Key Highlights

  • The NFIB small-business optimism index for September is scheduled for 6:00 a.m. ET on October 13, 2026, and consensus is 98.0 to 98.2, compared with 98.7 in the prior reading.
  • Published estimates cluster at 98.0, 98.1 and 98.2, so the forecast implies a slip of roughly half a point to seven tenths of a point, which would be a small step down in sentiment.
  • The Russell 2000 closed at 2,794.48 on October 12, 2026, down 0.45%, and iShares Russell 2000 ETF (NYSEARCA:IWM) tracks that index, though no fund move is cited because published data gave none.
  • Small companies often borrow at floating rates and depend on local demand, so the survey is one of the earliest readings on how higher yields are affecting them.

What the Survey Measures

The National Federation of Independent Business surveys its members each month and compiles an optimism index from questions on hiring plans, capital spending, sales expectations and credit conditions. The September reading is scheduled for 6:00 a.m. ET on October 13, 2026. Consensus is 98.0 to 98.2, depending on the estimate, against a prior reading of 98.7. Own arithmetic, labelled as such: the forecast implies a decline of about 0.5 to 0.7 points. A reading near 98 would be close to the long-run average of the index, which is a stable fact about the survey, so the level is less striking than the direction. Results were not available in the material used for this piece, so the figures are forecasts and not outcomes.

Why IWM Is Sensitive to Small Business Sentiment

iShares Russell 2000 ETF (NYSEARCA:IWM) tracks the Russell 2000, an index of about 2,000 smaller US companies. These firms tend to be more domestically focused than large multinationals, and many rely on bank loans with variable rates. The 10-year Treasury yield read 5.24% on October 12 and about 5.19% on October 13, and higher borrowing costs can squeeze profits for companies with less cash. The NFIB survey covers private owners, not listed firms, so the link is indirect, but the two groups face similar conditions on credit, labor costs and demand. The Russell 2000 closed at 2,794.48 on October 12, 2026, down 0.45%, while the Dow rose 0.38%. That gap shows that the market favored large names that day.

Risks and Cross-Currents

A weaker reading would add to concerns that tight credit is hurting smaller firms, while a stronger one could support the view that demand remains solid. Federal Reserve policy is the main outside factor. Cleveland Fed President Beth Hammack said on October 12 that rates need to go higher, and bets on a December hike remain alive. The September consumer price index on October 14, 2026 could change those expectations. Other tests this week include existing home sales on October 13 and retail sales on October 15. Investors in iShares Russell 2000 ETF (NYSEARCA:IWM) should also remember that small-cap indexes include many companies with little or no profit, which makes them more sensitive to financing conditions than large-cap benchmarks.

Where Things Stand

The NFIB survey is a test for iShares Russell 2000 ETF (NYSEARCA:IWM) because small companies are sensitive to borrowing costs and local demand. The consensus of 98.0 to 98.2, against 98.7 before, points to a small step down, and the release is scheduled for 6:00 a.m. ET on October 13, 2026. The result was not available at this writing, so the numbers are forecasts. The Russell 2000 fell 0.45% to 2,794.48 on October 12, and iShares Russell 2000 ETF (NYSEARCA:IWM) will react to rates and data.
