What is Nifty 50?

The Nifty 50 is a broad-market index launched by the National Stock Exchange (NSE) on April 22, 1996.

Most of the constituents of the Nifty50 are highly liquid blue chip companies with mature businesses, high market capitalisations and strong financials.

Things to Know About the Nifty50

Now that you’re aware of what the Nifty 50 index is, let’s look at a few things you need to know about the broad-market index.

    The Nifty50 index is reviewed regularly on a semi-annual basis, i.e. twice every year. The cut-off date for the review is the 31st of January and 31st of July.

    If any company doesn’t meet the necessary requirements, it is removed from the index. Furthermore, the governing bodies also examine the data of all of the companies listed in the NSE to determine if any company meets the eligibility criteria to be included in the index. The companies that meet the criteria are included in place of those removed from the index.
