Small Stocks Are Down 5 Weeks in a Row. Here's What's Going On

The Russell 2000 fell for five straight weeks through Oct. 9, 2026, according to WSJ live market coverage.

The index follows about 2,000 smaller U.S. companies. It shows how smaller stocks are doing, according to FTSE Russell.

Reuters market data for the Russell 2000 Index (.RUT) listed Today's Open at 2,797.69 against a Previous Close of 2,794.13. As of Oct. 9, 2026, that dataset put the 1-month change at -3.90% and the 1-year change at +13.71%.

Borrowing costs were high going into that drop. FRED listed the 10-year Treasury yield at 5.28% on Oct. 7, 2026, not seasonally adjusted. Yield means the yearly interest the government pays to borrow. The 30-year was at 5.67% and the 2-year at 4.77% on the same date. The gap between the 10-year and 3-month borrowing cost was 0.99 on Oct. 8, 2026 versus 1.06 on Oct. 7, 2026. The monthly average for the 10-year was 4.99% for September 2026 and 4.68% for August 2026.

The drop came as longer-term borrowing costs moved up. Reuters reported Wall Street closed lower on Wednesday as long-dated U.S. Treasury yields resumed their climb. As background, WSJ coverage from Sept. 25 reported the 10-year yield hit a high of 5.228% before pulling back that Friday and ended at 5.18%, described at the time as a fresh 19-year closing high.

The next roster update has a set date. The newly reconstituted Russell indexes take effect after the market close on Dec. 11, 2026, according to FTSE Russell. Russell announced the reconstitution of the Russell U.S. Indexes will change from an annual to a semi-annual schedule in 2026.

The broader context here is about a pullback, not a wipeout. A -3.90% drop over one month next to a +13.71% gain over one year means recent momentum stalled. Five weeks can hurt short-term results and force desks to check borrowing and cash cushions. It is too short to reset index weights.

In my view, rates matter more than the five-week headline. A 10-year yield above 5.2% with a gap near 100 basis points is tough for small borrowers. One hundred basis points equals one percentage point. Think of higher yields like heavier gravity for small companies that need loans or must refinance. The step up from August to September shows this was not a one-day jump.

Looking at what this means for implementation, December timing counts. A twice-a-year reset leaves less time to rank stocks and rebalance. Managers running small-cap funds or index-linked products will need to plan for turnover under choppy prices. The five-week slide does not decide who gets in or out, but it affects size cutoffs, adds and deletes, and the cost of catching up after Dec. 11.
