US Market Wrap 9 September: Dow Falls 405 Points as Oil Tops 100 Dollars and Yields Rise

By The Edge Research Team

Wall Street fell across the board on Wednesday as crude oil above 100 dollars a barrel and a higher Treasury curve weighed on equities, with 10 of the 11 S&P 500 sectors lower and only energy rising. The Dow Jones Industrial Average fell 405.41 points, or 0.77 percent, to 52,380.66, the S&P 500 lost 0.48 percent to 7,636.36 and the Nasdaq Composite 0.64 percent to 26,253.34, while the small cap Russell 2000 was the weakest major, down 1.32 percent. The technology heavy Nasdaq 100 held up best, down 0.29 percent, and energy was the only sector to rise, up 1.09 percent, as Brent traded above 101 dollars a barrel after the escalation in the Persian Gulf, per CNBC.

Small caps led a broad decline

The decline was broad. The small cap Russell 2000 dropped 1.32 percent, a full 1.03 percentage points more than the Nasdaq 100’s 0.29 percent slip and more than four times as deep, on our calculation, and among the sectors the steepest falls were in industrials, down 1.51 percent, consumer discretionary, down 1.39 percent, utilities, down 1.17 percent, and real estate, down 1.12 percent. The Dow’s 405.41 point fall follows Tuesday’s 628.18 point drop, leaving the average down 1,033.59 points over the two sessions from its 4 September close, on our calculation. Financials eased 0.43 percent and health care 0.37 percent, while information technology fell only 0.16 percent, the shallowest decline among the fallers and consistent with the Nasdaq 100’s relative resilience.

Only energy rose as oil held above 100 dollars

Energy was the single gainer among the 11 S&P 500 sectors, up 1.09 percent, as crude held above 100 dollars a barrel, while the other 10 fell. The board ran a spread of 2.60 percentage points, from energy’s 1.09 percent gain to industrials’ 1.51 percent decline, on our calculation, and the breadth pointed to a macro driven session rather than an isolated company story, energy alone advancing with crude while higher yields coincided with weakness across the rest of the board. The oil story featured across every session we cover on Wednesday, and the other regional boards are carried below for reference, abridged and verbatim from our own wraps of 9 September.

The curve rose across maturities

The Treasury’s official par curve for 9 September rose along its length. The 2 year yield rose 4 basis points from Tuesday to 4.43 percent, the 3 year 5 basis points to 4.49, the 5 year 4 basis points to 4.61, the 10 year 3 basis points to 4.83 and the 30 year 3 basis points to 5.28, on our comparison of the Treasury’s 9 and 8 September rows. Over the two sessions since the 4 September close the curve has risen 6 basis points at the 2 year, 7 at the 5 year, 5 at the 10 year and 4 at the 30 year, on our calculation, so Wednesday extended a move already under way. The 1 year rose 2 basis points to 4.17 percent and the 7 year 3 basis points to 4.71, while the 1 month Treasury yield was unchanged at 3.81 percent.

Oil, gold, the dollar and volatility

Brent for November traded at 101.67 dollars a barrel at the 20:23 GMT capture and West Texas Intermediate for October at 96.83 dollars, up 3.83 percent and 4.08 percent respectively against Tuesday’s settlement, our post close snapshots sitting just above the official ICE and NYMEX settlements of 101.21 and 96.05 dollars, up 3.4 and 3.3 percent, carried in our commodities wrap of 9 September. Gold for December was little changed at up 0.10 percent to 4,443.60 dollars. The dollar index was flat at up 0.05 percent to 98.835, and bitcoin eased 0.21 percent to 78,235 dollars on the vendor’s daily basis. The Cboe Volatility Index rose 4.71 percent to 16.46, its second consecutive rise, and is up 13.28 percent over the two sessions from the 14.53 close in our published 4 September wrap, on our calculation.

Why it matters: The session was a rates and oil story rather than a stock specific one, on our reading. The decline was broad, led by the small cap Russell 2000 and by the industrial, consumer discretionary, utility and real estate sectors, while energy alone rose with crude above 100 dollars and the technology heavy Nasdaq 100 fell least. The Treasury curve rose across its length for a second session, up as much as 7 basis points at the 5 year over the two sessions, and that combination, higher yields with oil at its highest settlement since 22 May, per CNBC, points to the market weighing the inflation risk ahead rather than any single company’s news.

Outlook: The producer price index for August lands on Thursday 10 September and the consumer price index for August on Friday 11 September, per our published wraps, the final headline inflation readings before the Federal Reserve’s 15 and 16 September meeting. Because both cover August, Wednesday’s oil move does not feed the energy component of either, on our reading; its weight is on September inflation and on longer term expectations. The European Central Bank decides on Thursday. With the curve higher, energy the only sector to rise and small caps leading the fall, investors enter the releases with the yield move already visible across the market, and a firm August reading, or a sustained oil premium into September, would add to the upward pressure on yields that shaped Wednesday’s session.
