These are the two most popular indices for Indian stock markets and are produced by the Bombay Stock Exchange (BSE) and National Stock Exchange (NSE) respectively.
The Sensex which was first calculated in 1986 is based on the market capitalisation (share price times the number of shares outstanding) of 30 important stocks. The actual stocks have changed over the years along with the Indian economy but in general the Sensex represents the stock prices of the largest and most important companies from a variety of sectors. It is updated every 15 seconds during trading hours.
