If you want to understand how some of India’s large listed companies are performing, the Nifty 100 Index can be a useful benchmark to look at. It includes 100 major companies selected from the Nifty 500 and represents several important sectors of the economy.
In simple terms, the Nifty 100 brings together the companies from two indices: Nifty 50 and Nifty Next 50. This means it gives a broader view of the large cap segment than the Nifty 50 alone. Investors, fund managers, and passive investment products such as index funds and ETFs often use this index to track the performance of a wide group of large Indian businesses across sectors.

What is Nifty 100?
The Nifty 100 Index is an equity market index that represents 100 large companies selected from the Nifty 500. In simple terms, it helps you track how some of India’s large listed companies are performing in the stock market.
The index combines the companies from two well-known indices: Nifty 50 and Nifty Next 50. This means it gives a wider view of the large cap segment than the Nifty 50 alone. While the Nifty 50 covers 50 large companies, the Nifty 100 includes these companies along with the next set of large companies from the Nifty Next 50 universe.
The Nifty 100 is calculated using the free-float market capitalisation method. This means that companies with a higher market value available for public trading usually get a higher weight in the index.
The index is commonly used by investors and fund managers to compare portfolio performance. It can also be used as the underlying index for passive investment products such as index funds and ETFs, subject to tracking error. There are also variants of the index, such as the Nifty 100 Total Returns Index and the Nifty 100 Equal Weight Index.
How does Nifty 100 work?
The Nifty 100 Index consists of 100 large listed companies selected from the Nifty 500. These companies are primarily chosen based on their market capitalisation, which reflects the total market value of the company.
The index follows the free-float market capitalisation methodology. Under this approach, companies with a higher market value of publicly tradable shares carry greater weight in the index. Shares held by promoters or other locked-in investors are excluded from this calculation.
NSE Indices reviews the Nifty 100 twice a year, with cut-off dates of January 31 and July 31. During these reviews, companies may be added or removed based on their market capitalisation ranking, continued inclusion in the Nifty 500, and other eligibility criteria.
To be considered for inclusion, a company must have a minimum listing history of one month as of the cut-off date. NSE Indices provides the market with four weeks’ notice before implementing any changes.
The index is updated periodically to ensure it continues to reflect a broad cross-section of large Indian companies.
Features of Nifty 100
The Nifty 100 Index has a few key features that make it useful for understanding the broader large cap space in India:
Exposure to 100 large companies
The index includes 100 large listed companies, giving investors a wider view of the large cap market than narrower indices.
Covers major sectors
The Nifty 100 includes companies from different sectors of the economy, which helps reduce dependence on any one sector.
Based on free-float market capitalisation
The index gives higher weight to companies with a larger market value of publicly available shares.
Reviewed periodically
NSE Indices reviews and rebalances the index at regular intervals to ensure it continues to represent eligible large listed companies.
Used as a benchmark
The Nifty 100 is often used to compare the performance of mutual funds, portfolios, index funds, and ETFs.
Available through passive investment options
Investors can gain exposure to the Nifty 100 through index funds and ETFs that aim to track the index, subject to expenses and tracking error.
Top constituents of Nifty 100 by weightage
The Nifty 100 Index includes 100 companies, but each company does not have the same weight in the index. Companies with a higher free-float market capitalisation usually carry a larger weight, which means they have a bigger impact on the movement of the index.
| Company name | Weight (%) |
| HDFC Bank Ltd. | 9.14 |
| ICICI Bank Ltd. | 7.37 |
| Reliance Industries Ltd. | 6.54 |
| Bharti Airtel Ltd. | 4.21 |
| Larsen & Toubro Ltd. | 3.63 |
| State Bank of India | 3.17 |
| Axis Bank Ltd. | 2.89 |
| Infosys Ltd. | 2.62 |
| Kotak Mahindra Bank Ltd. | 2.16 |
| ITC Ltd. | 2.07 |
As seen above, financial services companies such as HDFC Bank, ICICI Bank, State Bank of India, Axis Bank, and Kotak Mahindra Bank form a significant part of the top holdings. This means that movements in large banking and financial stocks can influence the performance of the index.
However, these weights are not fixed. They may change over time based on market movements, changes in free-float market capitalisation, and index rebalancing.

Historical returns of Nifty 100 Index
Looking at index returns can help investors understand how the Nifty 100 has performed across different time periods, although past performance does not guarantee future returns:
| Index return type | QTD (%) | YTD (%) | 1 year (%) | 5 years (%) | Since inception (%) |
| Price Return | 8.92 | -6.65 | -4.68 | 14.66 | 9.32 |
| Total Return | 9.39 | -6.1 | -3.64 | 10.54 | 16.25 |
The Price Return reflects only the change in index prices, while the Total Return also considers dividends or income from the index constituents. As seen above, returns can vary across short-term and long-term periods, which is why investors should avoid judging the index based only on recent performance.
