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 at the end of March, June, September, and December.
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 at the end of June and December.
