Indexes

One sector did all the work and the index barely registered it. Crude settled about 5% higher after Iran's supreme leader replaced the official who had set out the terms for reopening the Strait of Hormuz with a Revolutionary Guards commander long skeptical of talking to Washington, and the S&P 500 energy group closed up 4.66% — its biggest one-day gain since April 2025. That was worth roughly a fifth of a point to the index, and the rest of the market gave it back: Apple fell 1.62% and Nvidia 2.86%, which between them account for more of the S&P 500 than the entire energy sector does. The S&P 500 traded as high as 7,773.76 in the morning before closing at 7,753.11, leaving it 4.53 points below the record it set on Friday. Breadth told the story the headline hid: the Russell 2000 lost 0.56% and finished at 3,017.40, and nine of the eleven sector funds either closed lower or gained less than 1%.

SPDR S&P 500 ETF (SPY), $773.03 — twenty-three cents from Friday.

Sector Heat Map

The distance between first and second place is the whole picture.

Utilities and real estate at the bottom with long yields higher is the ordinary arrangement, and health care in second place on one company's results is not a rotation so much as an accident of the calendar.

In the News

Rates, FX, Commodities

Long yields rose across the curve, which is the mechanical answer to a 5% move in crude two days before an inflation report. Five-year notes added 4.3 basis points on the session, ten-year notes 5.0, and the thirty-year 3.2 — an even shift rather than a lurch at one tenor.

Crude moved once, in the afternoon, and stayed there. Natural gas rose almost as much in percentage terms with no Iranian input at all; the two markets share a chart page and very little else.

The two crude figures above are exchange settlements, sourced from Reuters; the 16:48 ET screen quote reads twenty cents higher on WTI. Natural gas and gold are likewise quoted after their own settlements. For all the strength, bullion still trades about 21% under its January 28 peak of $5,602.22 — a gap the word "record" keeps getting used to paper over. The dollar index closed at 99.82, the yen weakened to 159.30 per dollar, and the euro eased to $1.1545.

Technicals

The S&P 500 sits 255.08 points above its fifty-day average at 7,498.03 and 215.81 above the twenty-day at 7,537.30. Neither line has been tested since the July low, so the level that matters is the 7,757.64 close from Friday, now the ceiling rather than the floor.

The Nasdaq 100 closed at 29,621.80, holding its fifty-day average of 29,357.26 by 264.54 points. The June 2 peak of 30,660.60 is 3.51% away; the nearest approach this month was 4 August's 927-point gap.

Ten-year notes at 4.699% are within five basis points of where they started August. Two more sessions like this one and the top of the summer range gives way without an inflation report having to do anything.

Coherent lost nearly a seventh of its value without a company announcement of any kind.

Coherent (COHR), hourly. The slide to $325.15 began at the open and never found a bid.

Breakouts & Breakdowns

Breakouts

Vertex Pharmaceuticals (VRTX) — closed at $523.91, up 5.61% on second-quarter results, and finished within $5.68 of its twelve-month closing high of $529.59. The session extended its lead over the twenty-day at $483.02 and the fifty-day at $474.67.

Hewlett Packard Enterprise (HPE) — at $54.68 after a 2.74% gain on a Morgan Stanley upgrade to overweight, sitting $6.08 above its twenty-day average and $1.47 short of the twelve-month closing high at $56.15.

Breakdowns

Coherent (COHR) — fell 14.24% to $325.15, losing the fifty-day at $341.94 by a wide margin. The twenty-day at $295.12 is the next support underneath, and the stock had entered the day up 105% for the year.

First Solar (FSLR) — down 4.29% to $239.33, below the fifty-day at $242.27. The two-hundred-day at $234.49 sits $4.84 lower.

Vertex Pharmaceuticals (VRTX) closed at $523.91, its highest finish since July.

Top Movers

Gainers

Datadog (DDOG), +11.48% to $260.78. Eight brokerages raised price targets into a $280 to $327 band after the software company reported roughly 36% revenue growth and a fifth consecutive quarter of acceleration. Oppenheimer counts more than 750 customers building artificial-intelligence products on the platform, including all ten of the largest such companies, with OpenAI renewing as the largest account on reduced usage. It closed $27.37 under its twelve-month closing high of $288.15.

Akamai Technologies (AKAM), +6.43% to $117.65. UBS raised its price target to $143 from $125 on the security and cloud-delivery business. The gain still leaves the stock under its fifty-day average of $125.35, a more honest description of where it has been.

Salesforce (CRM), +2.47% to $197.51. Its first close above $197 since 2 June, and still $5.86 under a two-hundred-day average it last cleared in January.

Losers

Verisk Analytics (VRSK), -5.55% to $181.18. A Delaware court ordered the data and risk-analytics company to complete its contested $2.35 billion purchase of AccuLynx, a roofing-software business it had been trying to exit. The shares closed beneath their twenty-day, fifty-day and two-hundred-day averages. Deal litigation rarely moves a stock this much; the market is pricing the bill, not the ruling.

Intel (INTC), -4.06% to $97.52. The chipmaker announced a $15 billion common-stock offering, with underwriters holding a thirty-day option on a further $2.25 billion, and said customers were signalling "a strong and sustainable demand environment" for artificial-intelligence computing. Issuing equity into that demand is the part shareholders reacted to. Intel is still up 175% this year and 414% over twelve months, so a 4% day arrives from a considerable height.

Nvidia (NVDA), -2.86% to $217.55. No company news; the stock gave back a fifth of its July advance and took both indices with it, closing well above its fifty-day average at $206.14.

eBay (EBAY), -3.81% to $107.71. Bloomberg reported that GameStop chief executive Ryan Cohen is considering withdrawing the $56 billion offer he made for the marketplace. The shares have round-tripped the entire bid premium and closed under both near averages.

Intel (INTC) closed at $97.52, holding its twenty-day average at $96.68.

Macro Calendar

An empty board. The Conference Board published its Employment Trends Index and the Treasury sold three- and six-month bills, and neither was going to compete with a 5% move in oil.

Notable Earnings This Session

A thin slate on both sides of the bell, with the evening carrying whatever interest there was.

Pre-Open

Seven names crossed the wire before trading began and not one of them registered.

Post-Close

Plug Power reported revenue of $178 million against the $167.74 million analysts carried, with gross margin at roughly breakeven after finishing the first quarter at negative 13%, and guided to 15% to 16% growth. The shares were indicated 5.5% higher before the bell and closed down 3.21%, which is the pre-earnings trade in one line. Archer Aviation also reports this evening, hours after agreeing to buy three Boeing subsidiaries, so the call will be about the acquisition and not the quarter.

Drivers

1. Lumentum reports after Tuesday's close, and the optical-networking group has already voted. Coherent fell 14.24% and Lumentum 7% today with no announcement from either, which is what pre-earnings de-risking looks like when two stocks have run 105% and 142% respectively into a report. Coherent follows on Wednesday evening. A strong Lumentum number would leave today's selling looking like an expensive act of caution.
2. July consumer prices at 8:30 ET Wednesday, with crude having settled at $82.13 in the meantime. The reading covers July, so today's oil move cannot appear in it; what it can do is change how the market reads any energy component that is already there. Futures markets ended last week at 60% odds of a September hold, which leaves a good deal of hike risk still on the board.
3. Super Micro Computer and CoreWeave report Tuesday. Super Micro closed at $31.46, still about forty cents under the $31.86 fifty-day average it spent most of July beneath, and its result is the first real test of whether server demand is running ahead of the components that go into the boxes. Cisco Systems follows on Wednesday, August 12.

Energy Select Sector SPDR (XLE), $60.18. The 4.66% bar on the right is the day.
