By | October 18, 2020


Though there are quite a few stock exchanges in India, most of the trading takes place on the Bombay Stock Exchange (BSE) and the National Stock Exchange (NSE). Most of the notable companies in the country are listed on these two stock exchanges. Sensex (Sensitive Index) and NIFTY are the two well-known market indices in the Indian stock market. While Sensex is associated with BSE, NIFTY is associated with NSE.

A little about BSE and NSE

BSE came into existence in 1875 and it is the 11th largest stock exchange in the world. NSE was launched in 1992. However, it started trading only in 1994. They function similarly, whether it is their trading mechanism, the settlement cycle, or the trading hours.

What is a stock market?

In simple terms, a stock market is basically a place where trading of stocks, futures, bonds, etc. takes place. By trading, we mean buying and selling. It consists of the primary market and the secondary market.

In a primary market, stocks are bought directly from the company issuing them. Companies are allowed to sell stocks only after they conduct an IPO (Initial Public Offering). In a secondary market, the stock trading happens between buyers and sellers without any involvement from the company. Anyone can buy stocks from the secondary market as long as they can pay the price of the trade.

What is a market index?

An integral part of stock markets, market index is the term applied to the summary of the market prices. For your convenience, all the chaos in the markets is summed up in a single number. This conveys the market performance in comparison with the previous performances. The performance of an index depends on how well its stocks perform. Sensex and NIFTY are two such market indices that are vital to the Indian stock market.
