2021 Russell Index Reconstitution Results

Explore Topics and Trends impacting today's markets

In the midst of this year’s Russell Reconstitution, we took a look at the importance of the annual event. And now that results[1] of this year’s recon are in, there are some key statistics worth highlighting.

Highlights of the Russell Recon Results

This year’s reconstitution reveals the U.S. equity market increased in size, with the total market cap of the Russell 3000 Index up 51.9% from $31.4 trillion as of last year’s rebalance, to $47.7 trillion based on this year’s rank day (May 7, 2021).

Overall, this year’s recon is characterized by the outperformance of the small cap Russell 2000 Index, driven by both economic stimulus and recovery in the markets as vaccination rates propel economies to open to pre-pandemic levels. Moving forward, the performance of these cyclical, small cap, growth and value stocks may strengthen as the U.S. economy continues to accelerate upward, ultimately providing more opportunities for market participants to manage their exposure.

Russell 1000 Index:

  • Representing the U.S. large cap market segment, the total market cap of the Russell 1000 Index increased 49.5% to $44.1 trillion, up from $29.5 trillion as of last year’s reconstitution.
  • The largest five companies in the Russell U.S. Indexes have remained unchanged since 2019’s reconstitution, but the order of them has since changed.
  • Four companies surpassed the $1 trillion market capitalization mark, up from three last year, with Alphabet joining Apple, Microsoft and Amazon.com.
  • Tesla and J.P. Morgan Chase entered the top 10 companies by market capitalization, replacing Proctor & Gamble and Walmart. The top 10 companies had a total market capitalization of $10.9 trillion, up 53% vs. 2020, and representing almost one-quarter of the total market capitalization of the Russell 1000 and 22.9% of the Russell 3000.
  • Five IPOs are being added to the Russell 1000 Index at this year’s reconstitution, as 26 other companies are also joining the Russell U.S. Indexes universe.

Russell 2000 Index:

  • Representing the U.S. small cap market segment, the total market capitalization of the Russell 2000 Index increased 84.2% to $3.5 trillion, up from $1.9 trillion as of last year’s reconstitution.
  • 38 IPOs were added to the Russell 2000, 21 of which are classified in the healthcare industry.
  • The largest company in the index (with banding applied) is Performance Food Group, with a total market cap of $7.3 billion, representing a 65.9% increase over last year’s largest company.
  • The smallest company in the Russell 2000 (Velocity Financial) has a total market cap of $257.1 million, an increase of 171.2% from $94.8 million in 2020.


Year-to-year changes in the breakpoint between the Russell 1000 and the Russell 2000 (i.e. the market capitalization that demarcates the boundary between large-cap and small-cap sectors) create a useful gauge of secular growth in market valuations. Reflecting a promising 12 months for U.S. small-cap shares and economic recovery, the latest reconstitution saw the breakpoint between large-cap and small-cap stocks increase 73.3% from $3.0 billion in 2020 to $5.2 billion this year.

Record Number of Banks Removed

The surge in IPO activity in the past 12 months has been remarkable. More than 850 companies have gone public in the U.S., raising a record $173 billion, which is its highest level of activity dating back to February 1997. The market cap threshold for inclusion in the Russell 2000 has risen to $257 million, the highest since 2007.

U.S. banks have lagged the post-pandemic market recovery, and as a result, many were dropped from the Russell 2000 this year. In fact, a record number of financial services companies were deleted from the Russell 2000 Index this year.

Small Cap Russell 2000 Outperforms

Away from the limelight given to FAANG and Nasdaq stocks, small-cap shares saw a tremendous run over the last 12 months. And for those investors looking to invest in small-cap stocks available in the U.S. stock market, the go-to index became the Russell 2000.

Comparing June 25, 2021, to the same day in 2020, the price of the Russell 2000 Index increased by 66%.

Exhibit 3: Russell 2000 Index Historical Price

Like most equity indices, the price of the Russell 2000 initially took a steep dive with the shutdown of the world economy as a result of COVID-19.

Small cap outperformance was a trend that began with a surge in performance in Q4 2020, while closely tracking the vaccine- and stimulus-fueled rise in long-dated U.S. Treasury yields. This macroeconomic backdrop aided the cheaper cyclical stocks that make up a bigger portion of the Russell 2000 small-cap index rather than the pricier tech stocks that dominate the larger Russell 1000 and the Nasdaq.

This rotation into cyclical stocks has slowed since mid-March with the recent stabilization of government bond yields, and release of consensus-beating quarterly earnings favoring a shift back to growth stocks. Nonetheless, the Russell 2000 has surged to a new, higher level in 2021, and when compared to its index counterparts, the performance of the Russell 2000 is unmatched.

Growth to Value Shift

The year 2021 saw a rise in both the Russell 1000 and 2000 Value Indexes, much of that driven by the healthcare industry. Specifically, the Russell 1000 Value Index saw an increase in the healthcare industry, whose weight increased from 11.8% in 2020 to 16.2% of the index in 2021. Similarly, the Russell 2000 Value Index also saw an increase in the weight of healthcare-classified stocks, from 5.6% in 2020 to 10.5% this year.

There are times, especially after major market downturns, that value can be found in both the value and growth indexes. There are distinct differences in the sector weights within the two style indexes; as such, major moves in particular sectors can have an outsized influence on the relevant index performance. This is especially true when we look at these indices throughout the COVID-19 pandemic.

From the start of the pandemic, marked by the market low on March 23, 2020, to the all-time highs of the S&P 500 and Nasdaq on September 2, 2020, the best performing sectors were technology and consumer discretionary. Both  ofthese sectors represent a much larger portion of the Growth Indexes: 60% of the Russell 1000 Growth Index and 35% of the Russell 2000 Growth Index. In contrast, they only account for about 20% of the Value Indexes. During this phase, growth outperformed value.

Also of note is that tech represents a much larger share of the Russell 1000 Growth Indexes than the Russell 2000 Growth Index. That bias also explains why large caps were outperforming in the early part of 2020 and at the start of the pandemic.

Since the all-time highs of September 2, 2020, it’s been an entirely different story. Since then, the best performing sectors have been energy and financials. The combination of those two sectors account for only 2-4% of the two Russell Growth indexes, yet they account for 26% of the large cap Russell 1000 Value Indexes (and an even loftier 32% of the small cap Russell 2000 Value Index). In other words, the narrative over Q4 2020  has been that small cap value has been outperforming.

Driven by numerous fundamental factors, the interplay between growth and value stocks will continue to be a focus for U.S. investors. CME Group’s E-mini Russell Index futures can be used as a risk management tool to hedge the shifts in the Growth and Value Indexes. Russell 1000 Value futures have shown tremendous growth since the 2020 reconstitution, with open interest reaching a record high of 43,302 on June 17, 2021.

Russell 2000 as an Economic Indicator

The performance of the Russell 2000 in 2021 paves the way for its inclusion as one of the major U.S. equity indices, alongside the Nasdaq-100, the S&P 500, and the Dow Jones Industrial Average.

Investors look to equity markets for signs of the health of the U.S. economy. The close correlation of the Russell 2000 to these counterparts, particularly the Nasdaq-100, strengthens its role as an economic indicator.

The annual Russell Reconstitution provides numerous opportunities for market participants to trade and state their opinion about US. .equity markets, and CME Group’s suite of Russell Index futures provides convenient and cost-efficient tools for hedging that exposure.

Amid these historical swings, investors have been utilizing the small cap futures market at record levels, seeking vehicles to enhance portfolio performance and manage market risk. Since the start of the year, we have seen notable increases in volume on Russell 2000 Index-based futures (RTY) as market participants have used our markets to manage small-cap equity market price risk amid significant levels of volatility and continued uncertainty.

Neither futures trading nor swaps trading are suitable for all investors, and each involves the risk of loss. Swaps trading should only be undertaken by investors who are Eligible Contract Participants (ECPs) within the meaning of Section 1a(18) of the Commodity Exchange Act. Futures and swaps each are leveraged investments and, because only a percentage of a contract’s value is required to trade, it is possible to lose more than the amount of money deposited for either a futures or swaps position. Therefore, traders should only use funds that they can afford to lose without affecting their lifestyles and only a portion of those funds should be devoted to any one trade because traders cannot expect to profit on every trade.
