LOS ANGELES--(BUSINESS WIRE)--

Puma Biotechnology, Inc. (NASDAQ: PBYI), a biopharmaceutical company, is set to join the broad-market Russell 3000^® Index at the conclusion of Russell Investments’ annual reconstitution of its comprehensive set of U.S. and global equity indexes on June 28 and effective after U.S. markets open on July 1, according to a preliminary list of additions posted on May 24.

“We are very pleased to be included in the widely referenced Russell Indexes,” said Alan H. Auerbach, Chief Executive Officer and President of Puma Biotechnology. “We believe that inclusion in the Russell 3000 will benefit our stockholders by increasing liquidity and providing exposure to a broader base of institutional investors.”

Reconstitution of Russell’s U.S. Indexes captures the 4,000 largest U.S. stocks as of the end of April, ranking them 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. The Russell 3000 also serves as the U.S. component to the Russell Global Index.

Russell determines membership for its equity indexes primarily by objective, market-capitalization rankings and style attributes. Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for both passive and active investment strategies. Over $10 trillion in assets are benchmarked against Russell’s U.S. Indexes. Russell indexes are part of FTSE Russell, a leading global index provider.
