Nifty 500 is the broader measure of NSE-listed equities. In NSE Indices’ snapshot dated March 30, 2026, it covered 92.04% of NSE-listed stocks’ free-float market capitalisation, compared with 53.73% for the Nifty 50. For the six months ending March 2026, constituents represented about 84.07% of NSE traded value for the Nifty 500 and 29.24% for the Nifty 50. Those figures make the Nifty 500 more representative if “reflects” means breadth of coverage—not a forecast of returns or a claim about every Indian exchange.
What the comparison measures
The Nifty 50 and Nifty 500 are both NSE indices weighted by free-float market capitalisation, but they cover different slices of the listed market. The Nifty 50 is a compact benchmark of 50 leading companies and important sectors. The Nifty 500 is designed as a wider universe of large companies selected using full market capitalisation and average daily turnover criteria.
Free-float weighting differs from simply weighting companies by their total size. NSE Indices applies investible weight factors to full market capitalisation to account for shares available to public investors; promoter, group-company, locked-in and identifiable strategic holdings are excluded from free float. NSE Indices’ explanation of Investible Weight Factors describes this approach.

| Measure | Nifty 50 | Nifty 500 |
|---|---|---|
| Share of NSE-listed stocks’ free-float market capitalisation, as of March 30, 2026 | 53.73% (NSE Indices) | 92.04% (NSE Indices) |
| Share of NSE traded value over the six months ending March 2026 | 29.24% (NSE Indices) | About 84.07% (NSE Indices) |
Both measures point in the same direction: the Nifty 500 spans a much larger share of the NSE market by free-float capitalisation and traded value. Capitalisation coverage concerns the market value represented; traded-value coverage concerns trading activity over the stated six-month period. Neither measure says which index will rise more in the future.
How the indexes differ in breadth and purpose
Nifty 50: a focused large-company benchmark
The Nifty 50 comprises 50 stocks and is intended to represent important sectors through a relatively small set of companies. NSE Indices gives its base period as the close on November 3, 1995, with a base value of 1,000. The official description calls it “a well diversified 50 stock index” representing important sectors of the economy (NSE Indices).
Rank #2
Nifty 500: broader listed-market coverage
The Nifty 500 represents the top companies from an eligible universe, based on full market capitalisation and average daily turnover; its index level uses free-float market capitalisation. The fact sheet dated November 28, 2025 listed 501 constituents and described semi-annual rebalancing, so that count is a dated fact-sheet figure rather than a permanent exact count. The Nifty 500 fact sheet identifies portfolio benchmarking and index-linked products as uses of the index.
Which one should you use as a market reference?
- For breadth across NSE-listed equities: Nifty 500 is the stronger of these two measures, based on the March 2026 coverage figures.
- For a concise large-company benchmark: Nifty 50 is a practical reference when the question is specifically about leading stocks rather than broad-market coverage.
- For an index fund or ETF comparison: coverage alone is not enough to judge a product. Compare current expense ratios, tracking difference, liquidity, availability and fit for your circumstances; index characteristics do not establish those product-level qualities.
NSE Indices lists fund and ETF products linked to both indexes, and its Nifty 500 fact sheet describes index funds, ETFs and structured products as possible applications. A fund or ETF tracking either index is a financial product, not the index itself.
Why older coverage figures may differ
An October 2025 Nifty 500 whitepaper reported nearly 91% of full market capitalisation, 93% of free-float market capitalisation and 80% of average daily turnover for the NSE listed-equity universe, based on six-month average data ending September 30, 2025. These are a separate, earlier snapshot with differently worded measures; they should not be combined with the March 2026 figures as though they were one undated series. The whitepaper is available from NSE Indices.

Here, more representative means wider coverage of NSE-listed market capitalisation and trading activity. It does not mean the Nifty 500 is certain to outperform, is automatically a better investment for every person, or covers every Indian-listed security. The figures answer a market-breadth question; returns, valuations, costs, taxes and personal suitability require separate comparisons.
