Flex Pharma, Inc. (NASDAQ: FLKS), a biotechnology company that is developing innovative and proprietary treatments for exercise-associated muscle cramps, nocturnal leg cramps, and spasms associated with severe neuromuscular conditions, today announced that it has been added to the Russell 3000, Russell 2000, and Russell Microcap Indices as part of Russell Investments' first quarter 2015 IPO additions.

The Russell 3000 Index measures the performance of the largest 3,000 U.S. companies representing approximately 98% of the investable U.S. equity market. The Russell 3000 Index is constructed to provide a comprehensive, unbiased and stable barometer of the broad market and is completely reconstituted annually to ensure new and growing equities are reflected.



The Russell 2000 Index measures the performance of the small-cap segment of the U.S. equity universe. The Russell 2000 Index is a subset of the Russell 3000 Index representing approximately 10% of the total market capitalization of that index. It includes approximately 2,000 of the smallest securities based on a combination of their market cap and current index membership.

The Russell Microcap Index measures the performance of the microcap segment of the U.S. equity market. Microcap stocks make up less than 3% of the U.S. equity market (by market cap) and consist of the smallest 1,000 securities in the small-cap Russell 2000 Index, plus the next 1,000 smallest eligible securities by market cap.
