Dual Commencement: The Russell Index Shift to Semi-Annual Rebalancing

• For the first time in 37 years, the Russell rebalance is moving to a twice-a-year schedule (June and December), ensuring the indexes stay dynamic and reduce “style drift” from fast-growing stocks.

• Moving from the Russell 2000 to the 1000 is a major corporate milestone that triggers massive institutional buying, with hundreds of billions of dollars trading hands during the transition.

• Whether through low-cost core holdings, active value plays, or high-octane trading tools, investors have multiple ways to play this biannual “commencement” event.

The migration from the 2000 to the 1000 is typically a hallmark of corporate success, as well as a significant catalyst for institutional capital flows. The owners of the FTSE Russell indexes, the London Stock Exchange Group (LSEG) noted that $102.5 billion was traded on the Nasdaq and $114.7 billion on the NYSE during the last rebalance (June 2025). Another interesting factoid is that the Russell US Indexes were reconstituted quarterly in 1984, before changing to semi-annual in 1987 and subsequently, annual in 1989. Now, 37 years later, it’s back to semi-annual.

For investors, the migration of names from the 2000 index to the 1000 index signals this “graduation” of sorts. Additionally, it leaves a void in the Russell 2000 that could be filled with a fresh batch of growth names. Moreover, an additional rebalance happening near the end of the year means that companies that saw parabolic growth since June get another reassessment to see if they move to the Russell 1000.

The first rebalance is still scheduled for late June, but a second rebalance is slated for December. This move to two rebalances makes the Russell 2000 and 1000 indexes more dynamic to better reflect market cap changes.

The road to the June 26 finalization (or commencement, to use the graduation theme) is a multi-step process, beginning this week with Rank Day on April 30. Rank Day provides a snapshot of potential graduates (like a credit check with a high school counselor to assess requirements), which ultimately leads to the June rebalancing (or again, commencement).

Below is a summary of important dates to note leading up to the first rebalance of the year:

When a stock migrates from the 2000 to the 1000, it often experiences a shift in investor base. It resembles a move from big fish in a small-cap pond to small fish in the large-cap pond. While this can sometimes lead to short-term selling pressure, as small-cap managers exit their positions, it can open the door for inflows from large-cap institutional funds and ETFs. In turn, here are ETFs that track these Russell indexes, namely the 2000 that investors may want to watch:

1. iShares Russell 2000 ETF (IWM A-)

In terms of assets under management (AUM), IWM is the biggest of the big tracking the Russell 2000. As such, it’s a direct way to play the rebalance happening in both June and now December. The second rebalance helps to prevent the Russell 2000 index from holding on to “graduates” whose market caps are due for a move to to the Russell 1000. This brings us to the next ETF from the iShares brand.

2. iShares Russell 1000 ETF (IWB A)

If the Russell 2000 is high school, then the Russell 1000 would be akin to post-secondary education. With semi-annual updates taking place, this allows IWB to absorb the companies witnessing exponential growth. Thus, this makes IWB a more dynamic play on large-cap companies that can ride the momentum of these “graduates” versus the previous annual rebalancing.

3. Avantis U.S. Small Cap Value ETF (AVUV )

In the current macro environment, higher-for-longer interest rates warrant a quality screener. This is especially the case with small-cap companies operating with heavy leverage. That said, the AVUV is ideal for investors looking for a value-focused tilt in the Russell 2000. With a semi-annual rebalance, AVUV’s active management can allow for a greater opportunity set with companies moving in or out of the index to build higher conviction portfolios that emphasize quality and value. At just 25 basis points, it’s also competitively priced, given its active management.

4. Vanguard Russell 2000 ETF (VTWO A-)

For those focused squarely on limiting costs, Vanguard is the ideal place to look. With an expense ratio of just six basis points, VTWO is a prime alternative for cost-sensitive investors seeking small-cap exposure with greater diversification thanks to its almost 2,000 holdings.

5. Direxion Daily Small Cap Bull 3X Shares (TNA A-)

For event-driven traders, this could be a potential play on the reconstitution. These rebalancing events could result in high volumes, creating the perfect backdrop for traders. TNA, in particular, is ideal for those looking to add three shots of espresso to their bullish position on the Russell 2000. A second rebalance in December now means the door is open for two events to trade the Russell 2000 per year. Conversely, those looking to fade a bullish move could take the other side, with Direxion Daily Small Cap Bear 3X Shares (TZA A-).
