The composition of the Nifty 500 index has undergone a significant structural transformation over the past 26 years, reflecting India's evolving economic landscape. According to an NSE report, the index has shifted from a commodity- and manufacturing-heavy universe at the turn of the millennium to one increasingly driven by financial intermediation, services and domestic demand. This transformation highlights the structural transformation of corporate India, with the sector's representation and market capitalisation in financials increasing from 8% of index constituents and 7% of market capitalisation in March 2000 to 20% and 26%, respectively, by March 2026. The financial sector has emerged as the defining growth story, with the sector overtaking energy as the largest contributor to revenues in FY25, ending more than two decades of energy sector leadership.
The financial sector has emerged as the defining growth story, with the sector overtaking energy as the largest contributor to revenues in FY25, ending more than two decades of energy sector leadership. As reported by NSE, traditional sectors such as materials and consumer staples gradually ceded ground, while healthcare, utilities, and consumer discretionary gained prominence, reflecting rising incomes, urbanisation and greater formalisation of the economy. Meanwhile, the earnings growth of Nifty 500 has outpaced its revenue expansion during the past 26 years, with aggregate net sales increasing 21-fold between FY03 and FY26 while PAT rose 31-fold. The sector's leadership is further reinforced by the Nifty Financial Services index, which represents the broader financial services sector including banks, insurance companies, NBFCs and other financial institutions.
The NSE report reveals significant broadening of corporate performance beyond heavyweight companies in the Nifty 50 index. The Nifty 50's share of aggregate Nifty 500 profits fell sharply from 87% in FY18 to 51% in FY26, while the broader universe delivered a superior PAT CAGR of 16.9% during FY17–FY26 versus 12.5% for the Nifty 50. The aggregate PAT margin improved from 6% in FY00 to 10.9% in FY26, reflecting sustained improvements in operating efficiency and profitability across business cycles. In FY26, aggregate profit at Nifty 500 companies grew 15.4%, outpacing the Nifty 50's 9.1% increase*, with companies outside the Nifty 50 generating roughly two-thirds of the incremental profit growth. The Nifty Next 50 contributed 4.4 percentage points, Nifty Midcap 150 added 4.5 points, and Nifty Smallcap 250 contributed another 1.4 points to the broader index's approximately 15% profit growth.
The expansion was equally visible across the market-cap spectrum, with the thresholds for large- and mid-cap classification rising 122-fold and 180-fold, respectively, underscoring both the growing scale of listed companies and continued mobility across the broader market. According to the NSE report, concentration in EBITDA and PAT fell from 46 to 20 and from 225 to 80, respectively, indicating that earnings growth has become increasingly broad-based. The shift is also visible in valuations as the Nifty 50 now accounts for just 40.5% of NSE-listed market capitalisation, down from 62.3% in FY14, signalling that India's wealth creation engine is moving beyond its biggest corporate heavyweights to mid and smaller sized companies. The number of entities listed on the NSE increased from 422 in FY96 to 3,005 by June 2026, giving investors access to a much larger set of companies across sectors and market-cap segments.
The divergence between large-cap and broader market performance has become more pronounced in 2026, with Nifty 50 companies' market capitalisation down 7.6% for the year through June, while mid-cap, small-cap and micro-cap companies recorded increases of 10.7%, 14.3% and 19.5%, respectively. The overall concentration of market capitalisation across NSE-listed companies consequently dropped to a multi-year low, with the market-wide Herfindahl-Hirschman Index falling to 67 in June 2026, compared with 173 in March 2020. For investors, the data challenge the assumption that India's earnings story can be captured through the Nifty 50 alone, with almost half of Nifty 500 profits now generated outside the benchmark. As per Trideep Bhattacharya, chief investment officer at Edelweiss Mutual Fund, the data supports a flexi-cap strategy over large-cap, as some mid-cap companies are emerging as challengers to incumbent business models that dominate the large-cap universe.
