Russell Global Indexes
Construction & methodology
The Russell Global Index represents the investable global equity market and its segments comprehensively. It consists of more than 10,000 securities in 47 countries and offers over 300 key subindexes. Consistent with the design of the family of Russell U.S. Equity Indexes, it is constructed using float-adjusted market capitalization weights and represents 98% of the investable global equity market.

Construction of the investable equity universe
- Offers investors a complete global equity market performance benchmark
- Serves as a proxy for asset allocation purposes
- Provides a replicable vehicle for passive investment portfolios with global exposures
Determining index membership
- Screen companies globally by total market capitalization
- Apply minimum size and investability standards, and liquidity screens in order to determine a security's index eligibility
Determining style index membership
- Allocate securities to their home countries (each security is included in one, and only one, country)
- Take the top 98% of companies in the U.S. (Russell 3000® Index) and the top 98% of companies in the rest of the world
- Derive each security's weight in the index using float-adjusted market capitalization
Subdivision of global index
- Rank each stock in the Russell Global Large Cap Index and the Russell Global Small Cap Index by respective variables to determine Valuation (Growth/Value) or Stability (Defensive/Dynamic) styles.
- Valuation style variables: book-to-price ratio to represent value and I/B/E/S forecast medium-term growth and historical sales per share growth to represent growth.
- Stability style variables: EPS variability, ROA, and debt-to-equity to represent quality and total return volatility over two time periods to represent volatility.
- Combine variables to create a composite value score (CVS) for each stock. To ensure that turnover remains low, Valuation style implements a band of +/- .10 at the CVS level to prevent the occurrence of smaller, less meaningful movements
- Rank the stocks by their CVS and apply a non-linear probability algorithm to the distribution to determine style membership weights. Roughly 70% are classified as all value or all growth and 30% are weighted proportionately to both value & growth.
- Modular index construction supports a broad spectrum of sub-indexes based on country, region, sector, size or any other customized needs
- Combine macroeconomic and market criteria to create robust classification methodologies for developed and emerging markets countries
- Global-relative approach to index construction results in a classification system that assigns capitalization tiers (small, mid, large) to all companies regardless of domicile, industry or sector
Special rules in individual countries
- Unavailable shares that are restricted by corporate governance or held by strategic investors
- Securities in countries that do not allow foreign investment
- Fixed income-like securities
- Warrants and rights, trust receipts and royalty trusts, limited liability companies, bulletin board, pink sheet stocks (some global exceptions occur), closed-end investment companies, limited partnerships, exchange traded funds
- Securities with a market capitalization of under $1,000,000 USD
- Securities with an average daily trading volume of less than $150,000 USD
- Qualified Foreign Institutional Investor (QFII) shares in China
- Rules are designed to reflect country specific regulations as well as the characteristics of local capital markets
- China and Hong Kong Special Administrative Region are both recognized as different investment universes
- Russell recognizes shares represented by special depository receipts in countries such as Russia, Israel, the Philippines and others as investable. These underlying shares are added back to free float after the foreign ownership limit adjustment has been applied. Market prices are used to calculate performance
- Daily adjustments for stock splits, dividends and de-listings
- Month-end adjustment of stock buybacks and equity offerings
- Quarterly review of IPO additions
- Annual reconstitution of index
