Sensex Rejig: IndiGo To Replace Tata Motors PV In Benchmark Index From December 22

InterGlobe Aviation, the parent company of IndiGo and India’s largest airline, is set to join the BSE Sensex from December 22, 2025. The inclusion was announced by BSE Index Services, a BSE subsidiary, as part of its semi-annual index review. The Sensex tracks 30 of the most valuable and actively traded companies on the BSE.

InterGlobe Aviation will be replacing Tata Motors Passenger Vehicles on the 30-stock benchmark index. This inclusion will place the airline operator among the most valuable and liquid companies on the exchange. Earlier this month, Tata Motors completed its demerger into two entities: Tata Motors Passenger Vehicles (TMPV) and Tata Motors Commercial Vehicles (TMCV).

Among other BSE indices, IDFC First Bank will be included in BSE 100, replacing Adani Green Energy. BSE Sensex 50 will see the inclusion of Max Healthcare Institute and exclusion of IndusInd Bank.

IndusInd Bank will move to BSE Sensex Next 50, along with IDFC First Bank.

BSE Bankex, which tracks the 10 most valuable and liquid banking stocks, will see new addition of four stocks, including Canara Bank, AU Small Finance Bank, Punjab National Bank and Union Bank of India.

Why BSE Index Services Rejigs Indices

BSE Index Services’ Index Oversight Committee meets every quarter to assess whether its indices need any changes, according to the BSE Indices Methodology document. The committee reviews corporate actions that may affect existing constituents, checks whether the indices still mirror broader market conditions, considers potential companies for inclusion, and takes note of major market developments that may call for adjustments.

BSE says it updates its indices to keep them accurate and aligned with current market trends. Companies that no longer meet the required norms for size, liquidity or trading activity are removed, while stronger candidates are added. The methodology document also notes that maintaining clear and well-structured indices is important because many domestic and global funds track them. Regular rebalancing ensures the indices continue to serve as reliable benchmarks for passive and institutional investors.
