If you could make one investment decision and leave it alone for 15–20 years, a Nifty 50 ETF would be hard to beat. It owns India’s 50 largest companies. It costs under 0.1% per year to hold. It requires no stock picking, no fund manager, no annual review of scheme performance. You buy it, you hold it, and India’s economic growth, filtered through its most consequential companies, accrues to you over time.
This is the equity instrument at the core of the allocation framework I wrote about in Farming Money. Not because I think it will make you rich fast, but because I think it is the most reliable, low-cost, behaviorally sustainable way for most people to participate in Indian equity markets over the long run.
What it actually owns
The Nifty 50 index tracks the 50 largest companies by free-float market capitalisation on the NSE. These are names you know, Reliance Industries, HDFC Bank, Infosys, TCS, ICICI Bank, Bharti Airtel, L&T, ITC, and so on. Together they represent a significant slice of India’s listed corporate earnings. When you buy a Nifty 50 ETF, you own a small fraction of each of these 50 businesses, in the same proportion that they exist in the index.
The index is rebalanced periodically. If a company grows large enough to enter the index, it gets added. If one shrinks below the threshold, it gets removed. This happens automatically within the ETF, you don’t have to do anything. The composition of the index over 20 years will look different from today’s composition, reflecting the changing landscape of Indian business.
Why cost is the most important number
The expense ratio is the annual fee charged by the fund house to manage the ETF. For Nifty 50 ETFs from major fund houses, Nippon India, HDFC, UTI, this is typically under 0.1% per year. Some are as low as 0.04–0.05%.
Compare this to an actively managed large-cap mutual fund, which typically charges 0.8–1.5% per year (direct plan). The difference sounds small. Over 20 years on a growing corpus, it isn’t. A 1% annual fee difference compounds into a meaningful gap in final wealth. And the uncomfortable truth, documented repeatedly in SEBI’s own data and in academic research globally, is that most actively managed large-cap funds do not outperform their benchmark index after costs over long periods. You’re paying more for lower (or equal) returns on average.
The ETF guarantees you index returns minus expenses. That means if the Nifty 50 returns 12% in a year, you get roughly 11.95%. The actively managed fund might return 14% in some years and 9% in others, and you won’t know in advance which years are which. The certainty of getting the index return, minus almost nothing, is what makes the ETF compelling as a long-run instrument.
Which ETF to pick
For Nifty 50 specifically, the large and liquid options are Nippon India Nifty 50 BeES (ticker: NIFTYBEES), HDFC Nifty 50 ETF (HDFCNIFTY), and UTI Nifty 50 ETF (UTINIFTY). There are others, but these three have the longest track records, the highest Assets Under Management (AUM), and the best liquidity on the exchange.
Liquidity matters because if the ETF is thinly traded, the bid-ask spread (difference between buying price and selling price) can be wide, which effectively adds a hidden cost every time you buy or sell. The large ETFs from these fund houses have tight bid-ask spreads because market makers actively provide liquidity.
Expense ratios for all three are comparable and very low. Don’t spend more than five minutes picking between them. The difference in expense ratios is smaller than the difference you’ll see from the timing of your individual purchases. Just pick one, start investing, and be consistent.
SIP versus lumpsum
For a salaried investor who gets monthly income, a SIP makes practical sense. You set up an instruction to invest a fixed amount every month, say ₹5,000, and it happens automatically. You don’t have to decide whether the market is expensive or cheap. Over time, you buy more units when prices are low and fewer when prices are high. This rupee cost averaging isn’t magical, it’s just a mechanical way to avoid timing the market, which most people do badly.
For an ETF specifically, you can’t set up an SIP through the exchange directly the way you can with mutual funds. But most brokers, including your broker, let you set up a systematic buy order that executes on a fixed date each month. It achieves the same outcome as a mutual fund SIP.
If you receive a lump sum, a bonus, an inheritance, the proceeds from selling something, and want to invest it in equity, spreading it over 6–12 monthly tranches rather than investing all at once reduces the risk of buying at a market peak. This isn’t market timing; it’s risk management for a sum that’s large relative to your ongoing savings rate. Add it to your watchlist. To buy, click on the stock name and place a limit order at the current market price. For the ETF to be held in your demat account, it will show up in your Holdings tab after settlement (T+1 days).
For the recurring order, go to Console (console.your broker.com) and set up a basket order or use the SIP feature available in the platform. The minimum amount is just the price of one ETF unit, which is typically a few hundred rupees. You can start very small and scale up.
You can also invest in Nifty 50 Index Funds through the mutual fund route (these are regular mutual fund schemes, not ETFs, that track the same index). These can be set up as SIPs directly through your broker Coin, Groww, or any mutual fund distributor. The returns are similar; the key difference is that ETFs require a demat account and trade on the exchange, while index mutual funds are transacted directly with the fund house at end-of-day NAV.
The behavioural advantage I keep coming back to
I mentioned in a post about envy how I used to make single-stock bets and would end up either selling too early or holding through large losses. The common thread in those bad experiences was that picking individual stocks invites a very specific kind of psychological trap, you develop a view, you become attached to it, and you either sell with regret when the stock continues rising or hold with hope when it doesn’t. The regret spiral either way is draining.
With a Nifty 50 ETF, there’s nothing to have a view about. You own all 50 stocks. When one does well, you benefit. When one fails, the damage is limited by the diversification. You never have to decide whether to sell or hold an individual position. This is not the intellectually stimulating approach. But intellectual stimulation in investing is often a trap, the more interesting the story, the more attached you become, and attachment is the enemy of good portfolio management.
Practical takeaway: If you don’t have a Nifty 50 ETF or Nifty 50 index fund in your portfolio today, open your broker app, search for NIFTYBEES, and buy one unit. Then set up a recurring monthly order for whatever amount you can sustain. The exact amount matters less than starting.
