What is an Exchange-Traded Fund (ETF)? Meaning, Definition & How It Works
The exchange-traded fund arrived in India in December 2001, when Nifty BeES listed on the NSE, years after the structure had already taken hold in the United States. Since then, ETFs have grown from a niche product into one of the more visible ways Indian investors get index-linked exposure without picking stocks themselves.
An Asset Management Company creates and runs the ETF, and it is regulated the same way as any other mutual fund scheme under SEBI’s Mutual Fund Regulations.
AMFI classifies ETFs under its “Other Schemes” bucket alongside index funds and fund of funds, a category that has drawn unusually strong retail and institutional interest through 2025 and 2026.
Retail investors, pension funds such as EPFO, and high-net-worth individuals all use ETFs, though often for different reasons.
A pension fund might want low-cost, rule-based equity exposure at scale, while a retail investor in a city like Bengaluru might simply want to buy the Nifty 50 in one trade instead of fifty separate stock purchases.
Did You Know? – AMFI’s data for January 2026 shows that ETFs, index funds, and related fund of funds together pulled in a record ₹39,955 crore that month, with gold ETFs alone accounting for ₹24,040 crore of it, also a record for the category.
How Does an ETF Work?
An ETF’s mechanics run through a creation process most investors never see directly, followed by a trading process most investors already know from buying shares.
- An AMC decides on a benchmark, such as the Nifty 50 or the domestic gold price, and structures a scheme to track it.
- Large institutions called Authorised Participants exchange a basket of the underlying securities, or cash, for big blocks of ETF units known as “creation units.”
- The AMC lists these units on the NSE and BSE, where they trade in smaller, investor-friendly lot sizes throughout the session.
- Retail investors buy and sell ETF units through a broker and a demat account, at whatever price the market is offering at that moment.
- Authorised Participants keep the market price close to the ETF’s Net Asset Value by trading whenever a meaningful gap opens up between the two.
- The AMC publishes an indicative NAV through the day and discloses the full portfolio, usually daily, so holdings stay visible to investors.
Pro Tip – Before you buy, check an ETF’s average daily trading volume on the exchange. A thinly traded ETF can trade at a wider gap from its NAV, which quietly eats into your returns on both entry and exit.
Example with Real Numbers
Rohan is a 34-year-old product manager in Pune who wants low-cost exposure to India’s large-cap stocks without picking individual names.
Field | Value |
Nifty 50 ETF market price at purchase | ₹250 per unit |
Units bought | 50 |
Amount invested | ₹12,500 |
Holding period | 14 months |
Selling price | ₹290 per unit |
Rohan places the order through his broker, and the units settle in his demat account like any listed share. After 14 months, he sells all 50 units at ₹290, receiving ₹14,500, a gain of ₹2,000.
Because he held the ETF for more than 12 months, this counts as a long-term capital gain under equity taxation rules. Since ₹2,000 sits well under the ₹1.25 lakh annual exemption for equity-oriented long-term gains, Rohan owes no tax on this particular sale.
Types of ETFs
Indian ETFs generally fall into a handful of recognised categories, based on what they track.
Equity or Index ETFs
These track a stock market index such as the Nifty 50, the Sensex, Bank Nifty, or the Nifty Next 50, holding roughly the same stocks in roughly the same weights as the benchmark. They are the largest and most liquid category of ETF in India, and usually the first stop for a new ETF investor.
Gold ETFs
Gold ETFs hold physical gold or gold-backed assets and track the domestic gold price instead of an index. They let an investor gain gold exposure without storing jewellery or bars, and units can be bought or sold in small amounts through a demat account.
Debt or Bond ETFs
These invest in government securities or corporate bonds, sometimes with a fixed maturity structure, such as the Bharat Bond ETF series. They suit investors who want predictable, bond-like exposure with the same exchange-traded convenience as an equity ETF.
International or Global ETFs
A smaller set of ETFs and ETF-linked fund of funds give Indian investors exposure to overseas indices, such as the Nasdaq 100 or the S&P 500. Most retail investors reach this exposure through the fund of fund route rather than buying foreign-listed units directly.
Sectoral or Thematic ETFs
These track a single sector or theme, such as banking, IT, or metals, concentrating risk in that segment rather than spreading it across the market. Zenith’s review of the HDFC Nifty Metal ETF FOF NFO walks through how one such sector-focused, index-linked structure works in practice.
Quick ComparisonQuick Comparison
Type of ETF | What It Tracks | Typical Risk & Tax Note |
Equity / Index ETF | Nifty 50, Sensex, sector indices | Equity market risk; LTCG at 12.5% after 12 months, with a ₹1.25 lakh yearly exemption |
Gold ETF | Domestic gold price | Commodity price risk; LTCG at 12.5% after 12 months, no exemption |
Debt / Bond ETF | Govt securities, corporate bonds | Interest rate and credit risk; taxed at slab rate as short-term gains, regardless of holding period |
International ETF / FOF | Overseas indices (Nasdaq 100 and similar) | Currency and market risk; taxed per the applicable ETF or fund-of-fund wrapper rules |
Sectoral / Thematic ETF | A single sector or theme | Concentration risk; generally taxed as equity when the ETF holds mostly domestic equity |

Key Components / What to Look For
- NAV vs Market Price: the ETF’s Net Asset Value is its per-unit fair value based on underlying holdings, while the market price is what it actually trades at on the exchange. The two are usually close but can drift apart, especially in thinly traded ETFs.
- Expense Ratio (TER): the annual fee the AMC deducts to run the fund. Passive ETFs tracking well-known indices tend to sit well below the fees charged by actively managed equity mutual funds.
- Tracking Error and Tracking Difference: tracking error measures how much an ETF’s day-to-day returns wobble relative to its benchmark, while tracking difference captures the cumulative gap over a period. A consistently high number on either front suggests the fund is not doing its one job particularly well.
- Trading Volume and Liquidity: an ETF with low daily trading volume can be hard to buy or sell at a fair price, since the bid-ask spread widens when there are few active buyers and sellers.
- Underlying Index or Benchmark: knowing exactly what an ETF tracks, and how that index is built and rebalanced, tells you what you are actually buying exposure to, which matters more than the fund’s name alone.
Benefits of Investing in ETFs
- Lower Costs: because most Indian ETFs are passively managed, their expense ratios are typically a fraction of what actively managed diversified equity funds charge, which compounds meaningfully over long holding periods.
- Instant Diversification: a single ETF purchase spreads money across dozens of underlying securities in one trade, useful for a salaried investor in a city like Ahmedabad building a core portfolio without picking individual stocks.
- Trading Flexibility: unlike a regular mutual fund, which transacts once a day at closing NAV, an ETF can be bought or sold at any point the market is open, useful for investors who want more control over entry and exit price.
- Transparency: AMCs disclose ETF holdings regularly, so investors know exactly what they own, unlike some actively managed funds that reveal portfolios less often.
- Tax Efficiency for Listed Categories: since the 2024 tax changes, equity and gold ETFs benefit from the shorter 12-month holding period that applies to listed securities, rather than the longer 24-month window unlisted or physical assets face.
Risks & Limitations
- Tracking Error: an ETF’s actual return can lag or diverge from its benchmark due to fees, cash drag, or imperfect replication, so returns are rarely an exact mirror of the index.
- Liquidity Risk: niche or thematic ETFs sometimes trade in low volumes, which can widen the bid-ask spread and make it harder to exit at a fair price during stressed markets.
- Requires a Demat Account: unlike a regular mutual fund bought directly from an AMC, ETFs need a demat and trading account, which adds a small extra step and, sometimes, brokerage costs.
- Concentration Risk in Sector ETFs: a sectoral or thematic ETF lacks the built-in diversification of a broad index ETF, so a downturn in that one sector affects the entire holding.
- Premium or Discount to NAV: during volatile sessions, an ETF’s market price can temporarily trade away from its NAV, meaning the price you pay or receive is not always the fund’s true underlying value.
Important – A common mistake is treating every ETF as equally liquid. Before investing, check the average daily trading volume on the NSE or BSE, not just the fund’s total assets under management.
Frequently Asked Questions
What is an ETF in simple terms?
An ETF, or exchange-traded fund, is a basket of stocks, bonds, or an asset like gold, packaged into a single fund and listed on a stock exchange. You buy and sell it just like a regular share, through your broker and demat account, and its price moves throughout the trading day.
How is an ETF different from a regular mutual fund?
A regular mutual fund is bought and sold once a day at its closing NAV, directly from the AMC or a distributor. An ETF trades continuously on the NSE or BSE at live market prices, and buying or selling it needs a demat account, unlike most regular mutual fund purchases. For a broader look at how the two fit together in a portfolio, see Zenith’s comprehensive guide to mutual funds in India.
Do I need a demat account to invest in ETFs?
Yes. Since ETF units trade on stock exchanges like shares, you need both a demat account to hold the units and a trading account to place buy and sell orders through a broker.
How are ETFs taxed in India?
Taxation depends on what the ETF holds. Equity and gold ETFs, being listed, qualify for long-term treatment after just 12 months, with equity ETFs taxed at 12.5% above a ₹1.25 lakh yearly exemption and gold ETFs at 12.5% without that exemption. Debt-oriented ETFs are taxed at your income slab rate as short-term gains, regardless of how long you hold them, following the rules the government sharpened in the 2024 Budget.
Can I do a SIP in an ETF?
Not directly on most exchanges, since ETF trading depends on live market orders rather than a fixed monthly debit. Investors who want SIP-style, rupee-cost-averaged exposure to an ETF’s underlying index usually do it through a fund of fund route instead, similar to what Zenith’s SIP Advisors service helps set up.
Are gold ETFs a better option than physical gold?
Gold ETFs remove storage and purity concerns, trade at prices close to the domestic gold rate, and now enjoy a shorter 12-month holding period for long-term tax treatment since they are exchange-listed. Physical gold still appeals for cultural or gifting reasons, but as a pure investment, gold ETFs are usually the more cost-efficient route.
What is tracking error and why does it matter?
Tracking error measures how closely an ETF’s returns follow its underlying index or asset over time. A higher tracking error means the fund is doing a weaker job of replicating what it claims to track, which can quietly cost investors returns even when the index itself performs well.
When should I consider adding ETFs to my portfolio?
ETFs work well when you want low-cost, rule-based exposure to a market segment, whether that is broad equities, gold, or a specific sector, and you are comfortable managing a demat account. A financial plan built around your goals and risk profile, such as the kind Zenith’s investment planning framework follows, can help you decide how much of your portfolio should sit in ETFs versus other structures.
