Overview of the Nifty 50 index, its calculation methodology, and its role within India’s equity market framework.
Last updated on: March 06, 2026
The Nifty 50 is one of the primary equity indices maintained by the National Stock Exchange (NSE). It represents the free-float market capitalisation–weighted performance of 50 large and liquid companies listed on the NSE across diverse sectors. The index is widely referenced in market analysis and serves as a commonly used performance indicator within India’s equity markets.
The Nifty 50 is a market-capitalisation-weighted index comprising 50 large-cap companies listed on the National Stock Exchange (NSE). It tracks the collective performance of these companies based on their free-float market capitalisation, meaning only publicly available shares are considered in weight calculations. The index is reviewed semi-annually by NSE Indices to ensure continued compliance with eligibility criteria related to liquidity, market capitalisation, and trading frequency.
The Nifty 50 is calculated using the free-float market capitalisation-weighted methodology. Each constituent’s weight is proportional to its free-float market value relative to the total free-float market capitalisation of all index constituents.
Index Value = (Current Free-Float Market Capitalisation / Base Market Capitalisation) × Base Index Value
Base date: 3 November 1995
Base index value: 1000
Rebalancing: Conducted semi-annually
This methodology assigns higher index weight to companies with larger free-float market capitalisation.
Companies included in the Nifty 50 must satisfy eligibility conditions defined by NSE Indices.

The Nifty 50 comprises large-cap companies across sectors such as financial services, information technology, energy, consumer goods, and telecommunications.

Nifty 50 index funds are structured to mirror the composition and weighting of the Nifty 50 Index. As passively managed instruments, their portfolio allocation aligns with index constituents rather than active stock selection. Their structure and cost framework differ from actively managed equity funds, and their performance is linked to movements in the underlying benchmark.
Nifty 50 index funds are passively managed schemes designed to replicate the index composition. Their structure typically involves lower portfolio turnover compared to actively managed funds. Performance is intended to track index movement, subject to tracking error and expense ratios.

1995: Base date established (3 November 1995)
