Stock Exchange is a marketplace, wherein the trading of securities between buyers and sellers takes place. The two largest and famous stock exchanges of India are the Bombay Stock Exchange (BSE) and National Stock Exchange (NSE). Sensex is a flagship index of BSE, whereas Nifty is a main index of NSE.
Nifty and Sensex are basically market indices, which serve as a benchmark to indicate a market trend, development in the industry, and the portfolio of the individual investor.
What is Index?
To measure the country’s economic development, the financial performance of the share market acts as a parameter. However, there are many companies listed on the stock exchange and to know the market’s performance, one cannot track the stocks of all the companies. In this way, a sample is chosen to represent the movement of the entire market, and that small sample is called Index.
The index reflects the economic growth of the companies and the country as well. It is basically a sample of a certain number of companies, which are the best and biggest according to free-float market capitalization. Considering the direction of the sample companies, a general opinion can be made, regarding the market trend for the day.
Further, the reasons for up and down movement of the index may include a change in government policy, or change in government, forecasting of good weather, international affairs, industry future, etc.
Therefore, Nifty and Sensex are like exit polls, which helps in determining the overall market trend using the index as a sample.
When the arrow in Nifty and Sensex, appears green in color it signifies that the trading is done at a higher price, as compared to the closing value of the previous trading day, whereas when the arrow appears red it indicates that the trading is done at a lower price, than the closing value of the previous trading day.

Frequently Asked Questions (FAQs)
Do companies listed in BSE can also be listed in NSE?
The stocks of a company can be listed in both the stock exchanges. And in both the exchanges the stock prices may differ, as the prices depend on the number of buyers and sellers. Further, such companies are called dual listed. It helps in increasing the company’s access to capital and brings more liquidity.
What happens if the stocks of a certain company are continuously performing badly?
When the stocks of a certain company are performing badly, for a long time, then the stock exchange replaces the stocks of that company with some other company that is well established and whose stocks are performing well in the market.
How the companies in indices are selected?
The companies in indices are selected on the basis of free-float market capitalization, that includes companies from all the sector.
What is Free float market capitalization?
When a company offers shares to the public for sale, it never offers 100% shares. This is due to the fact that the owner always keeps the majority shares to keep the decision-making power with himself. It is considered an ideal method to calculate equity indices.
Free-float market capitalization means market capitalization of the index’s underlying companies, which considers only those stocks that are readily available for sale to the general public in the market. This means that unlike a full market capitalization wherein both active and inactive shares are considered, in a free-float market capitalization, shares owned by the company’s management are not taken into account.
Categories Excluded from the Calculation of Free Float Market Capitalization
- Shares held by promoter or group of promoters
- Government holding being a strategic investor
- Shares held by promoters by way of ADR or GDR.
- Strategic stakes by corporate bodies (only to the extent to which it is identifiable)
- Employee Welfare Trusts
- Investments under the FDI category
- Shares under the lock-in category
- Equity that associate or group companies (cross-holdings) held.
What is Investible Weight Factor?
