Russell Reconstitution

A: FTSE Russell believes indexes are designed to represent the entire investable opportunity set. Because markets continually change, there must be a systematic procedure in place to keep the indexes¡¯ representation of the markets or market segments reflective of new market information. Fully reconstituting the indexes annually plus adding eligible IPOs (initial public offerings) quarterly and applying daily adjustments maintains the representative nature of the Russell US indexes while avoiding the unnecessary turnover a more frequent full reconstitution could cause.

A: Maintaining representative indexes must be weighed against the cons associated with making frequent changes to index constituents. In other words, an index must balance the precision of representation with practical and acceptable levels of turnover.

Russell research and Russell client sentiment has supported the annual rebalance schedule, as it strikes a reasonable balance between accurate representation and cost. We originally reconstituted the indices quarterly, then semi-annually. Our extensive research demonstrated that annual reconstitution of the Russell US Indices accurately represents the broad market and the market capitalization segments while minimizing the turnover required to reflect market changes. 

*FTSE client sentiment supports the implementation of semi-annual rebalances for the FTSE Global Equity Index Series (FTSE GEIS). FTSE Russell will continue to engage with clients via consultations to determine if changes to either methodology are necessary. There are no current plans to change the current rebalance process for either series.

A: Beginning on May 24, preliminary lists are communicated to the marketplace and updates are provided on May 31, June 7, June 14, June 21 and June 28.

The newly reconstituted indexes will take effect after the market close on 28 June 2024.

A: On rank day, all eligible US securities are ranked by their total market capitalization. Companies whose stocks are listed on eligible stock exchanges and who pass investability rules are considered for inclusion in the indexes. On announcement date, preliminary additions and deletions are communicated to the marketplace. Following query period and lockdown, changes to the Russell Indexes are implemented after the close of US markets on the fourth Friday in June.

A: At the June 2023 reconstitution, $72.7 billion and $61.7 billion in US stocks traded in the closing moments of Friday trading on the New York Stock Exchange (NYSE) and Nasdaq exchanges, respectively.
