If I could make exactly one investment decision and then not touch it for twenty years, a Nifty 50 ETF would be it. It holds India’s 50 largest companies. It costs under 0.1% a year. There is no fund manager to track, no stocks to pick, no annual review of whether the scheme is still good. You buy it, and India’s largest businesses do the compounding for you.
This is the equity instrument at the centre of the allocation framework I described in Farming Money. Not because it will make anyone rich quickly, but because it is the most reliable and low-cost way I know for a normal person to participate in Indian equities over the long run.
What you actually own
The Nifty 50 index tracks the 50 largest companies by free-float market cap on the NSE. Reliance, HDFC Bank, Infosys, TCS, ICICI Bank, Bharti, L&T, ITC. Names you already know. Buying one unit of the ETF means owning a small slice of each, in the same proportion as the index.
The index rebalances itself. Companies that grow large enough enter, companies that shrink leave, and the ETF follows automatically. The index twenty years from now will look different from today’s, which is the point. You are not betting on any one business staying on top.
Why the fee matters more than the fund manager
The expense ratio on the large Nifty 50 ETFs (Nippon’s Nifty BeES, HDFC, UTI) is under 0.1% a year. Some are at 0.04-0.05%. An actively managed large-cap fund charges 0.8-1.5% on a direct plan.
One percent a year sounds like nothing. Over twenty years on a growing corpus, it is a lot of money. And the uncomfortable part, documented in SEBI’s own data and in research everywhere, is that most active large-cap funds do not beat the index after costs over long periods. So on average you pay more and get less, or the same at best.
The ETF hands you the index return minus almost nothing. Nifty returns 12%, you get roughly 11.95%. The active fund might give you 14% some years and 9% in others, and nobody knows in advance which is which.
Picking between the big ETFs: don’t spend more than five minutes on it. The expense ratios are nearly identical, and the timing of your own purchases will move your returns more than the difference between them. Pick one and be consistent. (Do check that the ETF is liquid, a wide bid-ask spread is a hidden cost. The large ones have market makers keeping spreads tight, so this mostly takes care of itself.)
SIP or lumpsum
Salaried, investing monthly: a SIP is the obvious shape. A fixed amount goes in every month, you buy more units when prices are low and fewer when high, and you never have to decide whether the market is expensive. Most people time markets badly, me included, so a mechanism that removes the decision is worth a lot.
ETFs trade on the exchange, so you cannot SIP them the way you SIP a mutual fund, but every broker lets you set up a recurring buy order that does the same job. (On Kite, this is the SIP feature; the units land in your Holdings after T+1 settlement.) If you’d rather skip the demat route entirely, Nifty 50 index mutual funds track the same index and can be SIP’d directly on Coin, Groww, or any distributor, at end-of-day NAV. Costs are marginally higher than the ETF. Fine either way.
A lump sum, a bonus or a sale proceeds, I would spread over 6-12 monthly tranches. Not because anyone can time the peak, but because investing a large sum the day before a correction is a regret that stays with you, and regret makes people do silly things with the rest of their portfolio.
The part I actually care about
I wrote in my envy post about my own single-stock bets: sell too early and watch it double, or hold too long and watch it sink. Either way, regret. That is the hidden cost of picking stocks. You form a view, you get attached to it, and then the attachment makes your decisions for you.
An index ETF gives you nothing to be attached to. One company in the 50 does badly, the damage is capped. One does wonderfully, you were already holding it. There is no sell-or-hold decision to agonise over. It is not intellectually stimulating, and that is exactly why it works. In investing, the more interesting the story, the more dangerous it usually is.
