Nifty has market cap indices such as Nifty small cap, nifty mid-cap, and nifty large-cap as well as sectoral indices such as Nifty IT, Nifty bank, and Nifty pharma. Nifty has a well-defined and transparent methodology to select companies. It is selected on 4 aspects: The universe of companies, the basic construct, the liquidity, and the rebalancing and reconstruction rules.

Nifty 50 consists of the top 50 companies belonging to different sectors. The term Nifty 50 is a short form of National stock exchange 50 but now it has been shortened to Nifty 50. The top 50 companies that are listed on the Nifty 50 should be listed on the NSE. Also, the nifty carries representation from 13 different sectors including Financial Services, IT, Oil and gas, Consumer goods, Automobile, Metals, Pharma, Construction, Cement & cement production, Telecom, power, services, and fertilizer & pesticides. These companies are market leaders in their sector and have large market capitalization.
