In accordance with Russell US ground rules, the reconstitution of the Russell US Indexes will take place after the market close on 25 June 2021. Performed annually, reconstitution ensures that the Russell US indexes continue to accurately reflect the current state of the US equity market and its market segments, including market capitalization (e.g., large and small cap), sector breakdowns, and style structure.
Friday 07 May 2021: Rank day. Russell US Index membership eligibility for the 2021 reconstitution is determined from published information and market capitalizations at market close.
Friday 04 June 2021: Preliminary membership lists are published after market close. This is the catalyst.
Friday 21 May to Friday 11 June 2021: Query period. Users are welcome to query the published data; any corrections will be communicated after market close each day. Merger and spin-off companies will be re-ranked when the transaction is effective between the rank day and the index lock-down. No further re-ranking will occur after.
Friday 11 June 2021. Monday 14 June 2021: Lock-down. No further corrections will be implemented* and the Russell US index reconstitution can be considered final (with any further changes to shares and free float isolated to changes associated with corporate events).
Friday 25 June 2021: The Russell US reconstitution is implemented after market close.
