Benchmark
Also written Benchmark index · Performance benchmark
The independently published index a scheme's performance is measured against, chosen to match its investment objective, asset allocation and strategy, and disclosed in the Scheme Information Document.
In plain language
A scheme returned 14 per cent. Good or bad? The question is unanswerable until you know what a passive investor in the same kind of portfolio would have earned over the same period. That comparator is the benchmark.
For an index fund the choice is trivial — the index it tracks. For everything else it is a judgement, made by the AMC in consultation with the trustees, written into the Scheme Information Document, and reported alongside the scheme's past performance for the same period.
A benchmark only works if it is genuinely comparable and genuinely independent. The workbook is explicit on both: it must be in sync with the scheme's investment objective, its asset allocation pattern and its investment strategy, and it must be calculated by an independent agency, transparently, and published regularly.
How it works
SEBI standardised the structure by circular of 27 October 2021, effective 1 January 2022. Income/debt and growth/equity schemes now carry two benchmarks: a Tier-1 benchmark, one broad market index per index provider for each scheme category, and a Tier-2 benchmark, bespoke to the fund manager's style or strategy within that category. Hybrid, solution-oriented, thematic, sectoral, index and exchange traded funds carry a single benchmark. Every one of them must be a Total Return Index.
The choice within a category is driven by scheme type, investment universe and portfolio concentration. A sectoral fund takes a sectoral index; a large-cap fund takes Nifty 50 or the Sensex; a fund that will hold 300 stocks takes a broad index such as Nifty 500 or S&P BSE 500 rather than a 30-stock one.
Hybrid schemes get a blend. A scheme holding about 65 per cent equity can be benchmarked to a synthetic index of 65% S&P BSE Sensex + 35% I-Bex. Separately, every scheme must also disclose returns against a short list of standard benchmarks — Sensex or Nifty for equity schemes, the 1-year T-Bill for debt schemes of up to one year duration and arbitrage funds, and the 10-year dated GoI security for other debt schemes.
A worked example
An aggressive hybrid scheme runs 70 per cent equity and 30 per cent debt. Its blended benchmark is therefore 70% of an equity TRI and 30% of a bond index.
Over the financial year:
| Component | Weight | Index return | Contribution |
|---|---|---|---|
| Equity index (TRI) | 70% | 14.00% | 9.80% |
| Bond index | 30% | 7.50% | 2.25% |
| Blended benchmark | 12.05% | ||
| Scheme return | 12.40% |
The fund manager added 0.35 percentage points. On a corpus of Rs 4,200 crore that is about Rs 14.7 crore of value over the benchmark — real, but thin enough that it deserves a second look at how much extra risk was taken to get it.
Now benchmark the same scheme lazily against the Nifty 50 alone, which returned 14.00%. The scheme appears to have lagged by 1.6 percentage points and the manager looks poor. Nothing about the portfolio changed; only the comparator did. That is why the SID has to name the benchmark in advance.
Why NISM asks about it
Chapter 11 (Mutual Fund Scheme Performance) opens with benchmarks and spends sections 11.3 to 11.6 on how they are chosen for equity, debt, hybrid, gold, real estate and international schemes. Expect questions on the requirements a credible benchmark must meet, who decides it (the AMC in consultation with the trustees), the two-tier structure, and matching a scheme type to an appropriate index. The standard-benchmark table is a favourite for straight recall.
Common exam traps
- Every benchmark must be a Total Return Index, not a price return index. This has been the rule since 1 February 2018.
- The AMC picks it, with the trustees — not SEBI, and not the registrar. It can be changed later, but the change must be justified and documented.
- Tier-1 reflects the category; Tier-2 reflects the manager's style. The mandatory Information Ratio disclosure uses the Tier-1 benchmark.
- Beating the benchmark is not proof of skill. Two schemes sharing a benchmark can be running quite different risk, which is why Chapter 11 then moves on to Sharpe, Treynor and alpha.
- A sector fund does not belong against a diversified index, and a mid-cap fund does not belong against the Sensex. Matching the universe is the whole exercise.
- The standard benchmarks are an extra disclosure required for comparability — they do not replace the scheme's own benchmark.
