When Russell Investments reconstitutes its comprehensive set of U.S. and global equity indexes, especially it's broad-market Russell 3000 Index, stocks move. That is certainly the story for biomedical stocks as regular hours trading came to a close on Friday. Today, the annual reconstitution of Russell's U.S. indexes took place and it captured the 4,000 largest U.S. stocks as of the end of May, ranking them by total market capitalization.
Membership in the Russell 3000, which remains in place for one year, also means automatic inclusion in the small-cap Russell 2000 Index as well as the appropriate growth and value style indexes.
