An active fund employs people to decide what to own. A passive fund owns whatever the index says, in whatever proportion the index says, and employs almost nobody to think about it.
The question underneath is uncomfortable and worth asking plainly: can a human reliably beat the market after fees? The evidence has an answer, and it is more nuanced than either camp admits.
The arithmetic that starts the argument
Before any data, there is a piece of logic that is simply true.
All investors collectively own the whole market, so collectively they earn the market return before costs. Active investors as a group therefore earn the market return before costs too — and after costs, they must as a group earn less than the index, by exactly the amount they spend on fees and trading.
This is not a claim about skill. It is accounting. It means active management is inherently a zero-sum contest for a below-average average, and the only question is whether your manager is on the winning side of it.
What the Indian evidence shows
S&P’s SPIVA India scorecards measure Indian active funds against their own benchmarks. The large-cap picture has been persistently uncomfortable: across five- and ten-year horizons, roughly three-quarters to four-fifths of active large-cap funds fail to beat the index they are measured against, and the share that lags tends to rise as the window lengthens.
Two honest caveats before that becomes a slogan:
- The picture is less settled in mid and small caps, where research coverage is thinner, dispersion between companies is wider, and a manager has more to work with. Active management has a better case the further you go down the market-cap scale.
- Survivorship matters. Funds that closed or merged were once in these averages. Scorecards that adjust for it look worse for active management, not better.
Why large-cap alpha is so hard
The large-cap universe is a hundred companies covered by every analyst in the country. Information reaches everyone at once, and a durable informational edge is extremely difficult to hold.
Meanwhile the fund starts the year roughly 1 to 1.5 percentage points behind an index fund on cost alone. To beat the index, the manager must first earn back the fee, then add value. That is a headwind compounding annually, and it is why the expense ratio is close to the whole story in large caps.
The part that gets skipped: persistence
Even where active funds do win, the practical question is whether you can identify them in advance.
Persistence studies consistently find that a fund’s presence in the top quartile over one period is a weak predictor of the next. Which is the real problem with “just pick the good ones”: the list of good ones is only knowable afterwards, and picking on past returns is how investors end up buying last year’s winner.
Where active still earns its fee
This is not an argument that active management is worthless. It earns its place where the conditions favour it:
- Less efficient corners — mid and small caps, where diligence finds things screens do not.
- Debt, where credit selection is genuine work and a passive debt index is a poor instrument.
- Downside management. An index fund falls the entire way, by design. A manager who holds cash or defensive positions can cushion a drawdown — and behaviourally, the portfolio you keep holding beats the theoretically superior one you abandon.
- Genuinely differentiated mandates where the benchmark is a poor description of what the fund is trying to do.
Pitfalls to avoid
- Do not treat “passive” as “safe”. An index fund carries the full market drawdown and inherits the index’s concentration — a Nifty 50 fund is heavily weighted to financials because the index is.
- Do not call a narrow thematic index passive. A sector or factor index is an active bet in passive packaging, with concentration risk and none of the discretion.
- Do not judge an active fund on one good year. Use multi-year rolling returns against the correct peer group, not a trailing headline.
- Do not pay active fees for closet indexing. A high R² and low tracking error against the benchmark means you are buying the index at four times the price.
Key takeaway
Costs make active management a losing proposition on average, and the Indian large-cap data bears that out emphatically. The sensible response is not ideological: index the large-cap core where the odds are steepest and the evidence is clearest, and be selective, patient and cost-conscious with active exposure where inefficiency actually exists. What you must not do is pay active fees for index performance.
