If Your Only ETF Is Nifty 50, You're Missing Most of the Market
The Nifty 50 ETF is the default first ETF for most Indian investors — and rightly so. It's cheap, liquid, and broadly representative. But the Indian ETF market has matured well beyond it. As of 2026, there are 50+ equity ETFs covering large-cap-plus, midcap, smallcap, sectoral, factor, and international exposure. A few of them deserve a place in a serious portfolio. Most don't.
What SEBI Defines as an Equity ETF
An equity ETF is an open-ended scheme that tracks a specified equity index, with at least 95% of assets invested in securities of the underlying index. Units trade on the exchange like a stock and you need a demat account to buy them. Pricing happens intraday, NAV is computed end-of-day, and the difference between the two creates small premiums and discounts that the AMC's authorised participants arbitrage away.
Compared to an index fund (which tracks the same index but is bought through the AMC at NAV with no demat), ETFs typically have lower expense ratios but require active monitoring of liquidity and tracking error.
The Categories Worth Knowing
Large-Cap-Plus: Nifty Next 50
The next 50 large-caps after the Nifty 50. Names like Adani Power, DLF, ABB India, Bajaj Holdings, GAIL — companies on the cusp of joining the Nifty 50. Historically, this index has outperformed the Nifty 50 by 1%–2% CAGR over 15+ year windows, with somewhat higher volatility.
Common products: Nippon Nifty Next 50 Junior BeES, ICICI Prudential Nifty Next 50 ETF, SBI Nifty Next 50 ETF. Expense ratios 0.10%–0.30%.
Midcap and Smallcap
Nifty Midcap 150 ETFs and Nifty Smallcap 250 ETFs cover the next layer of listed companies. Tracking error is structurally higher in this space (1%–2% versus 0.1%–0.3% for Nifty 50 ETFs) because of trading costs in less liquid stocks.
Returns over the last decade have been 14%–17% CAGR for midcaps and 13%–16% for smallcaps, with substantially higher drawdowns — peak-to-trough of 50%+ in 2008 and 2020. These ETFs make sense only if you can hold for 10+ years.
Sectoral and Thematic
- Bank Nifty ETFs: Concentrated bet on Indian banking — HDFC Bank, ICICI Bank, SBI, Axis, Kotak. Useful only if you want a directional banking view.
- Pharma ETFs and IT ETFs: Sectoral exposure for satellite allocations.
- PSU Bank ETFs and CPSE ETFs: Government-owned company exposure. Cyclical, often deeply unloved, occasionally rewarding.
Sectoral ETFs should rarely cross 5%–10% of a retail portfolio. They are amplifiers, not foundations.
International ETFs
Indian-listed ETFs that track US indices give rupee-cost INR exposure to global equities without an LRS remittance:
- Nasdaq 100 ETFs: Motilal Oswal Nasdaq 100 ETF, others. Mega-cap US tech exposure.
- S&P 500 ETFs: Broader US large-cap exposure.
Note: International ETFs are taxed as non-equity in India (slab rate, no LTCG advantage), and SEBI's overseas investment cap has periodically forced AMCs to suspend fresh subscriptions. Check the latest status before relying on them.
Factor / Smart Beta
Low Volatility, Momentum, Quality, Equal Weight, and Value indices are now available as ETFs. Live data in India is too short for confident conclusions, but global research suggests factor exposures can add 1%–2% CAGR over very long horizons in exchange for periods of significant underperformance.
Returns Snapshot (10-Year CAGR, Approximate)
| Nifty 50: 12%–13% / -38% |
| Nifty Next 50: 14%–15% / -45% |
| Nifty Midcap 150: 15%–17% / -50% |
| Nifty Smallcap 250: 13%–16% / -55% |
| Nasdaq 100 (INR): 16%–18% / -35% (currency aided) |
Past returns are not a forecast — but the relative shape (more volatility for more return) is structural.
When ETFs Beat Index Funds
- You already have a demat account and don't mind placing exchange orders.
- You're investing lump sums above ₹50,000. Below that, the bid-ask spread eats into your edge over an index fund.
- You want intraday execution — for example, deploying a windfall on a market dip.
- You want the absolute lowest expense ratio. Nifty 50 ETFs at 0.04%–0.05% are cheaper than any index fund.
When to Stick With Index Funds Instead
- You SIP every month. Index funds via mutual fund platforms accept ₹500 SIPs without per-transaction brokerage. ETFs charge brokerage and STT on every purchase.
- You don't watch markets and won't check liquidity. Some midcap and smallcap ETFs in India trade at 0.5%–1% premiums or discounts to NAV during volatile sessions.
- You want automatic rebalancing. Index funds let you switch between schemes within a fund house without market timing.
Tax Treatment
For Indian equity ETFs (including Nifty 50, Next 50, midcap, smallcap, sectoral, and Bank Nifty ETFs):
- LTCG (held over 12 months): 12.5% on gains above ₹1.25 lakh per year.
- STCG (held 12 months or less): 20% flat.
For international equity ETFs (Nasdaq 100 in India, S&P 500 in India), tax treatment follows the non-equity / debt fund regime — gains taxed at slab rate regardless of holding period, with no LTCG advantage. This is the single most important tax fact most investors miss.
How to Evaluate an Indian ETF
- Tracking error under 0.5% for large-cap ETFs, under 1% for mid/small/sectoral.
- Average daily volume above ₹5 crore — anything thinner and you'll struggle with bid-ask spreads.
- Premium/discount to iNAV under 0.3% on most trading days. Larger gaps signal weak market-making.
- Expense ratio benchmark: Nifty 50 ETFs 0.04%–0.10%; Next 50 ETFs 0.10%–0.30%; midcap and smallcap ETFs 0.20%–0.40%; sectoral ETFs up to 0.50%.
- AUM above ₹500 crore for niche ETFs. Smaller schemes can get wound up or merged.
Frequently Asked Questions
Do I need a demat account to invest in ETFs?
Yes. ETFs trade on exchanges and have to be held in demat form. Index funds, by contrast, can be held with the fund house directly without a demat account.
Are ETFs always cheaper than index funds?
Usually but not always. The expense ratio is lower, but you pay brokerage, STT, exchange charges, and a bid-ask spread on every ETF transaction. For small monthly SIPs, an index fund can be cheaper in total cost.
Can I do an SIP in an ETF?
Some brokers offer "ETF SIPs" that automatically place market orders on a chosen day. These work, but you give up control over execution and may pay brokerage on each leg. For most retail SIPs, an equivalent index fund is simpler.
Why is there a Nifty 50 ETF AND a Sensex ETF?
The Nifty 50 has 50 stocks; the BSE Sensex has 30. Composition overlap is high but not identical. Sensex ETFs exist because BSE-linked products have separate benchmarking and are sometimes preferred by treasury and EPFO mandates. For most retail investors, picking one is enough.
Should I add Nifty Next 50 if I already own Nifty 50?
Adding Next 50 alongside Nifty 50 gives you exposure roughly equivalent to the Nifty 100 — basically a cleaner large-cap-plus-emerging-large-cap package. Many investors hold both in roughly 70:30 or 60:40 ratio.
Are Nasdaq 100 ETFs in India tax-efficient?
Less tax-efficient than they used to be. Indian-listed international ETFs are taxed as non-equity funds — slab rate on gains, no LTCG advantage. They still offer global diversification and rupee-cost INR exposure, but the tax math now favours holding domestic equity longer.
The Bottom Line
Stick with a Nifty 50 ETF or Nifty 500 index fund as your core. Then, if you have a 10+ year horizon and want a more diversified equity engine, add a Nifty Next 50 ETF and possibly a midcap ETF. Sectoral and thematic ETFs are satellite tools — useful occasionally, dangerous if they become 30% of your portfolio. International ETFs are now tax-disadvantaged but still earn their place for genuine global diversification. The point of going beyond Nifty 50 is not to maximise returns — it's to make sure you actually own the parts of the market that aren't in Nifty 50.
