Market Response to the Proclamation
Initial market reaction on Monday morning reflected the anticipated changes. InterGlobe Aviation shares experienced a slight uptick, trading at Rs 6,092.50, a gain of Rs 6.00 or 0.10 percent. Max Healthcare, however, saw a marginal decline, closing at Rs 1,216.70, down 1.46 percent.

Free-Float Market Capitalisation Drives the Shift
The NSE’s decision is based on a review of average free-float market capitalisation over the preceding six-month periods concluding in January and July. IndiGo’s considerable free-float, reported at rs 1.14 lakh crore, and Max Healthcare’s Rs 84,555 crore, were key factors in their inclusion. In comparison, IndusInd Bank and Hero MotoCorp had average free-float market capitalisations of Rs 55,270 crore and Rs 52,336 crore respectively.

Performance Review: Key Stocks
IndiGo has demonstrated strong investor returns throughout 2025, with a year-to-date increase exceeding 32 percent. This surge highlights the airline’s resilience and growth potential amidst a recovering aviation sector. Meanwhile, IndusInd Bank has faced challenges, experiencing a 17.59 percent decline through July, largely attributed to a USD 230 million loss stemming from derivative misaccounting and the subsequent resignation of key executives. Hero MotoCorp, in contrast, has achieved a more moderate year-to-date gain of 1.82 percent.
| Company | Index Change | YTD Performance (2025) | Free-Float Market Cap (INR Crore) |
|---|---|---|---|
| InterGlobe aviation (IndiGo) | Added to nifty 50 | +32% | 1.14 Lakh |

| IndusInd Bank | Removed from Nifty 50 | -17.59% | 55,270 |

The NSE also announced adjustments to the Nifty 100, Nifty Next 50, Nifty 500, Nifty Midcap, and Nifty Smallcap indices, even though no changes were made to specialized sectoral indices like Nifty Bank, Nifty IT, FMCG, Oil & Gas, or Metals.

Volatility: Assessing price fluctuations to maintain index stability.
Trading Frequency: How often shares are traded.
These factors are weighted, and the review happens semi-annually, typically in June and December. Changes are announced a month prior to implementation. The upcoming review in December 2025 is expected to reflect these shifts.
