June 27, 2025 – Global index provider FTSE Russell celebrated the conclusion of its 37th annual Russell Reconstitution at the close of today’s US markets, setting another record for shares traded across Nasdaq as Apple (AAPL) officially reclaims the largest company position from Microsoft (MSFT) in the Russell 3000 and large cap Russell 1000 Indexes, a position it last held from 2021-2023.
The Russell Reconstitution rebalances the entire Russell US Indexes family to maintain an accurate representation of US equity markets and reflect the dynamic US economy. Typically culminating in one of the highest trading volume days of the year, today’s markets closed with $217.20 billion traded across Nasdaq and NYSE – $102.5 billion and $114.7 billion in US stocks traded on the Nasdaq and NYSE, respectively.
For 41 years, the Russell US Indexes have been widely used by investment managers and institutional investors for index funds and as benchmarks for active investment strategies. As of June 30, 2024, approximately $10.6 trillion in investor assets are benchmarked to or invested in products based on the Russell US Indexes.
Fiona Bassett, CEO, FTSE Russell:
“Russell Reconstitution is a cornerstone event for the US equity markets, ensuring the full suite of Russell US Indexes remain precise and representative of the ever-evolving marketplace. This year’s Nasdaq record trading volume underscores the continued trust the investment community places in our transparent and rules-based process. We’re proud to celebrate the successful completion of this year’s rebalancing with our longstanding friends at Nasdaq, marking another milestone in our shared commitment to market integrity and efficiency.”
FTSE Russell’s Russell Reconstitution concluded at the close of the US equity markets today, June 27th, with the newly rebalanced indexes taking effect when markets open on Monday, June 30th. Although currently rebalanced on an annual basis, beginning in 2026, the reconstitution of the Russell US Indexes will be held semi-annually in June and November. FTSE Russell announced this move to a semi-annual reconstitution frequency earlier this year, with more information available here.
