MSCI Announces November Equity Index Changes Including Addition of Moderna to World Index
MSCI has released its November 2026 Equity Index Review, detailing upcoming adjustments across its U.S. equity indexes. The most significant change is the inclusion of Moderna (MRNA) into the MSCI World Index, a move that typically triggers institutional rebalancing as passive funds tracking the index must adjust their holdings. In addition to Moderna, Canada's Aritzia will also be added to the index suite. These changes are scheduled to take effect following the market close on November 30, 2026, impacting liquidity and trading volumes for the affected securities as index-tracking funds align with the new compositions.
