S&P 500 as an Indian Mutual Fund Benchmark

The S&P 500 (Standard and Poor’s 500) is the most widely referenced large-cap US equity benchmark, covering approximately 500 of the largest publicly listed US companies by market capitalisation. In the context of Indian mutual fund investing, the S&P 500 – specifically its total return variant – serves as the benchmark for Indian AMC-offered feeder funds and fund-of-funds (FoFs) that provide Indian investors with exposure to US large-cap equities. The index is maintained by S&P Dow Jones Indices, a division of S&P Global.

Publisher

S&P Dow Jones Indices is a joint venture between S&P Global (formerly McGraw-Hill Financial), CME Group, and News Corp, established in 2012 to consolidate the S&P and Dow Jones index families. S&P Dow Jones Indices administers over 1 million indices globally. The S&P 500 itself dates to 1957 in its current form (though the S&P 90 precursor dates to 1926) and is maintained by the S&P U.S. Index Committee.

S&P 500: index structure

Constituent selection

The S&P 500 does not mechanically include the 500 largest US stocks; it is a committee-selected index with the following eligibility criteria:

• Market capitalisation: minimum USD 20 billion (unadjusted market cap threshold, revised periodically).
• Liquidity: minimum annual dollar value traded of 1.0x the adjusted market cap; minimum float-adjusted market cap of USD 18 billion.
• Domicile: incorporated and headquartered in the United States.
• Exchange listing: listed on the NYSE, NYSE American, NASDAQ, or CBOE BZX.
• Financial viability: must have positive earnings (as reported GAAP earnings) over the most recent quarter and the most recent four quarters combined.
• Float: must have at least 50% of shares available for public ownership (free float).

The S&P 500 Index Committee meets regularly to review eligibility and to add or remove companies. Unlike the NIFTY 50 or BSE 100, which are purely rules-based, the S&P 500 has a qualitative committee-selection layer.

Weighting

The S&P 500 uses free-float market capitalisation weighting. As of 2024-25, the index is highly concentrated at the top:

• The top 10 companies (Microsoft, Apple, NVIDIA, Amazon, Meta, Alphabet, Berkshire Hathaway, Eli Lilly, JPMorgan Chase, and others depending on the period) collectively account for approximately 30-35% of the total index weight.
• The technology sector (information technology, communication services, and select consumer discretionary) collectively represents 35-45% of the index.
• Individual stock cap: there is no explicit single-stock weight cap in the S&P 500, unlike the NIFTY 50.

Rebalancing

The S&P 500 is rebalanced quarterly (in March, June, September, December) with constituent additions and deletions announced with advance notice.

TRI variant for Indian MF benchmarking

Indian mutual funds that invest in US equities through the S&P 500 use the S&P 500 Total Return Index as their benchmark. This includes both dividend reinvestment (assuming gross dividends are reinvested) at the index level. The S&P 500 Total Return Index is published by S&P Dow Jones Indices and is the standard reference for performance measurement.

For Indian investors, the benchmark return is typically presented in two ways:

1. USD total return: the index return in US dollar terms.
2. INR total return: the index return converted to Indian rupees using the prevailing INR/USD exchange rate.

The INR return is higher than the USD return whenever the Indian rupee has depreciated against the US dollar, which has been the structural trend over most multi-year periods (the rupee has depreciated from approximately Rs 45/USD in 2005 to approximately Rs 83-85/USD in 2024-25).

Currency dimension

The currency effect is a critical dimension for Indian investors benchmarking against the S&P 500:

• Rupee depreciation benefit: a 3-4% annual rupee depreciation (the long-run average) adds 3-4 percentage points to the INR return from S&P 500 investments.
• Hedging costs: Indian FoFs and feeder funds generally do not hedge the INR/USD exposure, as hedging forwards and options carry a cost equal to the interest rate differential (currently approximately 4-5%), which would entirely negate the depreciation benefit.
• Rupee appreciation risk: in short periods (2017, 2023-24), rupee appreciation against the dollar has reduced INR returns below USD returns, making unhedged US funds disappointing in the short term.

Historical returns

Approximate S&P 500 Total Return Index CAGR:

The S&P 500 has significantly outperformed the NIFTY 50 TRI in USD terms over the past decade, driven by the concentration of large US technology companies (especially from 2017 onwards). However, historical outperformance is not guaranteed to persist, and concentration in a small number of mega-cap technology stocks creates significant concentration risk.

Sectoral composition

Indian mutual fund schemes benchmarked to S&P 500

Under SEBI’s overseas investment framework, Indian AMCs can offer feeder funds and FoFs that invest in offshore funds or ETFs tracking the S&P 500. Examples:

• Motilal Oswal S&P 500 Index Fund: a direct index fund investing in Motilal Oswal’s offshore S&P 500 replication vehicle.
• ICICI Prudential US Bluechip Equity Fund: a FoF investing in the Franklin US Opportunities Fund.
• SBI International Access - US Equity FoF: a feeder fund accessing US equity through the Amundi S&P 500 ESG ETF.
• Nippon India US Equity Opportunities Fund.
• Kotak Global Emerging Market Fund (partial S&P 500 exposure).
• HDFC Developed World Indexes FoF.

The S&P 500 TRI (USD) is the standard benchmark in fund documentation; Indian rupee equivalent returns are disclosed as supplementary information.

Regulatory context

SEBI has imposed limits on overseas investments by Indian mutual funds:

• Industry aggregate limit: USD 7 billion (for overseas ETFs) and USD 1 billion per AMC.
• Overseas active fund limit: separate USD 1 billion per AMC, USD 6 billion industry limit.

These limits have occasionally been reached, causing temporary suspension of new subscriptions to US equity feeder funds. SEBI and the RBI periodically review these limits in the context of India’s foreign exchange policy.
