What It Is

RareEarth Index is a rules-driven global benchmark equity index for publicly listed companies in the rare earths industry. Managed by George Clay, it is part of the Clay Indices family. The index tracks companies whose core business is related to the production of rare earth elements, covering mining, processing and separation, magnet and alloy manufacturing, recycling, as well as advanced exploration companies with clearly defined rare earth resources. From a marketing/SEO category perspective, it is not a customer acquisition, keyword, or site optimization tool; it is closer to a vertical financial data and research website that can be used for content research, industry theme reports, and investment benchmark references.

Core Dimensions

The index emphasizes “methodology as the product.” It applies six screening layers: business activities, exclusions, listing venue, market capitalization threshold, liquidity threshold, and English-language reporting standards. Eligible exchanges include NYSE, NASDAQ, TSX, TSXV, ASX, LSE, Oslo Børs, Euronext, HKEX, SGX, and others, while companies listed only in Shanghai or Shenzhen are explicitly excluded. The initial index has 14 constituents, below the target range of 25–35; five constituents reach the 10% single-stock weight cap. Weighting is based on a modified free-float market-cap methodology, with quarterly rebalancing and semiannual reconstitution.

Pricing and Support

The main content does not list subscription pricing, enterprise plans, API pricing, or paid download options. It states that the goal is to provide a transparent, freely available, rules-based global equity benchmark. In terms of support, the site provides methodology documentation, constituent pages, audit records, a reconstitution calendar, and a contact page, allowing users to submit methodology questions, exclusion challenges, and corrections. However, it does not mention live support, SLAs, data APIs, bulk downloads, or third-party terminal integrations.

Pros and Cons

Its strengths are clear rules, a publicly available versioned methodology, and itemized records of excluded companies, making it suitable for research that requires an explainable benchmark. Its pure-play rare earths screening also avoids including diversified companies with only limited rare earth exposure. The drawbacks are that it has only 14 constituents, making the sample narrow and relatively concentrated; excluding companies listed exclusively in Shanghai or Shenzhen affects its ability to fully cover China’s rare earth industry; and there is limited information on historical data, data sources, APIs, and commercial licensing.

Best Fit and Access from China

It is suitable for researchers focused on rare earths, critical minerals, and the upstream side of the energy transition, as well as thematic investment teams and analysts writing industry content. The main content does not specify access conditions from China, nor does it disclose payment methods. If coverage of China’s domestic rare earth industry is needed, it can be supplemented with Wind, Choice, Bloomberg, thematic ETF indices, or a self-built A-share/H-share stock universe.
