Tacoma, Wash.-based Russell Investments realigns the Russell 3000 index once per year, tracking what it maintains is 99 percent of the U.S. equity market. That index is then broken down to 26 smaller indexes, including the widely watched Russell 1000 index of large capitalization stocks.

The makeup of the Russell indexes for the next 12 months was finalized after the closing bell Friday.

(This version corrects the number of stocks being added from this sector to 10, and adds AECOM Technology to the list.)
