LOS ANGELES, June 17, 2011 (GLOBE NEWSWIRE) -- RadNet, Inc. (Nasdaq:RDNT), a national leader in providing high-quality, cost-effective diagnostic imaging services through a network of 206 owned and operated outpatient imaging centers, announced today it is set to join the U.S. broad-market Russell 3000® Index when Russell Investments reconstitutes its comprehensive set of U.S. and global equity indexes on June 24, according to a preliminary list of additions posted June 10 on .
Annual reconstitution of Russell's U.S. indexes captures and ranks the 4,000 largest U.S. stocks as of the end of May by total market capitalization. Membership in the Russell 3000, which remains in place for one year, means automatic inclusion in the large-cap Russell 1000® Index or small-cap Russell 2000® Index as well as the appropriate growth and value style indexes. Russell determines membership for its equity indexes primarily by objective, market-capitalization rankings and style attributes.
The Russell 3000 also serves as the U.S. component to the Russell Global Index. Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for both passive and active investment strategies. An industry-leading $3.9 trillion in institutional assets currently are benchmarked to them. These investment tools originated from Russell's multi-manager investment business in the early 1980s when the company saw the need for a more objective, market-driven set of benchmarks in order to evaluate outside investment managers.
