Pooled Investments

How mutual funds, ETFs, SIFs, AIFs, REITs and InvITs work, with NAV, IDCW, costs, SIPs, STP and SWP, and the SEBI Riskometer.

A mutual fund, an ETF, a REIT and an AIF are all ways of holding a portfolio you do not assemble yourself. Four things separate them, and all four are in the documents rather than in the name: what the mandate permits, who is allowed to invest, how you get your money out, and what the structure costs you.

This lesson is about those mechanics. It is written so that you can read a scheme document, not so that you can pick a scheme.

What a mutual fund is, and how NAV works

A mutual fund collects money from investors and issues units. Each investor owns units of the fund, not the underlying shares directly. The fund is managed according to a stated mandate.

Net asset value (NAV) is the value of the fund’s assets minus its liabilities, divided by the number of units outstanding. For open-ended mutual funds, NAV is calculated at the end of each business day.

The NAV you get is not necessarily today’s NAV. Unlike a share, an ordinary open-ended fund is not continuously quoted. The applicable NAV depends on the cut-off time for the transaction and, for a purchase, on when the subscription money becomes available to the fund. Placing an order before the cut-off generally gets that day’s NAV; placing it later generally gets the next business day’s NAV. Liquid and overnight funds have their own cut-off and realisation rules. Read the scheme’s cut-off disclosure before assuming a date.

The mandate matters more than the name. SEBI’s categorisation framework imposes requirements on what a scheme in a given category may hold, so the label is not meaningless. But the actual portfolio, the residual flexibility allowed by the scheme, and the disclosures are what tell you what you own. Read the scheme information document and the monthly portfolio.

Types of mutual funds in India

SEBI standardises mutual-fund categories so that schemes within a category follow prescribed characteristics. A category label communicates important investment constraints, but it does not fully describe the actual portfolio or its risk. The categories below follow the framework in force from February 2026, which groups schemes into five broad families: equity, debt, hybrid, life-cycle and other. Solution-oriented schemes (retirement and children’s) were discontinued under this framework.

Use the five cards below to explore the families. Each card introduces the family and its major subtypes.

The five families above come from the SEBI circular dated 26 February 2026. The details of every subtype are a regulatory question, and the category a scheme is sold under does not on its own tell you what it holds. Sources: SEBI Categorization and Rationalization of Mutual Fund Schemes (26 Feb 2026), the SEBI (Mutual Funds) Regulations, 2026, and AMFI’s scheme categorisation.

Active versus passive

Active funds employ a manager who selects securities, aiming to beat a benchmark. Active funds often carry higher expenses, but the expense ratio has to be checked scheme by scheme rather than inferred from the label. Whether the outperformance covers the fee is an empirical question. The evidence in most developed markets is that most active funds underperform their benchmark net of costs over long periods. India is a large and less efficient market, so the result is less one-sided, but the fee still has to be earned.

Passive funds track an index. An index fund holds the constituents in the index weights and aims to match the index return, before costs. Because there is little research and less trading, the expense ratio is usually lower. The result is the index return minus costs: you are not trying to beat the market, you are trying to own it cheaply.

Index funds versus ETFs

Index funds are bought and redeemed from the fund house at the applicable NAV. They are not traded during the day, a demat account is not generally required, and a SIP is usually supported.

Exchange-traded funds (ETFs) are, in India, generally passive funds designed to track a specified index or benchmark. Their units trade on a stock exchange at market-determined prices during trading hours. That introduces two things an ordinary index fund does not have:

• Price versus NAV. An ETF’s market price can trade slightly above (premium) or below (discount) its NAV. For large, liquid ETFs the gap is usually small; for thin ones it can be meaningful.
• Liquidity and spread. A large ETF with many buyers and sellers is easy to trade. A small one may have a wide bid-ask spread, so entry and exit cost more than the expense ratio suggests.

An ETF is not only an investor-to-investor market. Authorised participants and market makers can create or redeem units in creation-unit sizes through the applicable mechanism, which is part of how the market price stays close to NAV. An ordinary investor usually buys and sells on the exchange.

Tracking difference and tracking error

Two measures help assess a passive fund, and they are not the same.

Tracking difference is the gap between the fund’s return and the benchmark’s return over a period. A fund that returns 12.1% when its benchmark returns 12.5% has a tracking difference of minus 0.4 percentage points, before any adjustment for the benchmark version.

Tracking error measures how consistently the fund follows the benchmark, usually as the standard deviation of the periodic return differences. A fund can have low tracking error and a persistent negative tracking difference, because expenses, cash balances, rebalancing and other recurring drag pull the return below the index every period.

Low tracking error does not mean low tracking difference. Both matter, and both depend on which benchmark is used. A total-return index (which assumes dividends are reinvested) and a price-return index (which does not) are not interchangeable, and a comparison that mixes them is not a like-for-like comparison.

Mutual fund versus ETF, side by side

Growth versus IDCW

A mutual fund scheme may offer different distribution options. The two a beginner meets are Growth and Income Distribution cum Capital Withdrawal (IDCW).

• Growth: returns remain reflected in the unit’s NAV. The NAV rises as the portfolio gains, and no distribution is paid out.
• IDCW: the scheme distributes an amount to unit holders. The distribution reduces the NAV by the distributed amount, subject to applicable adjustments.

IDCW is not extra return and it is not free income. It is a withdrawal from the scheme’s assets, and the NAV falls by the amount distributed. If the NAV is ₹20 and the scheme distributes ₹3, the NAV becomes approximately ₹17, ignoring other market movements and charges. The investor has ₹3 in cash and units worth about ₹17, not ₹20 of units plus ₹3.

An IDCW distribution is not guaranteed. It depends on the scheme, the distributable surplus and the trustee’s decision.

Costs

Costs compound against you, and they are one of the few things about a fund that can be known in advance. Under the SEBI (Mutual Funds) Regulations, 2026, effective 1 April 2026, the total expense ratio is made up of distinct parts rather than one unqualified number:

• Base expense ratio (BER): investment management and advisory fees and recurring scheme expenses, within the limits set by the regulations.
• Brokerage cost: charged within the applicable limits.
• Transaction cost: the cost of executing trades, over and above the base expense ratio.
• Statutory levies: GST and other applicable levies, over and above the base expense ratio.

The practical point is not to memorise the limits. It is that a single quoted “expense ratio” may not capture every cost, and the scheme’s disclosure is the place to check what is included.

• Direct versus regular plans: a regular plan pays a commission to a distributor, which is included in its expenses. A direct plan bought from the fund house or a platform has lower expenses and the same portfolio. Over a long holding period the difference is material.
• Exit load: a fee for redeeming within a stated period, often one year for equity funds. Read it before you buy, not when you sell.
• Brokerage and spread: for ETFs, the cost of trading, which can exceed the expense ratio for a small purchase.
• Taxes: the treatment depends on the fund’s equity exposure and your holding period, and the rates change. Our taxation lesson sets out the framework; check the current rules before you sell.

Cost is an important, observable determinant of net returns, especially when comparing otherwise similar passive funds. It is not a universal predictor of relative performance across funds with different mandates.

Mutual Fund Risks and the SEBI Riskometer

Every fund carries risk, and the type depends on the mandate.

• Market risk: equity prices can fall, and a diversified equity fund still falls with the market.
• Credit risk: a debt fund’s issuer may fail to pay.
• Interest-rate risk: bond prices fall when yields rise.
• Liquidity risk: the fund may not be able to sell holdings quickly at a fair price.
• Concentration risk: sectoral and thematic funds can be far less diversified than their category suggests.

The SEBI Riskometer is a standardised indicator printed on scheme documents. It grades a scheme from Low through Low to Moderate, Moderate, Moderately High, High and Very High. It is a relative risk indicator for the scheme, not a capital guarantee and not a prediction. A “Low” risk grade does not mean the investment cannot lose money.

Diversification reduces concentration risk, not market risk. A portfolio of ten equity funds is still exposed to the equity market. Diversification within equities does not remove equity-market risk.

SIPs: rupee-cost averaging and its limits

A systematic investment plan (SIP) is a standing instruction to invest a fixed amount at a fixed interval, usually monthly.

When the NAV is lower, the same instalment buys more units; when it is higher, it buys fewer. This is called rupee-cost averaging.

For equal instalments, the average purchase cost per unit is the total amount invested divided by the total units purchased. That figure is the harmonic mean of the purchase NAVs, which is no greater than their arithmetic mean. A two-instalment example shows the arithmetic:

Average cost per unit = ₹2,000 ÷ 150 = ₹13.33.

Arithmetic average NAV = (₹10 + ₹20) ÷ 2 = ₹15.

The average cost is below the arithmetic average NAV. That is the arithmetic benefit, and it is all it is. It does not guarantee a profit. If the NAV subsequently falls to ₹12, the investor still has an unrealised loss despite the average-cost benefit. Nor does it mean a SIP will outperform a lump sum invested earlier: if the market rises over the period, investing the lump sum early usually wins.

What a SIP does:

• It removes the decision of when to invest, which removes a common source of bad timing driven by emotion.
• It spreads purchases across market levels, so a single entry point matters less.
• It builds a habit, which for many people is the largest single factor in whether they invest at all.

What a SIP does not do:

• It does not guarantee a profit. A SIP into a falling market loses money for as long as the fall continues.
• It does not make an expensive fund cheap. A high-cost fund remains high-cost on every instalment.
• It does not remove the need to choose an appropriate fund and an appropriate amount.
• It does not beat a lump sum in a rising market.

A step-up SIP increases the instalment over time. Its benefit depends on the starting amount, the rate of increase and the duration, so it is not automatically more important than the starting amount.

SIP, STP and SWP

These three facilities are often confused. They are systematic transaction facilities, not asset classes or pooled investment vehicles, and not guaranteed-return strategies.

An SWP withdrawal may include a return of the investor’s own capital, not only gains. An STP is subject to the applicable redemption, exit-load and tax rules of the scheme it transfers from. Neither creates a return that the underlying portfolio did not earn.

Specialized Investment Funds (SIFs)

SEBI introduced the Specialized Investment Fund framework by circular on 27 February 2025, effective 1 April 2025. SIFs are a mutual fund product under the SEBI (Mutual Funds) Regulations, 2026, and they permit specified strategies with more flexibility than conventional mutual fund schemes.

A SIF is offered by an asset management company through the mutual fund framework, not through private placement. Not every AMC offers one, and the scheme documents set out the strategy and its limits.

Minimum investment. The general requirement is an aggregate investment of at least ₹10 lakh at the investor’s PAN level across all investment strategies offered by a SIF. It is not ₹10 lakh per strategy, and it does not include the investor’s regular mutual fund schemes of the same AMC. Accredited investors are exempt from the threshold, and mandatory investments by an AMC for designated employees are outside it. The AMC monitors the threshold; the requirement is that the investor’s own transactions (redemption, transfer, sale) do not take the total below ₹10 lakh. A market decline that reduces the value is a different matter from an active breach.

Strategies. The framework permits strategy families such as equity long-short, debt and hybrid, with derivative exposure within the limits set for the strategy. It does not permit unrestricted short-selling or unrestricted leverage. The exact strategy categories and limits are in the circular and the scheme documents.

Liquidity. A SIF may be open-ended, close-ended or interval, as disclosed. Not every SIF offers daily redemption. Read the redemption window and any lock-in before investing.

Risks. A SIF carries the risks of its strategy: directional exposure, short or derivative exposure, market volatility, exposure amplification where permitted, liquidity restrictions, strategy complexity, manager execution, fees and transaction costs. Hedging does not remove the possibility of loss. A long-short strategy is not necessarily market-neutral, and a market-neutral strategy can still lose money.

SIF versus an ordinary equity fund. A conventional equity mutual fund is generally long-only. An SIF using a long-short strategy may take short exposure through derivatives within its limits, so its return pattern and risk are different. That is a difference in mandate and exposure, not a promise of higher returns.

Alternative Investment Funds (AIFs)

AIFs are privately pooled investment vehicles established or incorporated in India, regulated under the SEBI (Alternative Investment Funds) Regulations, 2012, as amended. They raise capital through private placement and invest according to their placement documents. They are not retail mutual fund schemes.

AIFs may invest in venture capital, private equity, private credit, infrastructure, special situations, hedge-fund-like strategies and other permitted approaches. Not every AIF is a hedge fund, and not every AIF is a private equity fund.

The three AIF categories

Category I covers funds that invest in specified sectors or activities, such as venture capital, infrastructure, SME and social impact. The broad purpose is investment in those areas under the applicable framework. Not every Category I fund carries the same government incentive; check the scheme.

Category II is the residual private-pooled category. It includes private equity, private credit, real estate and debt approaches. It is not limited to equity. Investments are often in unlisted companies, the horizon is longer, and liquidity is limited.

Category III may use diverse or complex trading strategies and, where permitted, leverage and derivatives within regulatory limits. Examples include long-short equity, relative value and quantitative strategies. Not every Category III AIF uses leverage or short-selling.

These are introductory descriptions. The precise classification and permitted activities follow the regulations.

Minimum investment

The general minimum is ₹1 crore per investor. Employees and directors of the AIF or the Manager have a lower threshold of ₹25 lakh. Accredited investors are exempt from the ₹1 crore minimum, subject to the conditions in the regulations. Other special provisions apply to particular fund types.

The minimum is a commitment, not necessarily cash paid on day one. An investor may commit ₹1 crore and the fund may call capital over time under its documents. That illustration is not a term of any particular fund.

Capital commitments and capital calls

• Commitment: the amount the investor legally agrees to provide under the fund documents.
• Capital call or drawdown: a request to contribute part of the commitment.
• Uncalled commitment: the part that may still be requested.
• Distribution: capital or proceeds returned under the fund terms.

An investor may remain obligated to fund future calls even when the investment is not performing well. Fund performance and distributions received are different measures. Not every AIF uses capital calls.

Open-ended and close-ended

Category I and Category II AIFs are close-ended, with a minimum tenure of three years under the regulations, subject to permitted extensions. Category III may be open-ended or close-ended. Liquidity depends on the structure. Units are not generally redeemable on demand. Secondary transfers are subject to the fund terms and the regulations. Unlisted assets are valued under the applicable valuation framework, and exits can take time.

AIF liquidity should not be compared with a daily-liquid mutual fund without those qualifications.

Risks and fees

The principal risks are illiquidity, concentrated portfolios, valuation uncertainty, capital-call obligations, manager selection, counterparty and credit risk, leverage and derivatives where applicable, long horizons, fees and performance-linked compensation, and exit or distribution uncertainty. SEBI registration does not guarantee capital safety, returns or manager competence.

Fees typically include a management fee, fund expenses and, where applicable, a performance fee or carried interest with a hurdle rate and a distribution waterfall. Gross and net returns differ. There is no universal “2 and 20” rate; the terms are in the fund documents. For performance, distinguish committed capital, invested capital, NAV and realised distributions. IRR and investment multiples are summary measures, not guarantees.

SIF versus AIF

Both may use sophisticated strategies, which is why they are confused. They are different regulated structures.

A SIF is not a smaller AIF. It is a mutual fund product with its own permissions and investor protections. An SIF may use certain long-short strategies without having the full investment powers of a Category III AIF.

Real Estate Investment Trusts (REITs)

A REIT is a trust that owns eligible income-producing real estate. Investors buy units of the trust rather than a property directly.

The structure usually involves a sponsor, a manager, a trustee, the trust itself, and holding companies or special-purpose vehicles that hold the assets. Unit holders own units of the trust.

Underlying assets may include office parks, commercial buildings, business parks and other real-estate assets permitted by the regulations. Not every REIT holds only offices.

How investors earn. There are two possible sources: distributions from eligible cash flows, and changes in the market value of the units. Neither is guaranteed. Rental income and operating cash flow are not automatically the amount distributed; operating costs, financing, capital expenditure and other adjustments come first.

Distribution. The SEBI REIT Regulations require distribution of at least 90% of net distributable cash flows (NDCF), at least half-yearly, subject to the applicable framework. NDCF is not accounting profit. A mandatory distribution does not guarantee a fixed yield, a minimum rupee amount, a fixed unit price or capital protection.

Risks. Vacancy and occupancy, rental growth or decline, tenant concentration, lease renewals, property valuation, interest rates, borrowing and refinancing, asset concentration, unit-market liquidity, and regulatory or tax changes. A listed REIT can trade at a premium or discount to estimates of its underlying asset value.

Distribution components and tax. A distribution may contain interest, dividends, repayment of debt or capital, and other components permitted by the structure. Tax treatment can vary by component, entity and law. Do not assume the whole distribution is tax-free, and check the current income-tax position.

Infrastructure Investment Trusts (InvITs)

An InvIT provides pooled exposure to eligible infrastructure assets. Examples include toll roads, power transmission networks, renewable-energy assets and pipelines, subject to what the regulations permit for the structure.

Cash flows. Possible sources include toll collections, contracted transmission revenues, availability-based payments, tariff-linked cash flows and other project revenues. Cash flow at the asset level is not the same as the distribution to unit holders. The trust, the manager and the project SPVs sit between the asset and the unit holder.

Public and privately placed. InvIT structures differ in issuance, listing, investor eligibility and liquidity. Publicly offered InvITs are listed and have a lower minimum subscription; privately placed InvITs are not listed and have a higher minimum. Not every InvIT is exchange-traded or open to all retail investors.

Distribution. The regulations require distribution of at least 90% of NDCF. Publicly offered InvITs must distribute at least once every six months; privately placed InvITs at least once a year, subject to the applicable framework. NDCF is not accounting net profit. There is no fixed or periodic income independent of the trust’s cash generation.

Risks. Traffic volume and toll revenue, project availability, tariff or concession changes, regulatory changes, counterparty risk, operating costs, capital expenditure, borrowing and refinancing, interest-rate exposure, asset concentration, liquidity and valuation uncertainty. An InvIT is not equivalent to a government bond.

REIT versus InvIT

Both can combine income distributions with capital gains or losses. The trust structure does not remove asset-level financial risk.

Distribution yield is not total return

A cash distribution is not the same as a return. Suppose an investor buys a trust unit for ₹100. During the year the investor receives a ₹7 distribution, and at the end of the year the unit trades at ₹90. Ignoring tax and transaction costs:

• Distribution received: ₹7.
• Change in unit value: ₹90 − ₹100 = −₹10.
• Total return: ₹7 − ₹10 = −₹3, or −3% on the ₹100 invested.

The 7% cash distribution on the purchase price did not produce a positive total return. The same point applies to any income-producing structure: yield measures the cash paid, not the change in capital value. The ₹7 is not necessarily taxable interest or dividend; its treatment depends on the component.

Comparing the structures

An ETF is generally a fund that trades on an exchange; it is not a peer regulatory category to an AIF. Mutual fund minimum applications vary by scheme. The SIF and AIF thresholds are general and subject to exemptions. REIT and InvIT access depends on the offering, listing and investor eligibility. Listing does not guarantee liquidity.

Diversification depends on exposure, not labels

A portfolio holding an equity mutual fund, an equity ETF, an equity-focused SIF and a Category III AIF may still have substantial exposure to the same equity market. Holding several REITs or InvITs does not remove concentration in similar property, infrastructure, financing or interest-rate risks.

Diversification depends on the underlying economic exposures, not on the number of products or their regulatory labels.

How to select and compare

Mutual funds and ETFs

1. Decide the mandate and asset allocation. Equity or debt, domestic or international, large or mid cap. The fund should match the job and the horizon.
2. Check the benchmark and the category. A fund is measured against a benchmark; know which one, and whether it is a total-return or price-return index.
3. Decide active or passive. Low-cost broad-market index funds offer a straightforward way to obtain diversified market exposure. The appropriate choice still depends on your goals, asset allocation, time horizon and ability to bear losses.
4. Compare costs. Base expense ratio, the other cost components, direct versus regular, exit load, and for an ETF the spread.
5. For a passive fund, check tracking difference and tracking error. Both, and against the right benchmark.
6. Read the portfolio and the Riskometer. A fund with 60% in ten stocks is not diversified, whatever its category.
7. Check size and flows with care. Size can matter differently for index, mid-cap, small-cap and debt strategies; it is not a simple “bigger is better” or “smaller is better” test.
8. Read the risk disclosures and the portfolio, not only the past return. Past return is the most advertised number and the least predictive.

SIFs, AIFs, REITs and InvITs

1. Permitted strategies or underlying assets. What the structure is allowed to hold, and what it actually holds.
2. Eligibility and minimums. Who may invest, the minimum investment or commitment, and any capital-call obligation.
3. Liquidity, lock-ins and tenure. Redemption windows, close-ended terms, extensions and secondary-transfer conditions.
4. Derivative exposure and leverage. Whether the strategy uses them, and within what limits.
5. Concentration and valuation. How concentrated the portfolio is, and how unlisted or illiquid assets are valued.
6. Fees and performance-linked compensation. Management fees, expenses, carried interest or performance fees, and the hurdle and waterfall.
7. Distribution sources and sustainability, where relevant. For REITs and InvITs, what the distribution is paid from and whether it is repeatable.
8. Manager, trustee and regulatory disclosures. Read the placement document, scheme document or trust disclosures.

Not every check applies to every structure. Capital-call obligations are primarily an AIF matter; tracking difference and tracking error are primarily relevant to passive funds; occupancy and rental cash flows are REIT matters; project and concession risks are InvIT matters; and short exposure and derivatives may matter for certain SIFs and Category III AIFs.

Common mistakes

• Chasing last year’s best fund. The top performer of one period is frequently not the top performer of the next, and the flows that follow the ranking can make the fund larger and harder to run.
• Holding too many overlapping funds. Many funds with similar portfolios add complexity without meaningful additional diversification. Evaluate the underlying holdings and mandates rather than choosing an arbitrary number of schemes.
• Stopping the SIP in a fall. Pausing future instalments does not itself realise a loss on existing units. Whether to continue should depend on your cash-flow needs, horizon, risk tolerance and the suitability of the fund, not on a blanket rule to keep investing regardless.
• Ignoring the direct plan. The same portfolio at a lower cost is a free improvement.
• Treating the NAV as “cheap” or “expensive”. A ₹10 NAV is not cheaper than a ₹100 NAV. NAV is a unit size, not a valuation.
• Treating IDCW as free income. The distribution reduces the NAV. It is a withdrawal, not an addition.
• Confusing distributions with guaranteed returns. A REIT or InvIT distribution is a cash payment, not a promise of a fixed yield or a positive total return.
• Ignoring liquidity and future capital commitments. SIF and AIF units can be harder to exit than mutual fund units, and an AIF commitment may require further capital calls.

The honest summary

Pooled investments provide different ways to access securities, investment strategies, real estate and infrastructure without directly owning or managing every underlying asset. But these structures differ in their mandates, eligibility, costs, liquidity, leverage and risks. A product’s regulatory label, past returns or cash distributions alone cannot establish whether it is suitable. Understanding the underlying exposure and the terms of the investment matters more than selecting a product by name.

Our lesson on investing reality sets out what the evidence says about long-run returns. Risk management and position sizing covers how much of your capital belongs in equities at all, and taxation sets out the tax framework for the income these structures produce.
