NIFTY 50 index is the National Stock Exchange of India's benchmark broad-based stock market index for the Indian equity market. It represents the weighted average of 50 Indian company stocks in 13 sectors and is one of the two main stock indices used in India, the other being the BSE Sensex.

NIFTY 50 is computed using a free-float market capitalization-weighted method, wherein the level of the index reflects the total market value of all the stocks in the index relative to a particular base period. The index is calculated in real-time daily whenever the value of any scrip changes.

There are many stock exchanges available over the world, that facilitate trading and other similar functions as NSE and BSE, but Indian market majorly relies on these two stock markets.
