The National Stock Exchange (NSE) has included two Adani group firms — Adani Wilmar and Adani Power — in some of its indices.

The changes will be effective from March 31. Adani Wilmar will be part of the Nifty Next 50 and the Nifty 100 indices, while Adani Power will be included in the Nifty 500, Nifty 200, Nifty Midcap 100, Nifty Midcap 150, Nifty LargeMidcap 250, and the Nifty Midsmallcap 400 indices.

However, at the same time, Adani Wilmar will be excluded from the Nifty Midsmallcap 400 index, Nifty Midcap150, and the Nifty Midcap 100.

A late evening statement from the bourse on Friday said these replacements in various indices were made by the index maintenance sub-committee of NSE Indices as part of its periodic review. However, the National Stock Exchange (NSE) did not make any changes to its benchmark Nifty 50 index.

In the Nifty Next 50 index, apart from Adani Wilmar, other companies that will be included are ABB India, Canara Bank, Page Industries and Varun Beverages. The scrips that will be dropped include Bandhan Bank, Biocon, Gland Pharma, MphasiS and One 97 Communications.

This index has 50 stocks with a total market cap of over Rs 38.56 lakh crore. On Friday, the index closed at 38439.40, a drop of 0.62 per cent or 240.70 points.

The Nifty Next 50 Index represents 50 companies from Nifty 100 after excluding the Nifty 50 companies.

Since the release of the Hindenburg Research report, the Adani group firms hadseen more than $100 billionof their market capitalisation being wiped out.

While some ofthe investors have been using the sharp fall in its shares to make bargain purchases, the counters have been witnessing volatile movements in line with news reports. On Friday, Adani Power and Adani Wilmar had finished higher with gains of 4.97per cent and 5 per cent, respectively.

However, three group companies, which included flagship Adani Enterprises, ended in the red after controversial remarks made by billionaire George Soros.

Earlier this week, MSCI Inc postponed the implementation of reducing the weightages of Adani Total Gas and AdaniTransmission, in its indices, citing potential impact from price limit mechanisms.
