The term CNX Nifty refers to a regional stock market index found on the National Stock Exchange (NSE) of India. The index is composed of 50 of the largest and most liquid stocks found on the exchange.
The Nifty 50, as it is commonly known, is used to represent the market for benchmarking Indian investments, among other reasons.

 Similar to other major stock indexes such as the S&P 500, companies must meet market capitalization and liquidity requirements before they may be included in the index.
