Benchmarks for Equity Schemes

A benchmark is a reference index or composite that represents the market segment a mutual fund aims to replicate or outperform. For equity schemes, the benchmark is usually a broad market index such as the Nifty 50 or BSE Sensex, but it can also be a sector‑specific index or a custom blend of indices.

The primary purpose of a benchmark is to provide investors with a yardstick to judge the fund manager’s skill. If a scheme consistently beats its benchmark after costs, it indicates value‑added management; if it underperforms, the manager may not be adding value.

In the NISM exam, questions often ask you to identify the appropriate benchmark for a given fund or to calculate the fund’s excess return over its benchmark. Remember that SEBI mandates the benchmark to be disclosed in the scheme’s offer document.

Benchmarks can be classified into three broad categories: Broad‑market indices, Sector or thematic indices, and Custom or blended benchmarks. Broad‑market indices track the overall equity market and are used for large‑cap or diversified equity funds. Sector indices follow a specific industry such as IT or Pharma and are suitable for sector‑focused schemes.

Custom benchmarks are created by fund houses by assigning weights to multiple indices to reflect the fund’s unique asset allocation. For example, a fund that invests 60% in large‑cap and 40% in mid‑cap may use a blended benchmark of 60% Nifty 50 + 40% Nifty Midcap 150.

Exam questions may present a fund’s investment objective and ask you to select the most appropriate benchmark from a list. Knowing the classification helps you eliminate wrong options quickly.

The selection process follows three key criteria: (1) the benchmark must represent the same asset class, (2) it should reflect the fund’s investment style and market‑cap focus, and (3) it must be transparent and widely recognized. SEBI’s Mutual Fund Regulations require the benchmark to be disclosed and to remain unchanged unless a justified change is communicated to investors.

Practically, a large‑cap fund will use Nifty 50, a mid‑cap fund will use Nifty Midcap 150, and an IT‑focused fund will use Nifty IT. If a fund uses a custom blend, the composition of the blend must be disclosed in the scheme information document.

For the exam, remember the hierarchy: broad‑market → sector → custom. When a question gives the fund’s objective, match it to the nearest index in this hierarchy.

Performance comparison is usually expressed as excess return, i.e., the difference between the scheme’s total return and the benchmark’s return over the same period. This simple subtraction captures whether the manager added value after accounting for market movements.

When the scheme distributes dividends, the total return includes dividend yield, but the benchmark return is typically price return only. For exam purposes, the syllabus assumes total return for both unless otherwise specified.

Understanding excess return helps you answer scenario‑based questions where you must decide if a fund’s performance justifies its expense ratio or if a switch recommendation is warranted.

SEBI’s Mutual Fund Regulations (2016) require every equity scheme to disclose its benchmark in the Scheme Information Document (SID) and the Key Information Memorandum (KIM). The disclosed benchmark must be appropriate to the scheme’s investment objective and cannot be changed without prior approval from the regulator and a formal communication to investors.

Additionally, the fund house must report the scheme’s performance relative to the benchmark on a monthly and annual basis. This ensures transparency and enables investors to monitor excess returns over time.

For the exam, remember the two mandatory disclosures: (i) benchmark name and (ii) performance comparison in the SID/KIM. Questions may ask which document contains the benchmark information.

One frequent error is comparing a fund’s return to a benchmark with a different risk profile, such as using a large‑cap index for a small‑cap fund. This leads to misleading conclusions about manager skill.

Another mistake is ignoring dividend yields when the benchmark is a price‑only index. The resulting excess return may be understated.

Exam candidates should also avoid treating absolute return numbers as the only performance metric; the relative return (excess return) and risk‑adjusted measures are equally important.

A well‑chosen benchmark builds investor confidence because it shows the fund is being measured against a relevant market standard. Conversely, a poorly matched benchmark can create the illusion of under‑performance even when the fund is delivering appropriate returns for its risk level.

Distributors are required by SEBI to disclose the benchmark during the sales process. Mis‑representing the benchmark can attract regulatory action and damage the distributor’s reputation.

In the NISM exam, you may be asked to evaluate a distributor’s compliance with disclosure norms or to recommend a benchmark for a new scheme based on its stated objective.
