Nifty 50 can trail broader earnings growth in some periods, but the evidence does not show that it always does—or that its market-cap composition alone causes the gap. NSE’s FY26 figures show slower aggregate profit growth for Nifty 50 than for Nifty 500, while Q1 FY26 comparisons show that the result changes with the metric and comparison group.
What the FY26 figures show
For FY26, aggregate profit after tax (PAT) grew 9.1% for Nifty 50 and 15.4% for Nifty 500, according to NSE data reported by The Economic Times in July 2026. Over FY17–FY26, the same report puts annualized PAT growth at 12.5% for Nifty 50 and 16.9% for Nifty 500 excluding Nifty 50.
These are different comparisons: the FY26 figure compares Nifty 50 with Nifty 500, which includes Nifty 50; the decade-long CAGR compares Nifty 50 with the rest of the Nifty 500. The distinction matters because results for the full index blend the earnings of its largest constituents with those of the wider group.
Why market-cap composition might matter
Nifty 50 is weighted by free-float market capitalisation, a method NSE says has applied since June 26, 2009. In practice, companies with more tradable market value have more influence on index-level measures than smaller constituents. NSE Indices reported that Nifty 50 represented 53.73% of NSE free-float market capitalisation as of March 30, 2026.
That 53.73% is market coverage, not the index’s share of corporate profits. Market-cap weight and profit contribution measure different things: one reflects the value of tradable shares, while the other reflects earnings. A large company may carry considerable index weight yet grow profits more slowly than smaller firms.
Composition is therefore a plausible way for an index to diverge from the earnings growth of a broader company group. Sector mix can also matter. NSE Indices’ 2026 white paper notes differences between Nifty 50 sector exposure and the broader listed NSE universe, including relatively higher Financial Services exposure in Nifty 50. But the available figures do not isolate how much of the observed growth gap is caused by weighting, sector exposure, individual company results, or other factors.
Why the answer changes with the metric
Aggregate PAT growth, median company growth, index EPS growth, and an index’s share of total profits answer different questions. Aggregate growth is affected by the size of each company’s profit base; the median describes the middle constituent; profit share measures contribution to a total. One cannot substitute for another.
Q1 FY26: aggregate and median results diverged
NSE’s Q1 FY26 review reported aggregate PAT growth of 13.2% for Nifty 500 and 11.4% for Nifty 500 excluding Nifty 50. Yet median PAT growth was 9.9% for Nifty 50 and 9.2% for Nifty 500. On the median measure, Nifty 50 was ahead of the broader group, even as Nifty 500’s aggregate growth was higher.

NSE also said Nifty 50 contributed 60% of overall year-over-year PAT growth in that quarter, underscoring that a group can account for a large share of incremental profits without having the highest median growth rate.
Q3 FY26: Nifty 50 profit share declined
NSE’s Q3 FY26 review said Nifty 50’s share of Nifty 500 profits fell from 54% in FY25 to about 51% in Q3 FY26, with mid-cap companies driving the wider earnings contribution. This is a change in profit share, not a direct comparison of growth rates; a group’s share can fall even while its profits continue to rise if the rest grows faster.
Q1 FY27: analyst commentary pointed to faster mid- and small-cap growth
Q1 FY27 analyst commentary by Nitin Bhasin and Bharat Arora reported aggregate PAT growth of 16% for large caps, 31% for mid-caps, and 29% for small caps. It also attributed about half of incremental PAT to Metals, BFSI, and IT. These are analyst-reported cohort and contributor figures, not an official NSE publication, and they describe that quarter rather than a permanent earnings pattern.

No. Earnings leadership depends on the period, the metric, and whether the comparison includes Nifty 50 itself. In Q1 FY26, Nifty 50’s median PAT growth exceeded the Nifty 500 median, while Nifty 500 aggregate growth exceeded both Nifty 50 and Nifty 500 excluding Nifty 50. FY26 aggregate figures and FY17–FY26 CAGRs tell a different story.

For a sound comparison, identify the reporting period, whether the statistic is aggregate or median, and whether the broader index includes Nifty 50. Also keep earnings growth separate from index returns: index performance reflects share prices and dividends as well as the underlying earnings measures, and the figures above do not establish that market-cap weighting by itself caused a return difference.
Quick Recap
How to read the next earnings comparison
- Check the universe: Nifty 500 includes Nifty 50; Nifty 500 ex-Nifty 50 does not.
- Check the measure: aggregate PAT, median PAT, EPS, profit share, and market-cap coverage are not interchangeable.
- Check the period: a quarter, a fiscal year, and a multi-year CAGR can yield different leaders.
- Check the composition: sector exposure and constituent mix may help explain a gap, but do not establish its cause on their own.
