Nifty 100

The Nifty 100 is a broad large-cap equity index maintained by NSE Indices Limited that comprises the 100 largest companies by free-float market capitalisation listed on the National Stock Exchange — effectively combining the Nifty 50 (India's premier large-cap index) and the Nifty Next 50 (the next tier of large-cap companies) into a single index providing comprehensive large-cap market coverage. The Nifty 100 is constructed using the free-float market capitalisation weighting methodology and is reviewed semi-annually. With approximately 75% to 80% coverage of total NSE market capitalisation, the Nifty 100 provides investors with broader diversification than the Nifty 50 alone — capturing an additional 50 large-cap companies across sectors including capital goods, real estate, infrastructure, specialty chemicals, and consumer services that may not be included in the flagship Nifty 50. The index serves as the basis for Nifty 100 index funds and ETFs, allowing investors to access the full large-cap spectrum of the Indian equity market through a single passive instrument. The Nifty 100's performance closely tracks the Nifty 50 due to the heavy weightage of top-50 companies in the free-float cap-weighted methodology, but provides marginally broader sectoral exposure and reduced concentration risk by including the second tier of large-cap leaders that form the foundation of India's established corporate sector
