Nifty 500 better reflects the breadth of equities listed on the NSE: in NSE Indices’ snapshot dated March 30, 2026, it represented 92.04% of those stocks’ free-float market capitalisation, compared with 53.73% for Nifty 50. That makes Nifty 500 the broader market proxy of the two—not a forecast of which index, or an investment linked to it, will perform better.
What “reflects India’s equity market” means here
There is no single measure of representativeness. This comparison uses breadth across NSE-listed equities, measured by free-float market capitalisation and traded value. On both measures, the cited March 2026 figures give Nifty 500 a much wider reach than Nifty 50. They describe the NSE-listed universe, not every Indian exchange or every possible definition of the country’s equity market.

How much of the NSE market each index covers
| 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) |
The capitalisation figures indicate how much of the listed market’s free-float value is represented; the traded-value figures show the share of trading value attributable to the constituents over the stated six-month period. They are different measures and should not be treated as interchangeable.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
An earlier NSE Indices Nifty 500 whitepaper used a separate snapshot based on six-month average data ending September 30, 2025: nearly 91% of full market capitalisation, 93% of free-float market capitalisation, and 80% of average daily turnover of the NSE listed-equity universe. Those differently named measures and dates should not be blended with the March 2026 statistics.

What is different about the two indexes?
Nifty 50: a compact large-company benchmark
NSE Indices describes Nifty 50 as a diversified 50-stock index representing important sectors. Its base period is the close on November 3, 1995, with a base value of 1,000. Its small constituent set makes it a focused benchmark for leading companies rather than a broad cross-section of listed stocks.
Nifty 500: a broader company universe
NSE Indices describes Nifty 500 as representing the top companies selected from an eligible universe using full market capitalisation and average daily turnover. A fact sheet dated November 28, 2025 lists 501 constituents and describes semi-annual rebalancing; 501 is the count in that dated fact sheet, not a permanent count.
Rank #2
Both use free-float weighting
Both indexes calculate their levels using free-float market capitalisation. NSE Indices’ investible weight factor methodology excludes promoter, group-company, locked-in, and identifiable strategic holdings from free float. The intent is to weight the portion of shares considered available for trading, rather than treating every share in a company as freely investible.

For readers comparing a Nifty 50 index fund with a Nifty 500 ETF or another index-linked fund, index coverage is only one consideration. It does not establish a product’s expense ratio, tracking difference, liquidity, availability, or suitability. Those require current, like-for-like information about the specific products.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Does broader coverage mean better returns?
No. A larger coverage share answers how much of the stated market an index represents under the cited measures. It does not show which index will deliver higher future returns, and the available figures do not compare performance, valuation, cost, taxes, or investor suitability. “More representative” in this comparison means broader coverage, not “better investment.”
