Over 2,000 companies are listed on the NSE (National Stock Exchange). In such a case, if you have to find out how the stock market is moving, you can’t go ahead and check every company’s performance, right?  

Instead, a more feasible option would be to check the overall trends of the industry or sector and market sentiment towards the same. Here, sector means an area of the economy where businesses have the same or related business (activity, product, or service). 

Key Takeaways 

  • NSE Sectoral Indices classify companies by industry, allowing investors to easily track sector-specific market movements. 

  • These indices serve as economic indicators, providing a clear picture of how various sectors are functioning without relying on individual companies. 

  • Eligibility requirements for inclusion in a sectoral index include NIFTY 500 membership and free float market capitalisation. 

  • ETFs and Index Mutual Funds provide retail investors with tailored sector exposure. 

What Is a Stock Market Index? 

Indices are economic indicators that give us a sense of whether the economy is performing well or not. And a stock market index reflects the changes taking place in the market. Similar listed stocks from the same sector are grouped together to create an index. Popular benchmark indices in India are NIFTY (NSE) and SENSEX (BSE), while benchmark indices are NIFTY 50 and BSE 100. These stock market indices help you in:  

  • Monitoring the market’s pattern 

  • Identifying trends in an industry 

  • Taking investment decisions 

  • Understanding the direction of the economy 

What Do You Mean by Sectoral Indices? 

The NSE oversees whether the clearing members and the listed companies are abiding by the rules and regulations implemented by SEBI and the exchange. NSE Indices Limited, a subsidiary of NSE, provides these indices and index-related services for the capital market. The company is responsible for the NIFTY indices of NSE. It consists of broad-based indices, thematic indices, sectoral indices, customized indices and strategy indices. 

The sectoral indices represent specific sectors and give benchmarking data of those sectors in the market. For the purpose of sectoral indices, various sectors identified are energy, healthcare, automobile, consumer products, IT, telecom, and financial. Let’s understand this with an example - Bank NIFTY in NSE's sectoral indices represents the overall performance of the Indian banking sector. Sectoral indices are reviewed on a semi-annual basis, ending in January and July.
