The Open

Today in one paragraph

Wall Street spent Tuesday trading a peace deal that doesn't exist yet. Iran's supreme leader said his country's state of "neither war nor peace" has to end, and U.S. crude settled 1.8% lower at $99.90. The refiners, which have more than doubled in a year, fell 7% to 9%; Valero had its worst day since April 2025. Boeing lost 10.7%, its worst day since 2020, after pushing a faster 737 Max assembly line out to the second half of 2027. UniFirst fell 10.5% on a report that the FTC will try to block Cintas's takeover. Tech did the lifting: chip stocks rose 3% and the Nasdaq 1.2%, as AI-infrastructure names rallied for a second day on Anthropic's IPO filing and a lender group's deal to finance its $63 billion purchase of Broadcom technology. The S&P 500 rose 0.6%, yet fewer than half its stocks went up. The Fed announces its rate decision tomorrow at 2 p.m. Eastern. Our read: stocks are pricing peace in oil and a comeback in AI at the same time. The bond market isn't buying either one yet: the 10-year yield barely moved.

What Happened Today?

The most important stories, through our eyes

Boeing, maker of the 737, says its best-seller won't speed up until late 2027

Boeing BA $168.18 −10.7%GE Aerospace GE $297.66 +3.2%Howmet Aerospace HWM $191.99 −1.2%

What the market heard: If you've flown on a single-aisle jet in America, odds are decent it was a Boeing 737. The latest version, the 737 Max, first flew in 2016, and as of September Boeing had delivered 2,483 of them and still held orders for 4,867 more. Airlines pay most of a plane's price when it's delivered, so the speed of the assembly line is the speed of Boeing's cash. On Tuesday, chief executive Kelly Ortberg told analysts that Boeing is now aiming for 52 Maxes a month in the second half of 2027. It has been building about 47. The holdup is wings, which are coming off the line slower than planned. "I know everybody wants us to go faster but we're going to do it right," he told CNBC.

The quarter had good news in it. Revenue rose 4% to $24.2 billion, free cash flow was $464 million, and the core loss of 34 cents a share was wider than the 21 cents analysts expected. The backlog hit a record $745.4 billion, including more than 6,300 commercial jets. Defense revenue jumped 15% to $7.9 billion. The airliner business lost money, though, with an operating margin of −6.5%, which Boeing blamed partly on the costs of future production changes and on its suppliers. Recent wins didn't help: the Navy picked Boeing to develop its next-generation fighter, and the FAA certified the 737 Max 10, the largest Max, last week. The stock fell 10.7%, its worst day since June 2020, and is now 33% below its January high. GE Aerospace, whose CFM joint venture with France's Safran builds the LEAP engines on every Max, rose 3.2%.
What it might mean: The market didn't sell the quarter. It sold the calendar. At 47 a month, the 4,867 Maxes on order are more than eight years of work, and every month the ramp slips is cash that arrives later. A loss narrower than a year ago and a record backlog can't fix that, which is why they got the worst day in six years. The engine maker rising on the same day makes the point: GE gets paid for engines and for servicing the fleet that's already flying, and fewer new jets keeps old ones in the air longer. Our guess is Boeing stays in the penalty box until the wings show up on time. Monthly 737 deliveries are the number to watch, not the quarterly loss.
What would kill it: Monthly 737 deliveries running clearly above the current pace well before mid-2027, which would mean the wing problem got fixed early.

The 737 Max math
Built per month now (about)	47
Target, second half of 2027	52
Maxes on order (September)	4,867

Years of work at 52 a month	7.8

Third-quarter operating margin, by business

A whiff of peace, and the refiners that doubled in a year have their worst day since April 2025

Valero VLO $387.34 −9.2%Marathon Petroleum MPC $435.98 −7.4%Phillips 66 PSX $268.53 −7.0%HF Sinclair DINO $114.21 −8.8%PBF Energy PBF $73.63 −8.6%Exxon Mobil XOM $179.91 −2.5%

What the market heard: Refiners buy crude oil and sell what they make from it: gasoline, diesel, jet fuel. Their profit is the gap between the two, called the crack spread because a refinery "cracks" heavy oil molecules into lighter fuels. The war with Iran has blown that gap wide open. Valero, the San Antonio refiner whose name comes from Mission San Antonio de Valero, the original name of the Alamo, earned $23.89 a share in the third quarter, against $3.53 a year earlier, and its refining margin was $39.24 a barrel, up from $13.14. Over the past twelve months Valero's stock rose 131%, Marathon Petroleum's 126% and Phillips 66's 105%. (Part of the story behind that "66": the car testing Phillips gasoline did 66 miles per hour on U.S. Route 66.)

On Tuesday Iran's supreme leader, Mojtaba Khamenei, met his top national security official to discuss Iran's conditions for ending the war, and said the current state of "neither war nor peace" needs to end, according to a post on his social media account reported by CNBC. A day earlier Saudi Arabia's defense minister held direct talks with Iran's president in Tehran. Crude slipped, but the fuels fell harder: diesel futures settled 2.8% lower and gasoline futures 2.5%, against 1.8% for U.S. crude, so the refiners' margin shrank. Valero fell 9.2%, its worst day since April 2025, and the rest of the group fell 7% to 9%. Oil producers barely flinched: Exxon lost 2.5% and Chevron 1.6%.
What it might mean: Refiners are the purest stock-market bet on this war, because the war squeezes fuel more than crude. Tankers have to dodge attacks, and as a UBS analyst put it this week, "insurance and freight costs have risen sharply." A 9% drop on one sentence from Tehran tells you how much of these prices is war premium rather than earnings power. The producers held up for a reason: UBS also says global inventories are down about 500 million barrels since February and sees Brent near $110 through year-end, so even peace leaves oil expensive while the world restocks. A refiner's extra margin goes away as soon as the ships move freely. Our call: if the talks go anywhere, the refiners fall first and hardest, well before Exxon notices.
What would kill it: The talks collapsing or a new attack on Gulf energy sites. Diesel futures jumping back above Monday's level would be the first sign.

The FTC may block the uniform deal, and UniFirst sinks below where it started

UniFirst UNF $250.40 −10.5%Cintas CTAS $214.80 −4.9%

What the market heard: You've seen their work even if you don't know their names: the work shirts with a name patch, the floor mats at the entrance, the first-aid cabinet in the break room. Cintas, based outside Cincinnati, is the giant of that business. It began in 1929 when Richard "Doc" Farmer and Amelia Farmer collected used rags from factories, washed them and sold them back. UniFirst, of Wilmington, Massachusetts, is a smaller rival that rents uniforms and also runs nuclear decontamination and cleanroom facilities. In March Cintas agreed to buy UniFirst for $155 in cash plus 0.772 Cintas shares for each UniFirst share, $310 at the time, or about $5.5 billion including debt, promising about $375 million in cost savings within four years. The Croatti family, which controls about two-thirds of UniFirst's votes, signed on, and shareholders approved it in June. The same month the FTC asked both companies for more information, the step that usually means a long look.

On Tuesday Semafor reported that the FTC has told Cintas it will sue to block the deal, citing people familiar with the matter. The commission hasn't voted, and its spokesperson said: "Any decision will not be communicated through the press." UniFirst fell 10.5% to $250.40, below where it closed the day before the deal was announced. Cintas fell 4.9%.
What it might mean: The gap in the table is the market's betting slip. At Cintas's closing price the offer is worth $320.83 a share, and UniFirst trades 22% below that, up from 15% on Monday. The more telling move is Cintas's. Buyers usually rise when an expensive deal looks likely to die. Cintas fell, because its shareholders were counting on those $375 million of savings. Both sides want this, and that matters: a deal this size, with savings this big, usually ends in haggling over which plants and routes to sell, not in a walkout. Our guess is a fight or a fix, not a funeral. At 22% below the offer, UniFirst is priced closer to the funeral.
What would kill it: The FTC voting to sue and Cintas declining to fight in court. Either would push UniFirst toward its stand-alone value and close the question.

The deal math, per UniFirst share ($155 cash + 0.772 Cintas shares)
Value when announced (Cintas at $200.77, March 9)	$310.00
Value at Monday's close (Cintas at $225.93)	$329.42
UniFirst at Monday's close	$279.64 (15.1% below)
Value at Tuesday's close (Cintas at $214.80)	$320.83
UniFirst at Tuesday's close	$250.40 (22.0% below)

Two water companies, one day: Xylem's worst in at least ten years, Pentair's best since 2020

Xylem XYL $92.86 −14.2%Pentair PNR $62.29 +12.8%

What the market heard: Xylem takes its name from the tissue that carries water through plants. It was spun off from the conglomerate ITT in 2011 and bought Evoqua for $7.5 billion in 2023. Its pumps, meters and treatment gear move and clean water for cities and factories in more than 150 countries. On Tuesday it cut its full-year outlook: adjusted earnings of $5.40 to $5.45 a share, down from $5.55 to $5.70, and flat organic sales instead of 2% to 3% growth, blaming "project timing and more cautious spending decisions." Third-quarter revenue fell 3% to $2.2 billion, even as orders rose 10% organically. It also said it will reorganize into three segments, and that the head of its water-infrastructure unit will step down and lead the planned sale of two businesses. Xylem fell 14.2%, its worst day in at least ten years, leaving it 38% below its high of a year ago.

Pentair was founded in 1966 by five former Litton Industries employees to make high-altitude research balloons; the name is "penta," for the five, plus "air," for the balloons. The balloons didn't sell, and neither did the canoes that came next. Today it makes pool pumps and filters, water softeners and filtration. Its third quarter wasn't pretty on the surface: sales fell 4% to $976 million and the pool business shrank 18%. But adjusted earnings came in at $1.18 a share, profit rose in its other two segments, and it kept its full-year adjusted earnings target at about $4.70 while now expecting sales to fall about 3%, better than the 4% to 7% drop it had forecast. Pentair rose 12.8%, its best day since March 2020. It is still 42% below where it stood a year ago.
What it might mean: Both stocks came into the day well below their highs, so the market graded direction, not level. Pentair's sales shrank and it soared, because the year got less bad. Xylem's orders grew and it sank, because the year got worse and the company announced a shake-up with asset sales. The customers explain the split. Xylem sells to utilities and industrial projects, which spend more carefully when money costs 5%. Pentair sells to pool owners, who already took their hit. Xylem's 10% order growth says demand isn't broken; it's slow to turn into revenue. Our guess: Xylem's fix takes several quarters, and patient money gets paid for waiting.
What would kill it: Xylem's revenue failing to grow next quarter despite those orders. That would mean the problem is demand, not timing.

Tuesday across water stocks

Johnson Controls JCI +5.7%. The company traces back to Warren Johnson, who patented the first electric room thermostat in 1883, and today it sells heating, cooling and building controls. Orders rose 44% organically in its fiscal fourth quarter, and its backlog grew 43% organically to $23.0 billion; in the Americas it credited "sustained demand for data centers." It expects adjusted earnings of $6.15 to $6.30 a share in fiscal 2027.
Nucor NUE +5.2%. America's largest steelmaker and North America's largest scrap recycler descends from the REO Motor Car Company of Ransom E. Olds, the Oldsmobile founder. It earned $5.80 a share as its average steel price rose 19% from a year ago to $1,233 a ton, and said fourth-quarter profit should be in line with or modestly higher than the third's.
Cadence Design Systems CDNS +6.5%. Engineers use its software to design chips before anyone builds them. It reported $1.63 billion of revenue and $2.11 a share in adjusted earnings, ended with an $8.2 billion backlog, and now sees about 21% revenue growth this year.
Welltower WELL −5.8%. The health-care landlord, a big owner of senior-living communities, raised its full-year outlook for normalized funds from operations to $6.47 to $6.53 a share. Same-store income from its senior-housing operations rose 21%, and it has closed or agreed to $21 billion of investments this year. Net income was 54 cents a share. The stock fell anyway, and fellow senior-housing landlord Ventas fell 4.7%.
SoFi SOFI +13.4%. Short for "Social Finance," it was started in 2011 by Stanford graduates to refinance student loans and now puts its name on the Rams' and Chargers' stadium. It added a record 1.2 million members, reaching 17.1 million, and raised its full-year adjusted revenue outlook to about $5.04 billion.
JetBlue Airways JBLU +19.0%. The New York low-fare airline jumped the day after its third-quarter report, in which it forecast wider fourth-quarter margins even with fuel expected to cost about 85% more than a year earlier. At $2.82 it is still 56% below its February high.

Big Moves, but No Explanation

Money moves in mysterious ways.

CME Group CME −4.7%

What it is. The owner of the Chicago Mercantile Exchange, the Chicago Board of Trade and the New York Mercantile Exchange, where the world trades futures on interest rates, stock indexes, oil and gold. It also owns 27% of S&P Dow Jones Indices.

What we know. No company news on Tuesday. The other exchange owners fell too: Cboe 3.2% and Intercontinental Exchange 2.9%, while Nasdaq slipped 0.3%. Even after the drop, CME is up 11% over the past month. The VIX, Wall Street's fear gauge, fell 4.7%.

Today vs. other exchange owners

Our guess: exchanges earn more when the world is scared and hedging. A day of peace talk and a falling VIX is a bad day for that business, and after a strong month for the exchanges there was profit to take.

Paychex PAYX −5.6%

What it is. Payroll, HR and benefits for small and midsize businesses: about 800,000 payroll clients. It was founded in 1971 in Rochester, New York.

What we know. No company news on Tuesday. The other payroll companies fell less: ADP 2.7% and Paycom 2.4%. Even after the drop, Paychex is up 11% over the past month; it is 13% below its August high.

Today vs. other payroll companies

Our guess: on a day money ran to tech, the steady payroll names paid for it, and Paychex paid the most.

Ferrovial FER +7.3%

What it is. A Spanish builder and toll-road operator behind Toronto's 407 ETR and express lanes in Texas, North Carolina and Virginia. It trades on Nasdaq.

What we know. It filed an investor presentation on its Tennessee I-24 Express Lanes concession, with a call set for Wednesday. It puts the present value of its payments to Tennessee at $21 billion, against the $24.8 billion published at award, which it says mixed present-value and nominal amounts as the bid rules required. Payments during construction come to $7.7 billion from 2027 to 2033. Even after Tuesday's jump, the stock is 27% below its February high.

Today vs. U.S. infrastructure builders

Our guess: investors had been pricing the $24.8 billion headline as an overpayment, and the deck says the real bill is smaller and spread over decades.

The Earnings Desk

Results, briefly

UPS, which started in 1907 in Seattle as the American Messenger Company with $100 of borrowed money, rose 5.8% to $106.09, its best day in a year. Third-quarter revenue rose 6.7% to $22.9 billion, adjusted earnings were $1.69 a share, and it raised its full-year revenue outlook to about $92.6 billion, from $91.2 billion. The planned cuts in deliveries for its largest customer, Amazon, finished in the second quarter, and it expects nearly $3 billion of savings this year from closing buildings and trimming its workforce. UPS is getting paid for getting smaller. Dropping low-margin Amazon parcels and closing buildings looked like retreat a year ago; now it looks like the plan. The test is whether revenue keeps growing once the cost cuts run out in 2027.

Reported Tuesday after the close
Stock	After hours	The read
Visa V The biggest card network	about −2%	Revenue rose 13% to $12.1 billion and adjusted earnings 17% to $3.48 a share. Payments volume grew 9% and cross-border volume 14%. It raised the dividend 16% to 78 cents.
Seagate STX Hard drives that store the cloud's data	about −7% +3.7% day	Revenue jumped 61% to $4.2 billion, adjusted earnings were $7.68 a share against $2.61 a year earlier, and it guided to $4.8 billion of revenue next quarter. Western Digital slipped about 2% after hours. When a 61% growth rate and a record quarter get sold, the problem is what investors had already assumed, not the numbers.
Enphase Energy ENPH Microinverters for rooftop solar	about −11%	Revenue was $293.3 million, and it guided to $225 million to $255 million for the fourth quarter, after a quarter it said was hurt by "soft residential solar demand," with the expiration of the Section 25D federal tax credit for home solar weighing on the market.

Connecting the Dots

Where we are, and where the puck goes next

Stocks are trading a peace deal. The bond market hasn't signed it.

For most of this year, the war with Iran has been the market's other megatrend. Energy stocks are up 59% in twelve months, refiners have more than doubled, and inflation at 3.7% has the Fed raising rates. Tuesday gave us a preview of what peace would do to all that, and the preview was lopsided.

One sentence from Tehran took 7% to 9% off the refiners. The oil producers barely moved, which tells you the market thinks crude stays expensive even if the shooting stops. The money went to the other end of the market: chip stocks rose 3%, the Nasdaq 1.2%, and the AI-infrastructure names that had been beaten up all month bounced hard, with Nebius up 11% and Western Digital up 7% after Anthropic's IPO filing. It was not a broad rally. Fewer than half of S&P 500 stocks rose, and the equal-weighted S&P 500 gained just 0.1%. The market didn't buy stocks. It sold the war and bought AI.

Now look at the bonds. If peace were coming, oil would fall, inflation would cool, and the Fed could stop raising rates. That's the story the AI rally needs, because companies borrowing hundreds of billions for data centers live and die by the 10-year yield. The 10-year ended Tuesday at 5.00%, barely changed. Futures still price about a 90% chance of a rate hike in December, according to CME FedWatch, and in CNBC's Fed survey, 93% of respondents expect the Fed to hold on Wednesday, 76% expect a December hike, and on average they see the 10-year above 5% for the rest of the year. The stock market is trading a cease-fire. The bond market is trading the Fed. By December only one of them can be right.

Remember too where this starts. On the averages, the market looks healthy: about 62% of S&P 500 stocks sit above their 50-day average, up from about a quarter a month ago. But the S&P 500 is still below its October 6 high, small caps are about 8% below theirs, and the midterms are a week away. Our read: the peace trade is real but early, and the place to see it isn't AI. It's what the refiners just did. Assets that are pure war premium fall first. The AI comeback needs lower yields, and lower yields need the Fed, not Wall Street, to believe the war is ending. Tomorrow at 2 p.m. we hear which way the Fed leans.

Where the puck goes next: our odds through December

Neither war nor peace45%

Talks drag past the midterms, crude stays between $95 and $110, the Fed holds tomorrow and hikes in December, and the 10-year hangs around 5%. Refiners win back some of Tuesday's loss; AI chops sideways. Winners: oil producers, short-term Treasuries, banks. Losers: long bonds, homebuilders, cash-hungry AI infrastructure.

You'll know it's this one if WTI holds above $95 and futures keep the odds of a December hike above 75%.

A real deal30%

A framework agreement by mid-December. Ships move through Hormuz, WTI drops below $85, the December hike gets priced out, and the 10-year slides toward 4.6%. Winners: chips, airlines, homebuilders, small caps. Losers: refiners first, oil producers later.

The tell: WTI settling below $90 while the 10-year closes below 4.8%.

The talks fail25%

Escalation in the Gulf. Brent goes above $125, the refiners make new highs, the Fed hikes, and the 10-year breaks above 5.3%, its high of the past year. Anthropic's IPO window narrows and AI gives back its bounce. Winners: refiners, oil producers, defense, the dollar. Losers: everything priced on distant profits.

The tell: Brent closing above $120.

What would make us tear this up: oil falling and yields rising anyway. That would mean the bond market's worry isn't the war at all but the deficit and the Fed, and the peace trade would be the wrong lens. We'll keep score at the end of December.
