IndiGo is set to join the Sensex in December as Tata Motors’ PV arm makes way

The parent company of India’s largest carrier, InterGlobe Aviation, operator of Indigo Airlines, Tata Motors Passenger Vehicles will open in the 30-stock Sensex benchmark on Monday, December 22. The exchange index administrator, BSE Index Services, announced the changes on Saturday. Indicators

Along with the change in the Sensex, a series of adjustments in other major indices will follow.

In the BSE 100 index, IDFC First Bank Ltd will be included, Adani Green Energy Ltd will be replaced within the BSE Sensex 50, Max Healthcare Institute Ltd will be added, while IndusInd Bank Ltd will be removed.

Meanwhile, in the BSE Sensex Next 50 index, IndusInd Bank and IDFC First Bank will replace Max Healthcare Institute Ltd and Adani Green Energy, the announcement said.

The Sensex inclusion of InterGlobe Aviation reflects its growing market prominence, while Tata Motors exits the PV following its separation from Tata Motors after the recent demerger. The corporate restructuring repositioned Tata Motors within the passenger vehicles benchmark, paving the way for the entry of InterGlobe Aviation.

Such rebalancing helps ensure that the index is representative of India’s evolving market landscape. The change will also prompt a mandatory reallocation by index-tracking funds and exchange-traded funds that mirror the Sensex and related BSE indices, triggering mechanical buying and selling as portfolios realign with the new composition.

The December 22 reshuffle marks a significant transition in India’s equity benchmark, with aviation replacing automobiles, and corporate restructuring making room for new market leadership at Dalal Street’s top table.
