Indexes

September opens on the two arguments August never settled, and both got louder overnight. Crude is higher for a second session after the weekend exchange of fire between American and Iranian forces, and Donald Trump told Fox News that "we're going to hit them hard." Treasury yields, already reset by Friday's Jackson Hole speech, sit on ground the market has not covered since the start of 2025. Stock index contracts are marked lower across the board, with the damage concentrated where long-duration growth and semiconductors overlap.

London reopened after the summer bank holiday into a European session that has drifted lower all morning. Asia split: Seoul added 0.23% and Taipei rose, while Tokyo, Hong Kong, Shanghai and Sydney all finished lower.

SPY, the broad-market fund, daily: Monday's $767.05 close, against $754.36 for the 50-day line.

QQQ, the large-cap technology fund, daily: $716.76, two dollars shy of its 20-day line at $718.78.

In the News

Rates, FX, Commodities

The bond market is doing work that would normally require a data release. Monday's session pushed the ten-year to its highest since the opening weeks of 2025, and it has added a basis point again this morning to trade near 4.76%. The gap from the two-year out to the ten sits around 40 basis points.

Rodrigo Catril of National Australia Bank argues the measured scale of the weekend's exchange suggests neither government wants a sustained war, while stalled talks leave room to escalate. That is why a barrel is up two dollars and not ten.

Technicals

Twenty-five points separate Monday's S&P 500 close of 7,686.14 from a 20-day average of 7,711.30, with the 50-day at 7,563.28 a further 123 points below. The Nasdaq Composite holds the same posture, 26,370.89 against a 20-day of 26,388.00. Small caps are the weak leg: the Russell 2000 at 2,956.45 trades under a 20-day of 3,019.29 and a 50-day of 2,991.78, having given back the 3,000 handle it first reclaimed in June.

Ten-year notes at 4.76% have cleared the 4.63%-to-4.75% band that contained August, so the next reference sits in January 2025 territory rather than anywhere on this summer's chart. Five-year notes at 4.51% are also at their highest since early last year, and that is the part of the curve a policy mistake gets priced into first.

Breakouts

The refiners are the trade this war has been paying, and all three majors enter Tuesday within touching distance of 52-week highs. Valero Energy (VLO) closed at $358.92, less than four dollars under a year high of $362.79 and miles above a 200-day average of $235.03. Marathon Petroleum (MPC) finished at $373.32 against its own high of $376.56. Phillips 66 (PSX) ended at $246.58 with $250.66 the mark to beat. Heating oil has gained 108% in 2026 and gasoline 82%, and processing margins are what turn those figures into earnings.

Valero Energy (VLO), hourly: Monday's $358.92 close sits $3.87 under the 52-week high of $362.79.

Breakdowns

Utilities are the mirror image. The sector fund (XLU) closed at $42.23, below its 20-day of $43.53, its 50-day of $44.64 and its 200-day of $44.70, and only $1.08 above a 52-week low of $41.15 set earlier in the year. A group that competes with a 4.76% Treasury for income did not need a California liability scare on top, and it got one anyway. Marvell Technology (MRVL) is the other name losing ground. Monday's $211.66 close is beneath a 20-day of $225.06 and a 50-day of $226.58, and premarket trade near $205.13 would leave the stock 38% below its year high, with the 200-day at $149.26 the next reference underneath.

The utilities sector fund (XLU), daily: $42.23, with a 52-week low of $41.15 beneath it.

Top Movers

Gainers

Medtronic (MDT), +4.9% to $95.11. The device maker earned $1.45 a share on an adjusted basis against a $1.39 consensus, on fiscal first-quarter revenue of $9.756 billion, up 13.7%. Management raised its full-year organic growth range to 7.25%-7.75% from 6.75%-7.25% and the profit range to $5.94-$6.00 from $5.90-$6.00. The growth line flatters: an extra fiscal week contributed an estimated $570 million. Cardiovascular revenue of $3.927 billion rose 18.9% organically, helped by 88% growth in cardiac ablation.

Diamondback Energy (FANG), +1.9% to $204.27. The Permian producer leads a bid running through the whole exploration group. Devon Energy (DVN), EOG Resources (EOG) and Occidental Petroleum (OXY) are each up about 1.4%. None of it is company news; it is the barrel.

Valero Energy (VLO), +0.9% to $362.01. Refiners get a second reason this morning. The president is due to meet refining executives on Tuesday to discuss pump prices, which have become an awkward number for his party with midterm elections in November. Gasoline futures at $3.09 a gallon are up about 81% this year.

Losers

Marvell Technology (MRVL), -3.1% to $205.13. The custom-silicon designer is the worst of a broad semiconductor markdown, and the Nvidia-MediaTek announcement is the reason to look twice. Marvell was the first of the three companies Nvidia has taken a stake in this year for exactly the custom-accelerator work Marvell sells, and the market is reading a $3.5 billion cheque to a Taiwanese competitor as a comment on how many suppliers that business will support.

Micron Technology (MU), -2.0% to $939.70. Labour unions representing nearly 10,000 of the memory maker's roughly 15,000 workers in Taoyuan and Taichung said on Tuesday they are moving toward a strike unless the company rewrites its bonus scheme, Reuters reported. More than 80% of members who answered an August survey backed the action, mediation is due by mid-September, and the unions point to profit-sharing at Samsung and SK Hynix. Advanced Micro Devices (AMD) is off 1.7% and Nvidia (NVDA) 1.2%.

CrowdStrike (CRWD), -1.9% to $226.73. Monday's 5.77% advance came on partnership announcements at the company's Las Vegas conference, and some of it is being handed back before Palo Alto Networks reports tonight.

MongoDB (MDB), -1.0% to $449.00. The database company reports after the close.

Medtronic (MDT), daily: a 4.8% premarket move takes the stock above a 200-day average of $89.78.

Marvell Technology (MRVL), daily: a $211.66 close leaves $226.58, the 50-day line, overhead.

Key Macro Data Today

Manufacturing gets its national scorecard at 10 a.m. Eastern alongside the first of this week's three labour readings.

July's 55.6 headline was the strongest factory reading since 2022, and a modest step down would surprise nobody. Prices paid carries the weight this morning. It has sat above 70 all summer, crude has now risen for two sessions, and a Fed chair who spent Friday describing 3.7% inflation as work still to be done will read another hot input-cost figure as evidence rather than noise. Job openings matter for the opposite reason: a soft number is the clearest argument left against a September move.

Notable Earnings This Session

Before the open. Medtronic has already reported and is covered above.

After the close. Palo Alto Networks (PANW), Dell Technologies (DELL) and MongoDB (MDB) all report tonight, the first real look at enterprise technology budgets since Nvidia's quarter. Dell decides the mood: its server business has carried the year's argument about whether building artificial-intelligence infrastructure is a profitable enterprise or merely a large one. Palo Alto goes in at $382.13, roughly four percent under a year high of $398.88. Broadcom follows on Wednesday and Zscaler on Thursday.

Drivers

1. The inflation reading inside the manufacturing survey arrives at 10 a.m. Eastern, and the market has organised itself around it. Traders now price roughly 57% odds on a hike this month, up from about 40% a week ago, and the Federal Open Market Committee meets on the sixteenth. A prices-paid figure holding above 71 hands the hawks a second data point to set beside a barrel that has climbed for two sessions.
2. Utilities have lost their bid, and the reason has widened. Monday was about a bill in Sacramento; this morning is about a ten-year note at 4.76% making an ordinary dividend look thin. The sector fund at $42.23 sits a dollar and change off its 52-week low, and the two California names that repriced yesterday still have rating agencies to hear from.
3. Tonight's reports are the first enterprise technology numbers since Nvidia's quarter, and Dell Technologies is the one the market will read hardest. Server margins have been the year's argument, and the stock closed at $456.01 having gone almost nowhere in three weeks. Results land after the 4 p.m. Eastern bell.
