MSCI Inc. said it will add 42 securities and remove 56 from its flagship All Country World Index when the provider’s quarterly review takes effect after the market close on 26 August. The shake-up is part of the August 2025 index rebalancing that guides tens of trillions of dollars in passive and active funds linked to MSCI benchmarks. Rocket Lab, SoFi Technologies and Affirm Holdings are the largest companies by market value moving into the developed-markets segment of the ACWI. Their inclusion could draw additional passive inflows from managers who replicate the benchmark. Within the Emerging Markets Index, China CITIC Bank, Indonesia’s Dian Swastatika Sentosa and Hong Kong-listed Laopu Gold head the list of new entrants. MSCI said China, Taiwan, India and South Korea together still account for more than three-quarters of the gauge’s weight, with China leading at 29.2 percent as of 31 July. The review also reshuffles MSCI’s country sub-indexes. In India, Vishal Mega Mart, food-delivery platform Swiggy, solar kit maker Waaree Energies and Hitachi Energy India will join the MSCI India index, potentially improving their visibility with global investors. MSCI’s indexes underpin about $17 trillion in assets worldwide, including roughly $2 trillion in equity ETFs. Index changes can therefore trigger significant portfolio adjustments as investors align with the new compositions.
