Russell Reconstitution 2026

Preliminary List Update (6/5)

Since our last update shared on May 28th, Russell has confirmed three new Russell Global Quantitative and Derivatives

2000 additions (INFQ, WSHP, ZENA). Russell also confirmed 50 share Strategy

adjustments (excluding changes resulting from corporate actions; see table below). Min Moon AC

As of June 8th, the Russell Reconstitution lock down period will begin and we don’t (1-212 ) 272-8456

expect any material changes to the proforma composition. min.k.moon@jpmorgan.com

For the Russell 1000 Growth, Russell 3000 Growth, and Top 200 Growth

indices, the capping reference date is June 17, 2026. As of June 5th, the Russell

1000 Growth and Russell 3000 Growth indices will not be capped as the

components greater than 4.5% do not reach 45%. So the top weight will be

uncapped and will trigger inflows to Nvidia. We are estimating about $6.7 billion

to buy for NVDA if the Russell 1000 Growth does not get capped during the June

Reconstitution.

The total (gross) trade size of this year’s Reconstitution is estimated at $291 billion

per side ($582 billion buy+sell), a 117% increase from $134 billion per side in

2025. We expect roughly 8.2 billion shares to be traded by the Russell indexers, a

significant increase from last year’s 5.68 billion shares.
