FTSE Russell’s preliminary lists for the December 2026 Russell reconstitution, published after the close on November 13, add 125 companies to the Russell 2000 and remove 75. About half of the 91 stocks set to leave the wider Russell 3000 joined only in June.
The short answer. Now that the Russell indexes reshuffle twice a year, 47 of the 91 stocks on the December Russell 3000 deletion list are ones added in June. FTSE Russell’s public lists give no reason.
StockTitan price data suggest most of the 47 were below the size line on the October 30 rank day, and the rest under the $1.00 minimum price. That matters beyond holders. FTSE Russell says about $12.5 trillion was benchmarked to its US indexes at the end of 2025, and funds that track them adjust when the changes take effect on December 11.
The December 2026 Russell reconstitution in three numbers
Sec.01Russell reconstitution 2026 preliminary list: who is joining
125 companies are set to join the Russell 2000, the main index of small US companies. Another 21 are set to join the Russell 1000, the large company index, including Shopify, NXP Semiconductors and Teva.
A third group moves down from bigger company indexes. FTSE Russell lists 10 companies dropping from the Russell 1000 to the Russell 2000, including Olin, Euronet Worldwide, Almonty Industries, Fervo Energy and MSG Rangers.
Health care leads the list with 44 of the 125 additions, followed by financials and industrials. The largest addition by market value is BillionToOne, a health care company. FTSE Russell says it now meets the index’s rule that at least 5% of a company’s voting rights sit with public shareholders.
The big names are on the large company side. FTSE Russell says 12 companies join the Russell 1000 as new members of the Russell indexes, among them Shopify, NXP Semiconductors, Teva Pharmaceutical, Waste Connections and Ferrovial. The summary does not say why they are new to the indexes. Shopify goes into the Russell 1000 Growth index, while NXP and Teva go into the Value index.
Sec.02Which stocks are leaving the Russell 2000 and Russell 3000
75 companies are set to leave the Russell 2000. Nine move up to the large company index, and 66 drop to the Microcap index only, which takes them out of the Russell 3000.
The Russell 3000 deletion list counts every stock leaving the 3,000 company index, so it is longer, at 91 names. It includes the 66 that drop to the Microcap index, and FTSE Russell’s summary does not break down the rest.
Among the names are Cable One, loanDepot, Thryv, Rent the Runway, Wheels Up, Playboy, Douglas Elliman and Tucows. Health care is again the largest group, with 39 of the 91.
Sec.03Why stocks added to the Russell 3000 in June are leaving in December
About half the stocks set to leave the Russell 3000 were added in June. With two reshuffles a year, a small stock can now get in and fall out within six months.
All 47 still traded on November 13. Estimated from StockTitan prices, 42 of them were worth less than $144.0 million on October 30, the size of the smallest Russell 2000 member that day. The other five closed below $1.00, the index’s minimum share price, and their recent average closes were below it too.
How the index is built explains how this can happen. FTSE Russell ranks every eligible US stock by total market value on rank day, and its methodology puts no buffer at the bottom of the Russell 2000. A company just above the line in April can slip below it by October. Under the old yearly schedule, that stock would have stayed in until the next June.
The traffic runs both ways. 23 of the 127 December additions were removed in June, among them Alight, Expensify, Fate Therapeutics, Traeger and Forrester Research.
Sec.04How the December Russell reconstitution compares with June
December is the smaller reshuffle. At the same preliminary stage, it adds about half as many companies to the Russell 2000 as June did, and about a third as many to the Russell 1000.
In June, FTSE Russell’s preliminary lists added 237 companies to the Russell 2000, against 125 now. IPOs are the exception, with 18 joining the Russell 2000 now against 17 in June.
FTSE Russell does not say why December adds fewer companies. June’s lists ranked stocks a year after the June 2025 reconstitution, while December’s rank them six months after June.
December also limits some other changes. Share count and float updates apply only above 1% and 3% buffers, FTSE Russell’s summary says. Membership is still ranked on full rank-day values, according to its October 2026 FAQ. Growth and value labels change only for new members and stocks that switch between the Russell 1000 and Russell 2000, as its October 26 preview explains.
The size lines barely moved. The line between the Russell 1000 and Russell 2000 rose 1.7% to about $5.8 billion on October 30, from about $5.7 billion in June, FTSE Russell’s summary says. The smallest Russell 2000 member that day was Magyar Bancorp, worth $144.0 million.
At the top, Krystal Biotech is the largest Russell 2000 member, worth $9.8 billion on October 30, FTSE Russell says. It can sit above the large company line because of banding, a buffer that lets a current member drift past the line before it switches index.
Sec.05Russell reconstitution dates 2026
The new indexes take effect after the market closes on Friday, December 11. From the lockdown on November 30, FTSE Russell treats the changes as final, except in rare cases.
The process started on rank day, October 30, when FTSE Russell took the market values that decide membership. The preliminary lists followed on November 13. Updated lists come out on November 20, November 27 and December 4, according to the FTSE Russell reconstitution page.
Lockdown starts at the open: changes treated as final
Dec 11
New indexes take effect after the close
Dec 14
First trading day with the new members
From November 16 to 27, index users can raise questions about the data in the files, according to FTSE Russell’s October 2026 FAQ. The lockdown begins at the open on Monday, November 30. The new members trade in the indexes from the open on Monday, December 14.
This is the first December reconstitution in more than three decades, FTSE Russell says. The next one is in June 2027, with rank day on the last business day of April.
Sec.06What the Russell reconstitution means for stocks and index funds
Funds that copy these indexes trade to match the new lineup. The changes take effect at the close on December 11.
The money involved is large. FTSE Russell says about $12.5 trillion was benchmarked to its US indexes at the end of 2025. Index funds aim to hold the members, and active funds are judged against them.
FTSE Russell says reconstitution day ranks among the highest-volume trading days of the year. At the June 2026 close, $553.9 billion in US stocks traded, it reports, citing Nasdaq and NYSE data.
For an added stock, that can mean heavy buying from funds on one day. For a removed stock, it can mean heavy selling. How much any one stock is bought or sold depends on its weight in each index, which the public lists do not give.
Whether any name, the 47 June arrivals included, comes off the lists: FTSE Russell’s updated lists on November 20, November 27 and December 4.
Our numbers
These figures are our calculations from the sources linked in this article. The round-trip counts compare a preliminary December list with a final June list, and the December list can still change before the lockdown.
47 of the 91 Russell 3000 deletions were June 2026 additions: each December deletion matched by ticker and company name against FTSE Russell’s final June 2026 Russell 3000 addition list.
About one in five of June’s 224 additions is on the December deletion list: the same 47 matches, against every name on the June list.
23 of the 127 Russell 3000 additions were removed in June 2026: the same match against the final June 2026 deletion list.
42 of the 47 were worth less than $144.0 million on October 30: estimated from October 30 prices and November 13 share counts in StockTitan’s data, counts assumed unchanged.
The other five closed below $1.00 on October 30: StockTitan’s daily prices, with their 30-day average also below $1.00.
About half as many Russell 2000 additions as June: 125 at December’s preliminary stage against 237 at June’s, from FTSE Russell’s two announcements.
Sec.07Frequently asked questions
There are two in 2026. The June reconstitution took effect after the close on June 26. The December reconstitution takes effect after the close on Friday, December 11, 2026, and the new members trade in the indexes from Monday, December 14.
It is when FTSE Russell rebuilds its US indexes, including the Russell 1000, Russell 2000 and Russell 3000. It ranks eligible US stocks by total market value on rank day and resets which company belongs in which index. Since 2026 it happens twice a year, in June and December.
After December 11, 2026, the next one is in June 2027. Under FTSE Russell’s rules, its rank day is the last business day of April and the changes take effect after the close on the fourth Friday of June.
Yes, on the preliminary lists. FTSE Russell names Shopify among 12 companies joining the Russell 1000 as new members of its indexes, along with NXP Semiconductors, Teva Pharmaceutical, Waste Connections and Ferrovial. Shopify goes into the Russell 1000 Growth index.
FTSE Russell posts them on its reconstitution page as four files, the Russell 3000 and Russell Microcap additions and deletions, all linked on this page. On StockTitan, many companies also announce in their own press releases that they are joining the index, and the market cap rankings show where a company stands by size.
