The SPIVA India Year-End 2023 report has a number that should end the debate: 93.6% of large-cap active funds underperformed the S&P BSE 100 index over the trailing 10 years. That is not a bad year or a bad manager. That is a structural feature of the Indian mutual fund industry.

And yet, fund houses continue to launch new active funds. Distributors continue to push them. And retail investors continue to pay for the privilege of underperformance.

The Numbers From SPIVA

SPIVA (S&P Indices Versus Active) is the most rigorous comparison available. It is survivor-bias adjusted - it accounts for funds that were merged or closed, which are almost always the worst performers.

Horizon % of Large-Cap Active Funds Underperforming Benchmark
1 Year 53.7%
3 Years 74.2%
5 Years 83.1%
10 Years 93.6%
15 Years 96.8%

The longer the time horizon, the worse active management looks. This is not cherry-picked data - SPIVA publishes this annually for global markets and India consistently shows worse active fund performance than even the US.

The Fee Problem

A Nifty 50 index fund from UTI or HDFC charges around 0.10-0.20% expense ratio. A typical actively managed large-cap fund charges 1.5-2.0% in direct plan and 2.0-2.5% in regular plan.

That gap matters more than it looks. On a Rs. 1 crore portfolio growing at 12% pre-fee CAGR:

Expense Ratio 20-Year Value
0.15% (index) Rs. 9.2 crore
1.75% (active direct) Rs. 6.7 crore
2.25% (active regular) Rs. 5.9 crore

The difference between index and active regular plan: Rs. 3.3 crore over 20 years. The fund manager’s fee cost you more than three times your original investment.

Why Outperformance Is Nearly Impossible at Scale

The Size Problem

When a large-cap active fund manages Rs. 20,000 crore (Mirae Asset Large Cap was at Rs. 37,000 crore as of 2024), it cannot take meaningful positions in mid or small caps without moving prices. At that AUM, you are essentially buying the index but paying 10x more.

The Regulation Problem

SEBI’s 2018 fund categorization rules forced large-cap funds to invest at least 80% in the top 100 companies by market cap. Those 100 companies are almost exactly what Nifty 100 tracks. So active large-cap funds are mandated to look like the index.

The Information Problem

India’s equity markets are increasingly efficient at the large-cap level. With 40+ AMCs covering the same 100 large-cap stocks, genuine information edges are rare. Every analyst at every fund house is reading the same DRHP, attending the same analyst days, modeling the same balance sheets.

Transaction Costs

Active funds churn their portfolios. A portfolio turnover of 80-120% (common in active large-cap funds) generates brokerage, STT, and market impact costs that do not show up in the expense ratio but erode returns.

The Stars That Look Exceptional

Yes, there are funds that have beaten Nifty 50 over 10-15 years. Parag Parikh Flexi Cap, Mirae Asset Emerging Bluechip (before categorization), and a handful of mid-cap focused large-cap funds have genuine track records.

But here is the problem: identifying these funds in advance is nearly impossible. Research from S&P shows that only 30% of active funds that outperform in one 5-year period also outperform in the subsequent 5-year period. Past performance does not predict future alpha - a finding that holds across global markets and Indian data.

The fund you pick because it topped the 5-year return chart has an approximately 70% chance of underperforming over the next 5 years.

What About Mid and Small Caps?

This is the honest concession to active management. SPIVA data for mid and small-cap categories is less damning:

Category % Underperforming (10 years)
Large-cap 93.6%
Mid-cap 71.4%
Small-cap 62.3%

Active managers have more opportunity to find mispriced securities in less-covered segments of the market. A mid-cap fund manager with good research infrastructure can genuinely add value. The case for index investing is strongest in large-caps and weakest in small-caps.

The Practical Portfolio Implication

For the large-cap allocation - which should constitute 60-70% of most equity portfolios - the evidence is unambiguous: use an index fund. Nifty 50 or Nifty 100. Keep the expense ratio below 0.30%.

For the remaining 30-40% in mid and small caps, a blend of index (Nifty Midcap 150 or Nifty Smallcap 250 index funds) and one or two carefully selected active funds with consistent track records is defensible.

Bottom Line

The 93.6% figure is not a coincidence or a recent trend - it reflects structural forces that compound over time. High fees, mandatory large-cap concentration, efficient markets, and size constraints make it mathematically difficult for active managers to consistently beat a zero-decision index fund.

If you are paying 1.5-2% more per year for active management, you are betting you have found one of the 6-7% that will outperform - and betting against 15+ years of data. The Nifty 50 index fund is not exciting. It is just usually better.
