Chapter 10: Indices and Benchmarking
A financial market index is a statistical measure that tracks the performance of a defined basket of securities, serving as a market barometer and performance benchmark.
Core Index Construction Methodologies

| INDEX WEIGHTING METHODOLOGY MATRIX |
+--------------------------+-------------------------------------+-----------------------------------+
| METHODOLOGY | CALCULATION MECHANICS | EXAMPLES & ATTRIBUTES |
+--------------------------+-------------------------------------+-----------------------------------+
| **Free-Float Market-** | Weights securities by market value | Nifty 50, S&P BSE Sensex, S&P 500.|
| **Capitalization** | of publicly tradable shares. | Self-rebalancing; captures size. |
+--------------------------+-------------------------------------+-----------------------------------+
| **Price-Weighted** | Weights securities based solely on | Dow Jones Industrial Average. |
| | absolute per-share stock price. | Distorted by stock splits. |
+--------------------------+-------------------------------------+-----------------------------------+
| **Equal-Weighted** | Assigns identical percentage weight | Nifty 50 Equal Weight Index. |
| | to every constituent security. | Higher exposure to small/mid caps.|

Price Return Index (PRI) vs. Total Return Index (TRI)
- Price Return Index (PRI): Tracks only the capital price movements of constituent stocks, ignoring dividend cash payouts.
- Total Return Index (TRI): Assumes that all dividend and cash distributions are fully reinvested into the index. SEBI mandates that all investment performance benchmarks must use the Total Return Index (TRI) to provide an honest, unmanipulated benchmark comparison.
Benchmarking fixed income and alternative investment strategies requires specialized indices that reflect yield curve dynamics, credit spreads, and illiquid asset returns.
Fixed Income and Bond Market Indices
- Sovereign G-Sec Indices: Benchmark the performance of sovereign debt across distinct maturity buckets (e.g., CRISIL 10-Year Gilt Index, CRISIL 1-Year T-Bill Index).
- Corporate Bond Indices: Track the composite performance of AAA, AA+, and AA-rated corporate bonds, reflecting credit spread movements over sovereign debt.
- Target Maturity Index: Benchmarks target maturity debt funds by holding SDLs and G-Secs matching specific maturity horizons.
Challenges in Benchmarking Alternative Assets
Unlike public equities that trade continuously on liquid orderbooks, private equity and venture capital assets lack daily pricing. Private market benchmarking relies on pooled vintage-year cash-flow comparisons (Public Market Equivalent [PME] analysis) to evaluate whether a private fund generated genuine illiquidity alpha over public markets.
To provide investors and institutional allocators with standardized, comparable performance data, SEBI established a mandatory Performance Benchmarking Architecture for all registered AIFs.
SEBI Performance Benchmarking Mandates
- Accredited Benchmarking Agencies: SEBI appointed recognized rating agencies (such as CRISIL and ICRA) to compute industry benchmarks semi-annually.
- Vintage-Year Segmentation: AIFs are segmented into peer comparison groups based on:
- AIF Category (Cat I, Cat II, Cat III).
- Core Strategy (VC, Private Equity, Private Debt, Long/Short Equity, Real Estate).
- Vintage Year (the calendar year of the fund's First Close).
- Mandatory Marketing Disclosure: Whenever an AIF presents its historical track record or projected returns in marketing pitch books or PPMs, it must mandatorily present the official benchmark quartile performance alongside its own figures.
