Sensex & Nifty

The Sensex is an "index". that is an indicator. It gives you a general idea about whether most of the stocks have gone up or most of the stocks have gone down.

The Sensex (SENSITIVITY INDEX) is an indicator of all the major companies of the BSE(Bombay Stock Exchange).Sensex consists of the 30 largest and most actively traded stocks, representative of various sectors.

The Nifty (NATIONAL FIFTY) is an indicator of all the major companies of the NSE(National Stock Exchange). Nifty consists of 50 stocks ie. it has 50 listed companies.

If the Sensex goes up, it means that the prices of the stocks of most of the major companies on the BSE have gone up. If the Sensex goes down, this tells you that the stock price of most of the major stocks on the BSE have gone down.

Just like the Sensex represents the top stocks of the BSE, the Nifty represents the top stocks of the NSE.

The BSE is situated at Bombay and the NSE is situated at Delhi. These are the major stock exchanges in the country. There are other stock exchanges like the Calcutta Stock Exchange etc. but they are not as popular as the BSE and the NSE.Most of the stock trading in the country is done though the BSE & the NSE.
