The Russell 3000 Index, one of the broadest indexes for U.S. stocks, will institute annual changes after the markets close Friday, according to a press release put out by Tacoma-based Russell Investments, which maintains the list. Being added, or deleted, may have an affect on a stock’s price as those who use the list for investment decisions move in or out of shares based on their listing in the index.

The index measures the performance of the largest 3,000 publicly held companies in the U.S.,
which among them “represent about 98 percent of the investable U.S. equity market,” according to the release.

Fourteen Silicon Valley companies will join the index, starting a week from today. The region
will have a net increase of four companies, after accounting for ten local stocks that will be
removed.

Among the companies that will be added are:

Akeena Solar (AKNS)
Applied Signal Technology (APSG)
Callidus Software (CALD)
Calpine (CPN)
