staples are duration, technology is long growth and long the multiple. Say which factor you are unintentionally buying.
- Size it against a tracking error budget. A 3 point sector overweight in a portfolio with a 3 percent tracking error budget is a substantial use of that budget, and I would say how much of the budget I am spending.
- Give the falsifier and horizon: the data point that would tell me I am wrong, and when I would review. Sector rotations often need two to three quarters to work, so a one month judgement is noise.
- And I would be honest that sector allocation has a weaker evidence base than stock selection within sectors, so I would keep the tilt modest unless the mispricing is unusually clear.
Where candidates lose it
Giving a sector view and never saying what you sell. Interviewers in allocation seats are specifically listening for the funding leg and for the factor exposure that comes attached. Naming the unintended factor bet, rates in financials or duration in staples, is what makes it sound like a real portfolio decision.
Expect next
- What factor exposure does that pair give you?
- How much of your tracking error budget does it use?
- What would make you close it?

027It is March 2020 and your equity weight has fallen twelve points below target. Do you rebalance?Multi-assetInstitutional asset management
Say this
Yes, because the policy says so, but in stages and with a liquidity check first. The whole value of having a written rebalancing rule is that it is executed in exactly this moment, when doing it feels worst.
Then walk it
- First, the liquidity check. Can I raise cash for the equity purchase without selling the only liquid thing I own? In March 2020 investment grade bid-ask spreads widened enormously, so funding the trade by selling credit would have crystallised a big cost.
- So fund it in order of cheapest execution: cash buffer first, then equity futures to restore beta immediately, then rotate into physicals over days as spreads normalise. Futures are the right instrument precisely because cash equity impact is at its worst.
- Stage it. Move a third of the gap at a time against defined triggers rather than one block, which both reduces impact and is easier to defend to a committee if it falls another 10 percent.
- Check whether the target itself is still right. Rebalancing is not the same decision as revisiting the strategic allocation. If the client's circumstances changed, for example a pension sponsor whose covenant just deteriorated, then a lower equity target is legitimate. Otherwise drift is not information.
- Say the governance point: the reason committees fail this test is that rebalancing requires buying while the newspapers say the world is ending, so the rule has to be pre-agreed and the execution delegated. A rule that needs a fresh vote in a crisis is not a rule.
- The honest counterweight: if the drawdown has pushed the institution near a hard constraint, a regulatory capital floor or a funding trigger, then mechanically rebalancing into risk can be the wrong answer. Constraints override policy, and saying that shows you are not just reciting discipline.
Where candidates lose it
Answering 'yes, rebalance' with no mention of liquidity or execution. In a real crisis the constraint is not conviction, it is that the cheap side of the trade is illiquid. The strong answer names futures for the fast beta restoration and staged physical trading, and flags the one case where you would not rebalance, a hard constraint being near breach.
Expect next
- How would you fund the purchase?
- What would make you not rebalance?
- How do you stop the committee overriding the rule?
045How would you assess a fund's performance?Neuberger 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
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
Expect next
- How is assessing a private fund different?
- How long a record would you want?
- What would make you redeem?

053You inherit a portfolio with thirty positions and you suspect they express the same underlying bet. How do you find out?Risk 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
- 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.
- 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.
- 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.
- 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.
- 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.
- 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?
079How would you build a portfolio for an Indian high net worth client across equity, debt, gold and real estate?Indian 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
- 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.
- 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.
- 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.
- 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.
- 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.
- 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?
