Shares of InterGlobe Aviation, the parent company of IndiGo, climbed nearly 2% on November 24 after the BSE announced that the airline’s stock will be added to the benchmark 30-share Sensex starting December 22.

Tata Motors PV Drops 1.5% on Sensex Exit Sensex Rejig Details: Who’s In and Who’s Out BSE Bankex Also Sees Additions Market Reaction and Outlook

In early Monday trade, IndiGo shares surged to Rs 5,953, reflecting immediate investor enthusiasm.
The stock currently carries a market capitalisation of Rs 2.27 lakh crore, and a standalone P/E ratio of nearly 45, underscoring its growth trajectory and strong market positioning.

IndiGo shares have gained 9% in the past six months and over 28% so far in 2025, making it one of the best-performing aviation stocks in the country this year.

Tata Motors PV Drops 1.5% on Sensex Exit

The Sensex reshuffle brought a contrasting reaction for Tata Motors Passenger Vehicles (PV).
Following news of its exclusion from the benchmark index, the newly listed stock fell more than 1.5%, sliding to a low of Rs 356.65 apiece.

Tata Motors PV currently holds a market capitalisation of Rs 1.32 lakh crore and trades at a P/E ratio of more than 1.4.
The drop reflects the typical investor behaviour seen during index exit announcements, as institutional flows often shift away from stocks leaving major indices.

Sensex Rejig Details: Who’s In and Who’s Out

The update to the BSE indices includes multiple changes across key benchmarks.
IndiGo will replace Tata Motors PV on the Sensex, becoming part of India’s most tracked equity index starting December 22.

In addition to joining the Sensex, the BSE stated that IndiGo will also replace the PV-maker on the BSE Sensex 50, while Tata Motors PV will shift to the BSE Sensex Next 50.
“These changes will take effect from December 22 onwards,” the exchange said in its notice.

Another notable change comes to the broader indices:

IDFC First Bank will replace Adani Green Energy on the BSE 100,
Adani Green Energy will move to the BSE Sensex Next 50, taking the slot vacated by IDFC First Bank.

These reshuffles are expected to influence passive fund flows, as index-tracking funds rebalance their portfolios.

BSE Bankex Also Sees Additions

Beyond the Sensex and broader indices, the BSE Bankex will undergo changes as well. Starting December 26, four new stocks will be added to the index:

Canara Bank
AU Small Finance Bank
Punjab National Bank (PNB)
Union Bank of India

The adjustments aim to better reflect evolving market dynamics and the rising importance of public sector and private sector banks.

Market Reaction and Outlook

Investors welcomed IndiGo’s inclusion in the Sensex, seeing it as a recognition of the airline’s sustained growth and strong fundamentals.
Being part of the benchmark index often boosts liquidity, visibility, and institutional participation for a stock.

On the other hand, Tata Motors PV’s decline reflects short-term sentiment pressure typically associated with index exclusion. Newly listed stocks often face volatility during reshuffles, particularly when shifting between large-cap index categories.

With the changes scheduled to take effect in late December, analysts expect increased volatility and rebalancing activity in the coming weeks as both active and passive funds adjust their holdings.
