List of NIFTY 100 Index Stocks 

What is the NIFTY 100 Index?

The NIFTY 100 is a diversified index that includes the 100 largest companies in India based on full market capitalisation. It is essentially a combination of two other major indices: the NIFTY 50 and the NIFTY Next 50. This structure allows the index to provide a comprehensive view of the large-cap segment of the Indian equity market.

The primary objective of the NIFTY 100 is to measure the performance of these large, well-established companies. The index is calculated using a free-float market capitalization method, which means the value of the index is determined by the market price of the shares multiplied by the number of shares available for public trading. This method ensures that the index accurately reflects the market's sentiment and the real value available to investors.
