Every investor eventually asks whether it is worth paying a fund manager to pick stocks. The question has a long academic history, and a surprisingly clear pattern in the data. It also has caveats that are specific to India, which is why a blanket answer in either direction is usually a sign someone is selling something.
What an index fund does
An index fund doesn't try to be clever. It buys the stocks in an index, such as the Nifty 50, in the same weights, and holds them. When the index changes, the fund changes with it. Because nobody is researching companies or trading often, running costs are low, often a fraction of those of active funds.
An active fund tries to beat the index. The manager picks stocks and decides when to buy and sell. That takes a team, research and trading, and the cost comes out of your returns every year, whether the manager does well or not.
The scorecard
S&P Dow Jones Indices publishes a regular report called SPIVA (S&P Indices Versus Active) for India. It compares the share of active funds that beat their benchmark. Over the past decade of reports, a clear message repeats: in large-cap categories, most active funds have lagged the index over five and ten years, and the share that lag grows as the time period gets longer.
The exact percentages change from report to report, so check the latest edition on the S&P website rather than relying on anyone's quoted number, including ours. Two points usually hold:
- A fund that beats the index in one year has no better than a slim chance of doing it again the next.
- The funds that do beat the index over the long run are hard to identify in advance. Many of the winners of one decade are in the middle of the pack in the next.
Why costs matter so much
Suppose the market returns 12% a year before costs. An index fund charging 0.2% leaves you with about 11.8%. An active fund charging 1.5% needs to earn about 13.3% before costs just to match what you got. The manager has to be much better than the market to break even after fees, not just a bit better.
₹10,000 a month for 20 years at 11.8% grows to roughly ₹97 lakh. At 10.5%, it grows to roughly ₹82 lakh. Nothing about the investing changed except the fee, and the difference is about ₹15.5 lakh. This is why many experienced investors start with cost.
Where active management can still earn its fee
The case for index funds is strongest in large caps, where thousands of analysts watch the same few dozen companies and prices adjust quickly. It is weaker in mid and small caps, where information is thinner and a good manager may find mispriced stocks. Some active funds have beaten their benchmarks in these segments over long periods, and index options there may be newer, costlier or less liquid.
So the useful question is not "which is better?" but "where am I paying for something I can actually get?"
A simple way to combine them
Many investors use a core and satellite approach:
- Core (roughly 70 to 80% of your equity money): a low-cost index fund tracking a broad index like the Nifty 50, or a total-market style index.
- Satellite (the rest): one or two active funds in areas where you believe a manager can add value, such as mid or small caps, held for the long term.
It keeps costs down and caps the damage if your active picks disappoint.
Choosing an index fund well
Two index funds that track the same index can still differ. Look at:
- Expense ratio: lower is better. Choose direct plans.
- Tracking difference: the gap between the fund's actual return and the index return. Smaller and steadier is better.
- Fund size and track record: very small funds can be shut down or merged.
- Which index: Nifty 50 covers the largest companies; Nifty Next 50, Midcap 150 and Smallcap 250 indices go further down in size and carry more risk.
The trap in "passive"
An index fund will fall when the market falls. A 40 per cent drop in the Nifty means a 40 per cent drop in your fund. Choosing index funds doesn't remove risk; it removes the extra cost and the manager risk. You still have to stay put when the headlines turn ugly, and that is the part that decides most investors' outcomes.
