The Sensex and the Nifty are the two national stock market indices in India. 

The Sensex and Nifty are essential measurements and data that stock traders use to determine market trends daily. But what exactly is the Sensex or the Nifty?

What exactly is an Index?

As per the latest SEBI data, there are over 8600 companies listed on NSE & BSE.

Market experts won’t be able to calculate the performance of each listed stock to determine the market trend. That would be time-consuming and impracticable. Moreover, market trends would have altered by the time the calculation was completed.

So, how can anyone decide on the spur of the moment? With the use of an Index value.

An index selects a representative sample of publicly traded companies from their respective industries. It’s like selecting a few eggs from the basket rather than the entire batch because that would be sufficient to determine whether the eggs are generally decent. 

The Index is a sample of publicly traded companies, and the companies that make up the sample are known as index components.

Stocks in the Index are chosen from all key sectors, rather than just one. When evaluating performance, we look at the bigger picture rather than a single industry in the stock market.

What is the difference between the Sensex and the Nifty?

The Bombay Stock Exchange and the National Stock Exchange are the two stock exchanges in India. 

Each stock exchange needs an index that measures the market’s performance. 

Sensex is the Index for Bombay Stock Exchange (BSE), and Nifty is the Index for National Stock Exchange (NSE).

What is Sensex?

The Sensex, commonly known as the BSE 30, is a market index consisting of 30 well-known and financially stable companies registered on the Bombay Stock Exchange (BSE).

  • An “Index Committee” selects and reviews the 30 companies that make up the Sensex regularly.
  • Academicians, mutual fund managers, finance journalists, independent governing board members, and other financial market participants commonly make up the “Index Committee.”
  • Trading frequency, market capitalization, listing history, industry to which the stock belongs, and other characteristics are used to choose the firms.

If the Sensex falls, it means that the stock prices of most of the BSE’s big stocks have dipped as well. If the Sensex rises, it indicates that most of the BSE’s major stocks gained during the period.

Assume the Sensex is currently at 57,130. If the Sensex falls to 56,600 tomorrow, it signals that the majority of the 30 companies are underperforming, or their stock prices are declining.

What is Nifty?

In contrast to Sensex, Nifty gathers a sample of 50 performing and appealing stocks (Also known as NIfty50) to identify market trends.

Nifty, like the Sensex, selects equities from many industries. The top 50 stocks (Nifty50) are selected from a variety of industries, including information technology, financial services (Niftybank), consumer products, telecommunications, and cars.

Companies must meet the following standards and criteria to be considered for inclusion in the Nifty 50:


The stock should have traded at a cost of 0.50 percent or less over the last six months.

Float Adjustment

The company’s market capitalization must be at least twice the current smallest index composition when adjusted for float.


The company should be based in India and listed on the NSE.
