What is what
A rebalance resets constituent weights to current free-float market capitalizations, subject to the 10% single-name cap. Rebalances do not add or remove constituents (except where required by a corporate action). The RareEarth Index rebalances quarterly on the third Friday of March, June, September, and December, or the prior US trading day if that Friday is a US market holiday.
A reconstitution applies the full eligibility framework to the entire candidate universe. Companies that no longer meet the screens are removed; newly qualifying companies are added. The RareEarth Index reconstitutes semiannually in June and December, on the same calendar slot as the quarterly rebalance.

Q2 2026 Quarterly Rebalance
First scheduled rebalance. Weights reset to free-float market capitalizations as of the June 18, 2026 close, subject to the 10% single-name cap (methodology §5.2). Free-float share counts and free-float percentages held constant from the inaugural workbook per the standard rebalance-vs-reconstitution distinction; only price and FX inputs refreshed.
No constituent additions or deletions. The cap-bound set is unchanged: Lynas, MP Materials, JL Mag, USA Rare Earth, and Neo Performance Materials remain at the 10% cap. Largest weight shifts in the uncapped tail: Arafura −154 bp (9.10% → 7.56%), Lindian +95 bp (5.53% → 6.48%), Ucore +88 bp (8.02% → 8.90%), Aclara +63 bp, Pensana −60 bp. All other shifts < 30 bp. Neo Performance Materials returned +30.9% in USD terms but the move was fully absorbed by the cap.
Date: third-Friday convention introduced this quarter (replaces the prior end-of-month placeholder). Executed on Thursday June 18 because Friday June 19 was Juneteenth, a US market holiday; the prior-trading-day substitution clause in §8.1 applied. Index level on the rebalance close: 92.35 (−7.65% since inception).
Inception
Index launched with 14 inaugural constituents. Calculation date April 30, 2026. Methodology v2.0. See the Inaugural Constituent Note for the full construction record.
