Compliance Requirements

  • Passive funds and ETFs tracking these indices must rebalance their portfolios to reflect the new composition

  • Disclosure requirements as per fund mandates may apply

Important Dates

  • December 22, 2025: Effective date for all index reconstitution changes

Impact Assessment

Market Impact:

  • Stocks being added to indices may see buying pressure from passive funds, potentially increasing prices and liquidity
  • Stocks being removed may face selling pressure as index funds divest holdings
  • Highest impact expected on stocks moving in/out of BSE India 150 and BSE 100 Largecap TMC due to larger fund tracking

Trading Impact:

  • Increased trading volumes expected around December 22, 2025 for affected stocks
  • Potential volatility in affected securities during rebalancing period

Investor Considerations:

  • Passive investors in index funds/ETFs will automatically see portfolio changes
  • Active investors may anticipate rebalancing flows for tactical positioning

Impact Justification

Index reconstitution affects passive fund rebalancing and stock liquidity but is a routine periodic event. Medium impact on affected stocks due to potential fund flows.
