Mutual Fund Mastery interview preparation

Indian AMCs, distributors, registrars and the global fund houses that hire for the same skills — covering the trust structure, NAV and cut-off rules, SEBI scheme categorisation, debt risk and the Potential Risk Class matrix, passives, costs, taxation and distribution. 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; we do not invent attributions.

  1. 040An index fund charges a 0.10 percent expense ratio but lagged its index by 0.35 percent last year. Where did the other 25 basis points go?Index funds and ETFsHardtechnicalPassive and index teamsIndian AMCs

    Say this

    Costs that sit outside the expense ratio. In order of likely size: cash drag from flows, transaction costs and securities transaction tax on rebalancing, dividend timing, and the fact that the index is a theoretical portfolio with no settlement cycle and no taxes.

    Then walk it

    1. Cash drag first. Money arriving through the day cannot be invested until it is available, and a fund holding even half a percent in cash in a year the index rose 15 percent gives up around 7 basis points.
    2. Rebalancing costs. When the index changes constituents the fund must trade, paying brokerage, securities transaction tax and market impact. Impact is the expensive part, because every index fund is trading the same name on the same day at the same close.
    3. Dividend treatment. A total return index assumes dividends are reinvested instantly on the ex-date. A real fund receives the cash days later and may pay tax on it, so it is out of the market in between.
    4. Then the small ones: creation and redemption frictions, corporate action handling, and any sampling if the fund does not fully replicate.
    5. A useful sanity number: for a large cap Indian index fund, a well-run product lands around 15 to 30 basis points of tracking difference on a 10 basis point TER. If it is more like 60 to 80, the cause is usually persistent cash drag or a small AUM that makes rebalancing expensive per unit.
    6. And the diagnostic question I would ask the AMC: is the gap stable year on year or lumpy? Stable means structural cost, which you can price in. Lumpy means operational quality, and that is the reason to avoid the fund.

    Where candidates lose it

    Answering 'the expense ratio' when the question has already told you the expense ratio. The interviewer wants the costs outside TER. Missing cash drag is the specific failure — it is usually the biggest single component and the one nobody names.

    Expect next

    • How would you reduce cash drag?
    • Why is index rebalancing expensive for everybody at once?
    • What tracking difference would you accept before switching funds?

Firm tags come from public, anonymous candidate reports on Wall Street Oasis: strong signal, not sworn testimony. Firms are named as the places a question was reported, not as partners of Fin Maverick. Answers are written for this page to show how to think out loud; they are not scripts to recite.
