SEATTLE, Sept. 30, 2011 (GLOBE NEWSWIRE) -- Zillow, Inc. (Nasdaq:Z), the leading real estate information marketplace, today announced its stock was added to the Russell 2000® and Russell 3000® Indexes, effective after the market close on Friday, Sept. 30, 2011. Initial public offerings (IPOs) are added to the Russell Indexes on a quarterly basis in addition to the annual Russell Reconstitution in June.

"We're proud to be included in the Russell Indexes as it's another important milestone for Zillow," said Spencer Rascoff, Zillow CEO.

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.
