How Is The Nifty Index Calculated? An Overview

When we use the term Indian stock market, we are all talking about either the Nifty or Sensex. Nifty and Sensex consist of India’s largest and finest companies with good fundamentals. These companies have a huge role in the growth of the economy of the country. The market index acts as a barometer for gauging the long-term health of the Indian economy. 

Many times you have heard the news anchor saying "Nifty has gained 50 points today or Nifty is 100 points down today." so, what does it mean? In this article, we are going to learn about what Nifty is, the Nifty calculation formula, the process of Nifty calculation, and how Nifty 50 is calculated. 

What Is Nifty? 

Before understanding the Nifty, it is important to understand the market index. A market index consists of stocks that are created by the stock exchanges. The index was introduced in 1992. The leading two stock indices in the stock market: Nifty and Sensex 

The index of NSE (National Stock Exchange) is Nifty and the index of BSE (Bombay stock exchange) is Sensex. 

Nifty has market cap indices such as Nifty small cap, nifty mid-cap, and nifty large-cap as well as sectoral indices such as Nifty IT, Nifty bank, and Nifty pharma. Nifty has a well-defined and transparent methodology to select companies. It is selected on 4 aspects: The universe of companies, the basic construct, the liquidity, and the rebalancing and reconstruction rules.

Nifty 50 consists of the top 50 companies belonging to different sectors. The term Nifty 50 is a short form of National stock exchange 50 but now it has been shortened to Nifty 50. The top 50 companies that are listed on the Nifty 50 should be listed on the NSE. Also, the nifty carries representation from 13 different sectors including Financial Services, IT, Oil and gas, Consumer goods, Automobile, Metals, Pharma, Construction, Cement & cement production, Telecom, power, services, and fertilizer & pesticides. These companies are market leaders in their sector and have large market capitalization. It represents the overall performance of the share market and is used by various investors including retail investors, domestic investors, institutional investors, and foreign investors to gauge the market performance. 

Eligibility Criteria to be the Constituents of Nifty 50

  •  The company must be listed on the stock exchange. 
  • The company should be available for trading in the Future & Options segment on NSE. 
  • The selected companies have to be in the top 50 companies in terms of their free-float market capitalization. Free float means shares that are publicly traded.
  • The company should have high liquidity. Liquidity means that the trading volume of the stock should be always high. 
  • On a semi-annual basis, the rebalancing exercise of nIfty is done which determines which stocks stay within the Nifty, which new ones come in, and which of the existing companies move out of the Nifty. This process happens in June and December of every year. 

The importance of nifty’s in the financial markets allows for a lot of innovation around it. For instance, mutual fund managers use Nifty as a benchmark. For example, the Nifty 50 index has given a 15% return in the last year but your mutual fund has given a 12% return. In this case, you are at a loss of 3% and the index is performing better than a mutual fund. On the other hand, if the mutual fund has given an 18% return in the last year, here you have beaten the market.

  • The fund manager doesn't need to research stocks or balance them periodically. All they have to do is track and invest directly in stocks that are constituents of the Nifty 50.

How Nifty Index Is Calculated?

The method that is used to gauge the nifty index is the Float-adjusted and Market Capitalization method. This method represents the overall market value of all the Nifty 50 stocks relative to the base period. The base year taken for the calculation of nifty is November 3, 1995. 

  1. The first step for the Nifty 50 calculation is to calculate the market capitalization of all the nifty 50 companies. It reflects the overall value of all the shares of a company held by various traders in the market. Market capitalization is calculated by multiplying the number of shares outstanding by their current market price.
  2. The next step is to multiply the market capitalization of all the nifty 50 companies with the (IWF) investable weight factor. The Investable weight factor helps to find the shares available for trading. However, it does not include the shares held by promoters of the company, employees, and the government. 
  3. Then the weighted free float market cap is calculated by multiplying market cap with IWF and weight.
  4. The last step is to calculate the index value by dividing the current market value by the base market capital and then the result is multiplied with 1000. The base year taken to calculate the index value is 1995.
