Week Ending September 18, 2026

S&P 500: -0.08%
NASDAQ Composite: +0.72%
Dow Jones Industrial Average: -1.69%

Weekly index price changes compare the September 18 close with the September 11 close and exclude dividends.

Market Takeaway

U.S. equity markets finished the week mixed. The NASDAQ Composite gained 0.72%, while the S&P 500 slipped 0.08% and the Dow Jones Industrial Average declined 1.69%. The different results showed that the major benchmarks did not move together.

The Federal Reserve raised its benchmark interest-rate target by a quarter percentage point as inflation remained elevated. Economic reports offered a mixed picture: retail spending increased, unemployment claims declined, and housing data showed uneven activity.

Lennar’s quarterly results added a company-level view of housing affordability pressures. Meanwhile, the VIX finished Friday below its midweek closing level, indicating that options-implied near-term volatility eased late in the week.

Thematic Drivers of the Week

1. The Federal Reserve Raised Interest Rates

What happened: On September 16, the Federal Open Market Committee voted unanimously to raise the federal funds target range by 0.25 percentage point to 3.75%–4.00%. The statement described continued economic expansion and elevated inflation.

Why it mattered: A higher policy rate can affect borrowing costs for households and businesses and influence how investors value future earnings.

Market context: The major stock indexes ended the week with different results. Their weekly changes do not isolate the effect of the Fed’s decision from other developments.

2. Consumer Spending Increased

What happened: August retail and food-services sales increased from July, according to the Census Bureau’s advance report.

Why it mattered: Retail sales provide a view of household spending on goods and food services. Because the figures are not adjusted for inflation, higher dollar sales do not necessarily mean an equivalent increase in purchase volumes.

Market context: The report added evidence of continued spending. It does not, by itself, establish what drove stock prices during the week.

3. Housing Conditions Remained Uneven

What happened: Building permits declined in August. Estimates of total housing starts and single-family starts moved in opposite directions, although those monthly changes were not statistically significant. Lennar reported lower quarterly earnings and fewer orders than a year earlier.

Why it mattered: Housing activity and homebuilder results offer different perspectives on demand, financing costs, and affordability.

Market context: These findings provide economic and business context rather than a direct explanation for the week’s index returns.

Earnings Recap Key Companies in Focus

Lennar Corporation LEN - Reported September 16

Fiscal third quarter ended August 31, 2026. Comparisons below are with the same quarter of fiscal 2025.

Results:

·         Revenue: $8.046 billion, compared with $8.810 billion.

·         GAAP net earnings attributable to Lennar: $283.9 million, compared with $591.0 million.

·         GAAP diluted earnings per share: $1.19, compared with $2.29.

·         Adjusted diluted earnings per share: $1.23. This company-defined non-GAAP measure excludes mark-to-market technology investment losses and one-time financial-services items.

·         New orders: 20,879 homes, down 9% year over year. Deliveries: 20,840 homes, down 3%.

Takeaway: Management cited affordability and mortgage-rate pressures and reduced its full-year delivery target to 80,000–81,000 homes from 82,000–83,000. That target is management guidance, and actual results may differ. One company’s results do not represent the entire housing market.

Major Economic Reports Recap

Retail Sales - Released September 16

August retail and food-services sales totaled an estimated $773.9 billion, up 1.2% from July and 6.0% from August 2025. July’s monthly decline was revised from 0.6% to 0.5%. The figures are seasonally adjusted, are not adjusted for price changes, and remain subject to revision.

Economic Takeaway: Spending increased in dollar terms, but the report does not separate price changes from changes in the volume of purchases.

Import and Export Prices - Released September 16

August import prices rose 0.7% from July and 7.0% from a year earlier. Export prices increased 0.6% for the month and 8.6% year over year. These indexes may be revised.

Economic Takeaway: Internationally traded goods and services continued to show price increases. These measures differ from consumer inflation and should not be treated as substitutes for CPI or PCE inflation.

Housing Starts and Building Permits - Released September 17

August housing starts were estimated at a seasonally adjusted annual rate of 1.275 million, down 2.6% from July. Single-family starts were estimated at 918,000, up 7.6%. Both monthly changes had confidence intervals that included zero, meaning neither change was statistically significant. Building permits declined 2.7% to an annual rate of 1.394 million. The estimates are subject to revision.

Economic Takeaway: The report showed mixed readings. Sampling uncertainty limits the conclusions that can be drawn from one month of housing-start estimates.

Weekly Unemployment Claims - Released September 17

Initial claims were 196,000 for the week ending September 12, down 10,000 from the preceding week. The four-week average declined to 203,250. These are advance estimates and may be revised.

Economic Takeaway: Fewer new claims were filed during the week. Claims provide timely information about layoffs but do not measure every aspect of employment or hiring.

Technical Perspective

The Cboe Volatility Index, or VIX, closed at 14.81 on September 18, according to FRED. That was below its September 16 closing level of 17.71.

Interpretation: The VIX reflects options-implied expectations of near-term S&P 500 volatility. Its decline from midweek indicates that expected volatility eased over those sessions. It does not predict market direction or guarantee that conditions will remain calm.

Key Takeaways for Investors

·         The NASDAQ advanced, while the S&P 500 and Dow declined for the week.

·         The Fed raised its policy-rate target as inflation remained elevated.

·         Retail spending increased in dollar terms, while housing data and Lennar’s results showed uneven conditions.

·         Weekly unemployment claims declined, and the VIX eased from its midweek closing level.

Looking Ahead

The September 21–25 calendar includes reports on economic activity, housing, manufacturing orders, and consumer sentiment, along with selected consumer-facing company earnings. Scheduled dates can change.

Earnings to Watch This Week

·         AutoZone (AZO), September 22: Fiscal Q4 2026 results are scheduled before the market opens. The report may provide context on automotive-parts demand.

·         General Mills (GIS), September 23: Fiscal Q1 2027 results are scheduled for the morning. Sales volumes and pricing may offer context on packaged-food spending.

·         Darden Restaurants (DRI), September 24: Fiscal Q1 2027 results are scheduled before the market opens. Restaurant sales may provide another perspective on discretionary spending.

Economic Data to Watch

·         September 21: Chicago Fed National Activity Index for August, scheduled at 8:30 a.m. ET.

·         September 24: Weekly unemployment claims are expected under the regular Thursday release schedule.

·         September 24: August new home sales, scheduled at 10:00 a.m. ET.

The Q2 GDP third estimate and August Personal Income and Outlays report, which includes PCE inflation, are scheduled for September 30, outside this week.

Fed Events to Watch

Vice Chair Philip Jefferson is scheduled to discuss discount-window modernization and Treasury-market functioning on September 22. Governor Michael Barr is scheduled to speak on housing on September 23. The Fed’s survey of dealer financing terms is scheduled for September 24. No FOMC meeting or minutes release is scheduled for this week. Individual officials’ remarks are not Committee policy decisions.

Closing Thought

Last week’s reports showed how different parts of the economy can move in different directions. Retail spending increased, housing conditions were uneven, and the major stock indexes posted different results. A single headline captures only part of that picture.

Weekly developments provide context for understanding markets. Their significance can vary with a household’s goals, time horizon, and cash-flow needs.
