Ahead of the exclusion, shares of IDFC fell 0.45 per cent to Rs 153.05 on NSE today.
The changes will come into effect from tomorrow, in line with the announcement made late last month by India Index Services & Products Ltd (IISL), an NSE group firm that manages Nifty and other indices.
A host of modifications will also be introduced by its Index Maintenance Sub-Committee in various other NSE indices such as CNX Nifty Junior, CNX 100, CNX 200, CNX 500 and CNX Service Sector during a periodic review.
Those being dropped from CNX 200 include Adani Enterprises and IDFC while Alstom T&D India and City Union Bank will get in.
