Russell Rebalance: What Happened?

July 01, 2020

Summer has arrived and with it comes the annual “Russell Rebalance,” or as FTSE Russell — the index administrator — officially calls it, the Russell Reconstitution. The last Friday in June brings a unique set of challenges for investors managing to one of Russell’s many indices. More than half of U.S. equity investment managers benchmark to a FTSE Russell Index and the Russell rebalance affects an estimated $9 trillion across these products.¹ The entire family of Russell U.S. indices is recast to reflect changes in the U.S. equity markets over the preceding year. Essentially, the rebalance resets market cap weightings and style designations, which ultimately drive shifts in the underlying sector distributions. This creates one of the highest trade-volume days of the year.

The market’s appreciation over the longest bull market in history pushed the market cap breakpoint between the asset classes to a peak in 2018 of $3.7 billion. As a result, the market cap threshold for constituents to be placed into either the large- and mid-cap focused Russell 1000 Index or the small-cap focused Russell 2000 Index has grown 150% since the Great Financial Crisis.

This past Friday, June 26th, marked the official reconstitution day. Notable movements in this year’s rebalance revolved around a few key sectors: Financials, Health Care, Industrials, and Information Technology. The Russell 1000 saw little movement in sector allocation, while the respective style indices, the Russell 1000 Growth and Value benchmarks, experienced the brunt of change. Technology now comprises a record 43% of the Russell 1000 Growth Index, a 2.3% rise, while the Industrials allocation fell to 4.6%, from 7.3%. The Russell 1000 Value Index was the recipient of those Industrials companies, rising from 9.6% to 12.4%.

From a market cap perspective, many banks within the Russell 1000 Financials sector moved to the small-cap index as investors sold economically sensitive stocks in the first quarter of the year. The Russell 2000 Index saw a 1.6% increase to the sector, bringing the total weight in Financials to 16.2%. As expected, many of these banks qualified for the Russell 2000 Value Index, which now has a nearly 29% weight to the sector. Likely the largest hurdle for active managers navigating the rebalance is the increased allocation to Biotechnology, an industry within the Health Care sector. These securities, many of which do not make money and have no established products, go against the investment philosophies of many fundamentally driven active managers. The Russell 2000 Growth Index now has a more than an 18% allocation to the industry. As managers settle into their new benchmarks, it will be pertinent to discuss these sectoral and capitalization changes in the context of future performance expectations.
