US Market Wrap 8 September: The Dow Drops 628 Points as Health Care Sinks and Oil Nears 100
Wall Street came back from Labor Day to an oil price near 100 dollars and sold the Dow. The Dow Jones Industrial Average fell 628.18 points, or 1.18 percent, to 52,786.07, its lowest close since 1 September against our published closes, and the S&P 500 lost 0.58 percent to 7,673.52, the 10th consecutive year in which the index has fallen in the session after Labor Day, per Bespoke as carried by CNBC. The Nasdaq Composite fell 0.32 percent to 26,421.41 and the Nasdaq 100 only 0.12 percent, so the technology end of the tape fell least, while the Russell 2000 closed 0.52 percent lower at 2,960.20. Health care was the day’s story: the sector fell 2.55 percent, the largest sector move in either direction in our published sector tables, which begin on 2 September, after Amgen fell more than 10 percent and Stryker more than 7 percent, per the same reporting, and energy rose 1.01 percent with Brent at 98.93 dollars a barrel at our 20:14 GMT read, 1.66 percent above Monday’s settlement on our calculation.
The Dow gives back Thursday’s rally and more
The Dow’s 628 point fall is larger than the 624.16 points it gained on 3 September, on our calculation against our published closes, and it leaves the average 275.88 points below its 2 September close after 2 consecutive declines totalling 900.04 points. Amgen, a Dow component, closed 10.08 percent lower at 393.17 dollars on the vendor’s Dow 30 table after a rival’s cholesterol drug fell short in a study, which lowered expectations for Amgen’s own candidate ahead of late stage data due in 2027 or early 2028, per CNBC, which also reported a rating cut by one broker; Stryker dropped more than 7 percent after management said its peripheral vascular business faces supply constraints through the third and fourth quarters, per the same reporting. The S&P 500’s 0.58 percent decline was about half the Dow’s, and the Nasdaq 100’s 0.12 percent slip came with chip stocks higher: Qualcomm was up 4 percent at midday on a data centre partnership with Amazon Web Services that included warrants for Amazon to buy 25 million shares for 4 billion dollars, and Intel was up more than 7 percent after a broker upgrade, per the same reporting.
3 of 11 sectors rose, and energy led on oil near 100 dollars
Energy led at plus 1.01 percent and utilities followed at plus 0.85 percent, with real estate flat at plus 0.02 percent; the other 8 sectors fell. Health care’s 2.55 percent decline was more than a percentage point deeper than the next weakest, financials at minus 1.43 percent, and materials lost 0.91 percent. Information technology fell only 0.19 percent, consistent with the Nasdaq 100’s relative resilience, on our reading. A global energy exchange traded fund reached its highest level since its 2001 inception on Tuesday morning, per the same reporting, on a day an official source at the Saudi Ministry of Energy said several energy sector facilities in the kingdom’s southern region had been targeted, causing fires and a temporary halt to some operations, per our Middle East wrap of 8 September.
The curve rose across the coupons, with one exception
The Treasury’s official par curve for 8 September put the 2 year at 4.39 percent, up 2 basis points from Friday, the 5 year at 4.57, up 3, the 10 year at 4.80, up 2, and the 30 year at 5.25, up 1; the 3 year was the exception, down 1 basis point to 4.44, on our comparison of the Treasury’s 8 and 4 September rows. The 1 month bill rose 2 basis points to 3.81 percent. The rise came with the New York Fed’s August Survey of Consumer Expectations, published on Tuesday, which put median 1 year inflation expectations unchanged at 3.6 percent and 5 year expectations unchanged at 3.0 percent, with the 3 year reading down 0.1 percentage point to 3.2 percent, while the mean probability that unemployment will be higher in a year rose 1.6 points to 44.4 percent, the highest since April 2020, per the survey. Gas price growth expectations rose 1.7 points to 4.6 percent, per the same release.

Brent for November traded at 98.93 dollars at 20:14 GMT and WTI for October at 94.01, 2.77 percent above Friday’s settlement, the last struck before the holiday, while gold for December fell 1.62 percent against Friday’s settlement to 4,404.00 dollars. The dollar index eased 0.32 percent to 98.854 against Friday’s close, and bitcoin fell 1.00 percent to 78,511 dollars on the vendor’s daily basis. The Cboe Volatility Index read 15.72 at 20:20 GMT, up 8.19 percent from the 14.53 settling read in our published 4 September wrap, on our calculation; the vendor’s prior close field showed 15.30, a Monday reading from the extended session when the regular market was shut, which we do not use as a base.

The US Department of the Treasury’s official daily par yield curve for 8 and 4 September 2026, key maturities, from indicative bid side quotations at or near 19:30 GMT in US summer time; the changes are our calculation; the 1 year rose 2 basis points to 4.15 percent, the 7 year 3 basis points to 4.68 percent and the 20 year 1 basis point to 5.26 percent, and the 1 month bill rose 2 basis points to 3.81 percent.

| Instrument | Level | Change |
|---|---|---|
| CBOE Volatility Index | 15.72 | +8.19% |
| US Dollar Index (DXY) | 98.854 | -0.32% |
| Bitcoin, dollars | 78,511 | -1.00% |
Intraday quotes at the 20:20 to 20:22 GMT settling reads; these are snapshot levels of continuously computed instruments, not equity closes. The VIX change is against the 14.53 settling read in our published 4 September wrap, on our calculation, because the vendor’s prior close field carried a Monday extended session reading; the dollar index is against Friday’s close and bitcoin against the vendor’s daily prior close.
Why it matters: The Dow’s underperformance was heavily single name driven, while the broader decline coincided with higher oil prices and yields, on our reading. The Dow’s 1.18 percent fall carried one Dow name’s 10.08 percent drop, and the sector board’s worst move sat in health care, where the catalyst was company specific rather than oil, while energy was the only sector to rise by as much as 1 percent and information technology barely moved. The macro inputs still leaned the same way as Friday: the coupon curve rose again, the 2 year at 4.39 percent and the 10 year at 4.80, and consumers told the New York Fed that they expect faster gasoline price growth and higher unemployment a year out, without raising their inflation expectations. That combination, higher yields and a Dow led decline with technology steady, is a market positioning for this week’s inflation prints rather than reacting to them, on our reading.
Outlook: The producer price index lands on Thursday 10 September and the consumer price index on Friday 11 September, per our published wraps, the next major inflation releases before the Federal Reserve’s 15 and 16 September meeting, and Tuesday’s oil price puts the energy component of both in focus. The European Central Bank decides on Thursday. Apple’s product event on Wednesday, the first major event under new chief executive John Ternus, per our article of 7 September, is the week’s largest single stock event. The Dow closes below its 2 September level with 2 inflation prints and a Fed meeting ahead, and the sector board says the market has so far kept the oil shock inside energy, on our reading.
