Decreasing the Russell Index Turnover Cost

Methodology Enhancements Have Steadily Decreased Price Pressure at Annual Reconstitution

SEATTLE, WA--(Marketwire - May 23, 2012) - Over the past twelve years, Russell Indexes has steadily decreased the turnover percentage, or the number of index additions and deletions, around its annual reconstitution. While the core of its objective and transparent methodology has not changed since the indexes' inception in 1984, a number of new measures have been introduced to alleviate price pressure around the annual rebalancing.

In particular, three adjustments to the Russell Indexes methodology in recent years have helped to significantly decrease turnover at reconstitution, ensuring that each index remains an accurate reflection of an individual market cap tier.

  • Quarterly IPO Additions - IPOs are now added to the Russell Indexes once every quarter rather than just at reconstitution, and a company that is eligible is added after a minimum of one month seasoning.

  • Provisional and Legacy Indexes - Passive fund managers may now make their portfolio transitions on any day over a two month period, one month prior or one month following the annual reconstitution, based on performance figures provided by Russell.

  • Capitalization Banding - Implementation of a +/-2.5% membership band around market capitalization breakpoints now reduces the number of securities moving between small and large-cap segments at reconstitution, without distorting cap tier performance.

The Russell Indexes methodology around reconstitution has helped to spread any potential arbitrage, or opportunistic trading, over a longer period of time than just at reconstitution, making the transparency of index changes through Russell's rules-based mechanism desirable for passive indexers. Academics have actually argued that Russell Index's transparent and predictable approach to annual rebalancing helps to lessen the potential impact of arbitragers and reduce short-term volatility as index changes can be anticipated days or months earlier.1

Russell has seen the turnover rates of the Russell Indexes around reconstitution decrease in recent years2. The indexes remain market efficient, able to be tracked and duplicated readily to act as a performance standard for active managers and a replicable vehicle for passive investing strategies. The Russell Family of Indexes currently captures 68.2% of U.S. institutional market share, more than any other index family.

The annual Russell Indexes reconstitution final list will be posted to the Russell Reconstitution website on June 25, 2012. For a more information on the Russell family of global indexes, go to the Russell Indexes website.
