Choose the kind of exposure first, then compare funds that pursue the same exposure: an index fund aims to track a specified index, while an actively managed fund gives its manager discretion to try to outperform a benchmark. Neither is a universal winner. Your comparison should account for the category and benchmark, costs, performance relative to the benchmark, and how much research and decision-making you want to do.
Start with the exposure, not a fund name
An index fund is designed to replicate a specified index and deliver its performance less costs and implementation effects. It aims to track the index, not beat it, as SEBI’s guide to index mutual funds explains. An actively managed equity fund gives its manager more discretion over which securities to hold and how much to allocate to them, with the aim of outperforming a stated benchmark.
These approaches are not interchangeable just because both invest in equities. Decide which market segment and benchmark fit the comparison you want. A Nifty 50 index fund and an active large-cap fund can be considered in a broad large-cap context, but the benchmark and category need to be explicit. Mid-/small-cap and ELSS funds are distinct comparisons; do not use large-cap results to judge them.
Compare the approaches on the same terms
| What to compare | Index equity fund | Actively managed equity fund |
|---|---|---|
| Objective | Replicate a specified index. | Seek to outperform a stated benchmark through manager decisions. |
| Useful comparison set | Funds tracking the same index; compare costs and tracking record. | Funds in the same category; compare benchmark-relative returns, costs, and strategy consistency. |
| Manager discretion | Limited by the index-replication objective. | Greater discretion in security selection and portfolio weights. |
| Costs and results | Consider the expense ratio and the gap between fund and index performance. | Consider the expense ratio and other relevant scheme costs, and assess results net of costs where available. |
| Investor involvement | Exposure is relatively simple, but choosing an appropriate benchmark still matters. | Requires evaluating the manager, process, category, and whether results have been consistent across periods. |
How to evaluate an index fund
Confirm the index
Compare schemes that track the same index. A lower-cost fund tracking one index is not a like-for-like alternative to a fund tracking a different index with different constituents or market exposure.

Look at both tracking difference and tracking error
Tracking difference describes how far the fund’s realized return was from its benchmark over a period. Tracking error describes the variability of the return gap: SEBI defines it as the standard deviation of the difference between portfolio returns and benchmark returns over a specified period. A low tracking error does not, on its own, mean high returns or low absolute risk; it concerns movement relative to the benchmark. SEBI notes that tracking error can change with market conditions, portfolio adjustments, and benchmark changes. See SEBI’s tracking-error explainer.
Check current costs and disclosures
Compare the expense ratio and the fund’s disclosed tracking error and tracking difference over consistent periods. Check current scheme or asset management company disclosures and AMFI information rather than relying on an old comparison: both costs and tracking figures can change. Tracking difference matters because a fund can track steadily while still lagging its index after costs and implementation effects.
How to evaluate an active fund
Use the stated benchmark and category
Compare a fund with its appropriate stated benchmark and relevant peer category, not with an unrelated index or a different equity segment. Review multiple periods and use returns net of costs where available. A short spell of outperformance is not enough to establish that a strategy is consistently effective.
Assess the process, not just recent returns
Consider whether the fund’s strategy and portfolio choices are understandable and consistent with its stated approach. Manager discretion creates the possibility of beating a benchmark, but it also means results depend on those decisions. Avoid selecting a fund solely because it recently led its category.

Put category scorecards in context
In its SPIVA India Mid-Year 2026 scorecard, published September 10, 2026, S&P Dow Jones Indices reported that, over the 10-year period ending June 2026, 74% of Indian Equity Large-Cap funds underperformed their benchmark, 80% of Indian ELSS funds underperformed their benchmark, and 82% of Indian Equity Mid-/Small-Cap funds underperformed their benchmark. These are past, category- and horizon-specific results—not the probability that a particular fund will underperform in the future, nor a forecast of which fund will win. The scorecard compares active funds with their respective benchmarks and also reports survivorship and return dispersion. See SPIVA India Mid-Year 2026.
Choose direct or regular separately
Direct and regular describe plan and distribution choices, not whether a fund is active or index-tracking. SEBI says the plans have the same underlying portfolio but different cost structures. A regular plan is obtained through an intermediary, whose services can include advice and paperwork; intermediary commission is included in expenses. A direct plan is purchased from the AMC without an intermediary, so the investor handles research and transactions. Compare the actual plan expense and decide whether the intermediary support is useful to you. SEBI’s regular and direct mutual-fund guide includes an illustrative cost example; it is not current market-wide expense data or a return forecast.
Use a repeatable comparison checklist
- Choose the market exposure. Identify the equity category and benchmark you want to compare.
- Match like with like. For index funds, compare schemes tracking the same index. For active funds, compare schemes in the same category against their appropriate stated benchmarks.
- Compare costs. Check each scheme’s actual plan expense rather than assuming every index fund or active fund has the same cost.
- Review the right performance evidence. For an index fund, compare tracking difference and tracking error over consistent periods. For an active fund, compare benchmark-relative performance over multiple periods, net of costs where available.
- Check disclosures and strategy. Use scheme and AMC disclosures, including relevant annual reports and portfolio information. AMFI’s Investor Corner links to fund information, expense ratios, risks, and investment resources; AMFI says its material is informational and does not assess individual objectives or suitability.
- Match the choice to your needs. Weigh your goals, time horizon, risk tolerance, desired market segment, and preference for simplicity or manager discretion. For advice tailored to your circumstances, consult a qualified professional.
Where ETFs fit
An ETF can also track an index, but it trades on an exchange like a stock rather than operating like a conventional index mutual fund. SEBI notes that ETF units cannot be traded fractionally and that brokerage and demat charges may apply. These trading mechanics and costs are not identical to those of a conventional index mutual fund; see SEBI’s ETF explainer.
