New York-based staffing firm Corporate Resource Services Inc. (NASD: CRRS) will join the Russell Global Index when Russell Investments reconstitutes its U.S. and global equity indexes June 27, the company announced today.

Russell indexes are used by investment managers and institutional investors for index funds and as benchmarks for active investment strategies. Approximately $5.2 trillion in assets are benchmarked to the Russell Indexes.

Membership in the Russell Global Index remains in place for one year and means automatic inclusion in the appropriate large-cap, small-cap, all-cap indexes as well as the applicable style, sector and country indexes.

Each June, Russell completely realigns its family of global equity indexes to reflect market changes in the past year. This year’s rebalance will impact approximately $5.2 trillion in assets benchmarked to and nearly $800 billion in assets invested in institutional and retail investment products based on the Russell Indexes.

“This year’s Russell rebalance reflects continued lumpiness in the global economy, with notable shifts in market leadership and important differences across regions and countries,” said Stephen Wood, Russell Investments’ chief market strategist. “U.S. growth continues, albeit at a slower pace than 2013, with small cap, growth-oriented stocks ceding the stage to large-cap value in recent months.”
