1. 070What is the difference between a mutual fund distributor, a registered investment adviser and an execution-only platform, and who can charge what?Distribution, compliance and NISMIntermediatetechnicalDistribution and salesCompliance and legal

   Say this

   A distributor is paid by the AMC through trail commission and sells regular plans. An RIA is paid by the client, must act in the client's interest and recommends direct plans. An execution-only platform does neither — it takes orders without advice. Crucially, the same entity cannot both advise for a fee and earn commission from the same client.

   Then walk it

   1. Distributor: AMFI-registered with an ARN, NISM V-A certified, cannot charge the client a fee, earns trail from the scheme. The legal standard is suitability and the AMFI code of conduct, not fiduciary duty.
   2. RIA: SEBI-registered, higher qualification and net worth bar, fee-only, with a cap on the fee expressed either as a percentage of assets or as a fixed amount per family per year. Must maintain risk profiling records and a documented rationale for every recommendation.
   3. SEBI's separation rule is the point of the whole framework: advice and distribution must be at arm's length, with client-level segregation. An individual cannot advise you for a fee and also collect commission on what you buy.
   4. Execution-only platforms sit in a third bucket, and SEBI created a specific registration route for them so that direct-plan platforms could operate legitimately without pretending to give advice. They may charge a flat platform fee.
   5. In practice most Indian investors deal with a distributor, because the RIA population is tiny — a few thousand registrations for a market of crores of investors. The fee-only model has not scaled here, largely because clients resist a visible fee while accepting an invisible one.
   6. What I would say if asked which model is better: the RIA structure removes the conflict but has not solved distribution economics. The honest position is that a good distributor beats a bad adviser, and the framework matters less than whether the person can articulate why they recommended what they recommended.

   Where candidates lose it

   Saying the distributor is 'not allowed to give advice'. Distributors give incidental advice constantly; the rule is that they cannot charge a fee for it and are held to suitability rather than fiduciary duty. Getting that distinction wrong in a compliance interview is costly.

   Expect next

   • Can one firm run both a distribution and an advisory arm?
   • Why has the RIA model not scaled in India?
   • What is the fee cap for an RIA?
2. 071Why ratings? How do fund ratings actually work, and what's wrong with a five-star rating?Distribution, compliance and NISMIntermediatefirst roundMorningstarOther · Chicago · 2025

   Say this

   Star ratings are almost entirely a backward-looking, risk-adjusted ranking of past returns within a category, usually on a bell curve where the top 10 percent get five stars. They tell you what happened, not what will happen, and the evidence that they predict future performance is weak.

   Then walk it

   1. How they are built: take the category peer group, compute risk-adjusted returns over three, five and ten years, weight and combine them, then rank and assign stars by percentile. Ratings only exist once a fund has enough history, which excludes exactly the funds you most need judgement about.
   2. The mechanical consequences: the rating is relative to a category, so a five-star fund in a weak category can be worse than a three-star fund in a strong one. And the rating changes when peers change, not only when the fund does.
   3. Why it misleads: a fund that took a big sector bet that paid off scores highly on risk-adjusted returns computed on a period where that bet worked. The rating rewards the outcome and cannot see the process.
   4. There is also a reversion problem. The published research on this — including from rating agencies themselves — shows that low-cost funds predict future relative performance better than high star ratings do. Cost is the more reliable signal.
   5. Which is why the serious houses moved to a second, forward-looking layer: analyst-driven assessments of people, process, parent, performance and price. That is qualitative judgement, published with a rationale, and it is a different product from the star count.
   6. So how I would use ratings: as a screen to build a shortlist and as a way to notice a fund's peer ranking changing, then do the real work — process, attribution, rolling returns, cost, manager tenure and capacity. A rating is the start of the diligence, not a substitute for it.

   Where candidates lose it

   Treating a star rating as a recommendation. Interviewers at a ratings or research house are testing whether you understand the difference between a quantitative backward-looking rating and a forward-looking analyst view. If you cannot name that distinction, you have not understood the business you are applying to.

   Expect next

   • What predicts future relative performance better than a star rating?
   • How would you build a forward-looking rating?
   • How does a rating change when the category peer group changes?

3. 072Tell me about a time you saw someone do something morally wrong, and what you did about it.Distribution, compliance and NISMIntermediatesuperdayJ.P. MorganAsset Management · New York · 2026

   Say this

   Pick something real, small and resolved, where you raised it with the person first and then escalated only if you had to. The competency being tested is whether you act and whether you act proportionately — not whether you have witnessed fraud.

   Then walk it

   1. Choose the right scale. A friend copying an assignment, a colleague inflating hours on a timesheet, a team member misrepresenting a number in a client deck. Something ordinary that you actually handled beats a dramatic story you were peripheral to.
   2. Structure it tightly: what you observed, why it crossed a line, what you did first, what happened, and what you would do differently. Sixty to ninety seconds.
   3. The step interviewers listen for is the direct conversation. 'I spoke to him privately and said this number cannot go to the client' shows judgement. Going straight to escalation reads as risk-averse; saying nothing and rationalising it fails the question.
   4. Then name the reasoning, because that is what transfers to the job. 'It was a number going to a client, so it was not mine to let slide' is a principle an interviewer can imagine you applying in a fund house.
   5. Connect it to this industry explicitly. In asset management the everyday version is not fraud — it is a fund sold to someone it does not suit, a risk not disclosed, an NFO pushed because of a sales target. If you have seen a version of that, it is the ideal answer.
   6. And do not moralise. State what you did, concede it was awkward, and stop. Candidates lose this question by performing integrity rather than describing an action.

   Where candidates lose it

   Two failure modes. Choosing an example so small it reveals no judgement, or one so serious that the obvious follow-up — did you report it, and what happened — exposes that you did nothing. Pick something you actually resolved, and say what the resolution was.

   Expect next

   • What if it had been your manager doing it?
   • Have you ever stayed silent when you should have spoken up?
   • What would you do if you were told to sell a product you thought was unsuitable?

4. 073How would you build a portfolio for a range of clients with very different needs and requirements?Portfolio construction and adviceIntermediatecase studyVanguardInvestment Research · Malvern · 2024

   Say this

   Start from the liability, not the product. For every client I need three things: when the money is needed, how much volatility they can actually tolerate as opposed to claim to tolerate, and what tax bracket and constraints they face. The asset allocation falls out of those, and fund selection is the last and least important step.

   Then walk it

   1. Horizon sets the equity share. Money needed inside three years does not belong in equity at all, whatever the client's risk appetite, because the worst three-year outcome is too bad. Beyond ten years, equity is the low-risk choice against inflation.
   2. Then capacity versus tolerance. Capacity is arithmetic — income stability, dependants, existing assets. Tolerance is behavioural. Where they conflict, size to tolerance, because a client who redeems in a drawdown converts a paper loss into a permanent one.
   3. Then build with as few products as possible. A large cap index fund, one flexi cap or mid cap, one short duration debt fund, and a liquid fund for near-term needs covers the large majority of clients. Complexity is the enemy of adherence.
   4. Differentiate at the edges, not the core. A 30-year-old with a stable salary and a 25-year horizon gets 75 to 85 percent equity with an SIP. A 60-year-old drawing income gets a bucketed structure with an SWP from the debt sleeve. A business owner with lumpy income gets a bigger liquid buffer.
   5. Then tax and jurisdiction. An Indian investor in the 30 percent bracket routes short-horizon money through arbitrage rather than debt funds. A US-taxable client cannot hold Indian mutual funds efficiently at all, and that constraint overrides every allocation view.
   6. And write down the rebalancing rule and the review date at the start. Most portfolios fail from drift and from ad hoc changes, not from bad initial selection — which is why I would rather have an average fund list with a written policy than a brilliant fund list without one.

   Where candidates lose it

   Answering with a fund list. The interviewer is testing whether you start from the client's liabilities and constraints. Also, distinguishing risk capacity from risk tolerance, and saying you would size to the lower of the two, is the line that separates an adviser from a salesperson.

   Expect next

   • What if the client's stated tolerance is much higher than their capacity?
   • How many funds should a portfolio hold?
   • How would you handle a client with a large concentrated stock position?

5. 074How would you invest 10 million pounds?Portfolio construction and adviceIntermediatesuperdaySCSchrodersAsset Management · London · 2023

   Say this

   My first move is to ask whose money it is and what it is for, because the answer is completely different for an endowment, a pension scheme and a private individual. If you want me to pick, I will assume a taxable individual with no immediate liability and a twenty-year horizon, and I will say so before I allocate a pound.

   Then walk it

   1. State the assumptions out loud: horizon, liquidity needs, tax status, base currency, existing wealth, and whether there is a spending requirement. Making them explicit is the whole test, because the interviewer wants to see if you build from a mandate.
   2. Then a defensible allocation, roughly: 55 to 60 percent global equity, mostly indexed given the size and the cost saving available; 20 percent fixed income split between government bonds and investment grade credit; 10 percent real assets, listed infrastructure and property; 5 to 10 percent in cash and near-cash for two to three years of spending.
   3. Justify the shape, not the numbers. The equity weight comes from the horizon, the bond weight is there to fund spending in a drawdown, and the real assets are for inflation exposure the bonds cannot provide.
   4. Then implementation, which is where the size actually matters. At 10 million you get institutional share classes, so total cost can come in under 20 basis points on the passive core. Fee negotiation on that scale is worth more than most manager selection decisions.
   5. Then risks and what would change my mind: currency exposure and whether to hedge the non-sterling bonds, concentration in US mega-caps in any global index today, and sequence risk if there is a spending requirement in the first five years.
   6. And a deployment plan rather than a single date. Half now, the rest over three to six months, with a written rule so it happens regardless of how markets look at the time.

   Where candidates lose it

   Allocating immediately without asking what the money is for. The question is deliberately underspecified. But do not hide behind questions either — ask two or three, state your assumptions, and then commit to an actual allocation with reasons. Refusing to give numbers reads as evasion.

   Expect next

   • Now it is a pension scheme with liabilities in fifteen years. What changes?
   • Would you hedge the currency?
   • Active or passive, and why?

6. 075Talk me through diversification. How many mutual funds does a portfolio actually need?Portfolio construction and adviceIntermediatetechnicalNorthern TrustAsset Management · Chicago · 2025

   Say this

   Four to six for almost anyone. Diversification comes from owning uncorrelated assets, not from owning many funds, and beyond about four equity funds you are adding overlap and cost, not risk reduction. Most Indian retail portfolios hold twelve schemes that together are one large cap fund with a higher expense ratio.

   Then walk it

   1. The principle: risk falls when you add assets whose returns do not move together. Two large cap funds in the same market have a correlation near 0.95 and an enormous overlap of holdings, so the second one reduces almost nothing.
   2. Test it directly. Pull the top 20 holdings of the funds a client owns and compute the overlap. It is routine to find 60 to 70 percent common holdings across four supposedly different equity schemes, and showing a client that table is the most persuasive thing you can do.
   3. What actually diversifies an Indian portfolio: moving down the market cap curve, adding debt with a different driver, adding gold, and adding international equity, because domestic and global equity cycles genuinely differ.
   4. So the shape I would use: one core equity fund or index fund, one mid or small cap, one debt fund matched to the horizon, one liquid fund, plus optionally gold and an international sleeve. That is five or six line items and it covers everything.
   5. The costs of over-diversification are real and under-discussed: you dilute any manager skill you were paying for, you make rebalancing a multi-scheme tax event, and you make the portfolio impossible to monitor, so it never gets reviewed.
   6. One honest caveat: for a very large portfolio there is a case for splitting across AMCs to limit single-manager and single-house operational risk. That argument justifies maybe two managers per sleeve, not twelve.

   Where candidates lose it

   Equating number of funds with diversification. The answer that lands names portfolio overlap as the measurable test and points out that the second large cap fund adds cost, not diversification. Mentioning that rebalancing across many schemes is a taxable event in India shows you have advised real clients.

   Expect next

   • How would you measure overlap between two funds?
   • Does holding funds from different AMCs help?
   • Where does gold fit, and how much?

7. 076Go over the valuation methods you would use on a stock you were considering for the fund.Portfolio construction and adviceIntermediatetechnicalInvescoAsset Management · New York · 2023

   Say this

   Three families: intrinsic, relative and asset-based. A discounted cash flow for what the business is worth on its own cash generation, trading comparables and precedent transactions for what the market is paying for similar businesses, and net asset or sum-of-the-parts where the assets are the story. I would triangulate rather than pick one.

   Then walk it

   1. DCF: project free cash flow, discount at the weighted average cost of capital, add a terminal value. It is the only method that is theoretically right and the one most sensitive to assumptions — typically 60 to 75 percent of the value sits in the terminal value, which is why I run it as a range.
   2. Trading comparables: EV to EBITDA, price to earnings, EV to sales for pre-profit businesses, price to book for financials. Fast, market-based, and circular — if the whole sector is mispriced, comps tell you nothing.
   3. Precedent transactions: what acquirers paid, which embeds a control premium and so sits above trading multiples. Useful for a floor in a takeover situation, weak for a minority stake.
   4. Special cases matter in India. Banks and NBFCs go on price to book against return on equity, because cash flow is not meaningful for a lender. Conglomerates and holding companies need a sum of the parts with an explicit holding-company discount, which in India has run at 30 to 60 percent.
   5. Then the reverse DCF, which is the technique I would actually lead with in a fund context: take today's price and solve for the growth and margin the market is assuming. It turns valuation from a forecast into a question about whether the embedded expectation is plausible.
   6. And the discipline: a valuation is a range with a stated set of assumptions, not a target price. If the answer changes from 900 to 1,400 on a one percent change in terminal growth, the honest output is that the stock is not valuable enough to own.

   Where candidates lose it

   Listing DCF, comps and precedents mechanically without saying which you would weight and why. In an asset management seat, mentioning the reverse DCF and the price-to-book treatment for financials is what shows you have valued something rather than read about valuing something.

   Expect next

   • Which method would you weight most for an Indian private bank?
   • How do you handle the terminal value?
   • What is a reverse DCF and why would you use it?

8. 078If margin goes down by 5 percent, how much would revenue need to increase to balance it out?Estimation and numeracyIntermediatetechnicalSycamore PartnersConsumer and Retail · New York · 2026

   Say this

   Clarify the question first, because there are two readings. If margin falls 5 percent relatively — from 20 percent to 19 — revenue must rise about 5.3 percent to hold profit flat. If it falls 5 percentage points, from 20 to 15, revenue has to rise by a third.

   Then walk it

   1. The algebra is one line. Profit equals revenue times margin. To keep the product constant, the revenue multiplier is the old margin divided by the new margin.
   2. Relative case: 20 percent falls to 19 percent. 20 divided by 19 is 1.053, so revenue rises 5.3 percent. Note it is slightly more than 5 percent, because the reciprocal is not symmetric — saying that unprompted is the part that impresses.
   3. Absolute case: 20 percentage points to 15. 20 over 15 is 1.333, so revenue rises 33 percent. Which reading applies changes the answer by a factor of six, so ask.
   4. Generalise it: a fall of x percent in margin needs revenue up by x over one minus x. A 10 percent relative margin hit needs 11.1 percent more revenue, a 20 percent hit needs 25 percent.
   5. Then say why it matters commercially, because that is what a consumer or retail interviewer is really after. Low-margin businesses are brutally exposed — for a retailer at 3 percent margin, losing one percentage point means revenue must rise 50 percent to stand still. That is the whole reason grocery retail lives or dies on cost discipline.
   6. And flag the assumption: this holds only if the incremental revenue carries the same margin. If the extra volume comes through discounting, it arrives at a lower margin and you need substantially more of it, which is the usual reason these plans fail.

   Where candidates lose it

   Answering 5 percent instantly because the numbers look symmetric. They are not — it is 5.3 percent, and interviewers use this to see whether you actually compute or just pattern-match. The bigger trap is not asking whether the 5 percent is relative or in percentage points.

   Expect next

   • Now do it for a business at 3 percent margin.
   • What if the incremental revenue comes at a lower margin?
   • Which would you rather fix, price or cost?

9. 079Roughly how big is the Indian mutual fund industry, and how many actual investors does it have?Estimation and numeracyIntermediatefirst roundIndian AMCsDistribution and sales

   Say this

   Industry assets are north of 70 lakh crore rupees, call it 800 to 900 billion dollars. There are roughly 25 crore folios but only about 5.5 crore unique investors by PAN, and monthly SIP inflows run somewhere around 28,000 to 30,000 crore. The gap between folios and unique investors is the number worth talking about.

   Then walk it

   1. Build it rather than recall it if you are unsure. Indian equity market capitalisation is around 450 lakh crore. Mutual funds own roughly 9 to 10 percent of listed equity, so domestic equity scheme AUM is in the 25 to 30 lakh crore range, and equity is a little under half the industry. That triangulates to 65 to 75 lakh crore total.
   2. Split it: roughly 55 to 60 percent equity-oriented including hybrids, the rest debt, liquid and passive, with passive now well over 10 lakh crore and growing faster than active.
   3. Investor reach is the real story. About 5.5 crore unique PANs against a population of 140 crore and roughly 8 crore income tax filers. Penetration is low even against the taxpaying population, let alone the country.
   4. Geography is concentrated too. The top five cities account for a large share of AUM, which is exactly why SEBI permits an extra expense allowance for inflows from beyond the top 30 cities.
   5. SIP flows are the structural change. Well over 25,000 crore a month of largely automated equity buying has made domestic institutions a counterweight to foreign flows — in 2022 foreign investors sold heavily and Indian equities held up, which would not have happened a decade earlier.
   6. Caveat the numbers explicitly. These move every month, AMFI publishes them, and the honest answer in an interview is a magnitude plus the direction plus where the data comes from, not a spuriously precise figure.

   Where candidates lose it

   Either refusing to give a number or quoting one to two decimal places. The skill being tested is whether you carry the industry's scale in your head and can triangulate it. Confusing folios with investors is the specific error — 25 crore folios sounds like mass adoption and 5.5 crore people does not.

   Expect next

   • What share of Indian equity do domestic mutual funds own?
   • How much of the industry is passive now?
   • Why is the folio count so much higher than the investor count?
10. 081A fund falls 50 percent and then rises 50 percent. Where is the investor? And why does an average annual return overstate what people actually earn?Estimation and numeracyIntermediatetechnicalIndian AMCsDistribution and sales

    Say this

    Down 25 percent. A hundred falls to fifty, then fifty plus half of fifty is seventy-five. To get back to par from minus 50 you need plus 100, and that asymmetry is why the arithmetic average of returns always overstates the compounded result.

    Then walk it

    1. The general rule: the recovery needed is the loss divided by one minus the loss. Down 20 needs plus 25. Down 33 needs plus 50. Down 50 needs plus 100. Down 80 needs plus 400, which is why a wipeout in a concentrated position is effectively permanent.
    2. In this example the arithmetic average of minus 50 and plus 50 is zero, while the geometric average, the compound annual return, is minus 13.4 percent a year over two years. The gap between the two is driven by volatility.
    3. The approximation worth knowing: geometric return is roughly the arithmetic return minus half the variance. So two funds with the same average return and different volatility do not deliver the same wealth, and the more volatile one delivers less.
    4. That is the mathematical case for caring about drawdown rather than just average return, and it is why a small cap fund with a higher average can compound to less than a steadier fund over a full cycle.
    5. There is a second, separate gap: investor return against fund return. Money arrives after good years and leaves after bad ones, so the money-weighted XIRR investors actually earn is typically 1 to 3 percentage points below the fund's reported CAGR. Naming both gaps is the complete answer.
    6. So what I would say to a client: your return is not the average of the annual numbers on the fact sheet, and the single biggest thing you control is not selling at the bottom.

    Where candidates lose it

    Saying the investor is back to break-even. It is the classic reflex error. Then, if you only do the arithmetic and never name the geometric-versus-arithmetic point or the investor-return gap, you have answered a puzzle rather than a fund question.

    Expect next

    • What return does a fund need after a 30 percent drawdown?
    • Why is the investor's return usually lower than the fund's?
    • How does volatility reduce compounded wealth?
