What this is
The RareEarth Index tracks the public companies whose primary business activity is rare earth element production. Modified market-capitalization weighting using free-float, with a 10% single-name cap and iterative pro-rata redistribution. Quarterly weight rebalances; semiannual full reconstitution.
Six eligibility screens, applied in order: activity, exclusion, listing, market-cap floor, liquidity floor, English reporting standard. Eligible exchanges are the named global venues only — NYSE, NASDAQ, TSX, TSXV (with liquidity waiver), ASX, LSE Main, LSE AIM, Oslo Børs, Euronext, HKEX, SGX. Companies listed exclusively on Shanghai or Shenzhen are out of scope.
The full rulebook is on the methodology page. The construction record for the inaugural composition is in the inaugural constituent note.
Composition
Fourteen constituents at inception. Five names sit at the 10% single-name cap; nine carry their natural free-float weights. The full table, with sector classification and cap-binding indicators, is on the constituents page.
Companies that were considered and excluded are documented one by one, with reasons, in the audit trail.
Calendar
The next quarterly rebalance is June 30, 2026. The first semiannual reconstitution is December 31, 2026. The full schedule is on the reconstitution page.
The voice
There is no marketing layer over the math. The methodology speaks; the index reflects what it produces.
