"Russell U.S. Indexes
On the last trading day in May, Russell ranks the 4,000 largest U.S. stocks by market capitalization. After the initial list of 4,000 eligible participants is determined, the shares outstanding for each company are adjusted for corporate cross-ownership and large private holdings. Therefore, the Russell Indexes include only the investable portion of the universe—that segment in which investors can freely transact shares. "
