GigOptix, Inc. (NYSE MKT:GIG), a leading fabless supplier of semiconductor and optical components that enable high speed information streaming, today announced that it will join the Russell Microcap® Index when Russell Investments reconstitutes its family of U.S. indexes on June 25, according to a preliminary list of additions posted June 8 on www.russell.com. Membership in the Russell Microcap Index, which remains in place for one year, means automatic inclusion in the appropriate growth and value style indexes. Russell determines membership for its equity indexes primarily by objective, market-capitalization rankings and style attributes. "Being included in the Russell Index is a validation of the progress we have made over the last five years. As we continue to execute on our growth strategy, we believe our membership will be a valuable tool to help raise our investment profile in the financial community," said Curt Sacks, Chief Financial Officer of GigOptix. Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for both passive and active investment strategies. In the institutional marketplace, an industry-leading $3.9 trillion in assets currently are benchmarked to them. Russell calculates more than 80,000 benchmarks daily covering approximately 98 percent of the investable market globally, 83 countries and more than 10,000 securities. Annual reconstitution of Russell Indexes captures the 4,000 largest U.S. stocks as of the end of May, ranking them by total market capitalization to create the Russell 3000 ® Index and Russell Microcap Index. 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.
