Sahm Rule (real-time) −0.03 +0.07 −0.10 2026-07-01

The curve is quietly re-steepening at both the 2s and the 3s cuts. Credit is unchanged and still parked near the tights. Weekly claims lifted 9k off a very low base. The Sahm real-time reading turned negative, moving further from the 0.5 recession trigger rather than toward it.

§02 · Themes of the week

AI infrastructure is now a power problem, not a chip problem alone

The story shifted this week. Nvidia is looking at a $3 billion investment in SB Energy to underpin an Ohio data centre tied to the OpenAI build-out, while separately trimming its planned OpenAI compute guarantee to below $120 billion. Microsoft's AI plans are being throttled by chip supply, per The Guardian. Reactor 1 at Three Mile Island is being restarted to feed a Microsoft site. Apple is under US pressure to keep Chinese memory chips out of its supply chain during a global memory shortage. Three distinct chokepoints — GPUs, memory, and grid — showed up in the same seven days.

The direction is that the hyperscaler capex cycle is becoming longer and messier, with power supply — not the compute order book — as the binding constraint. Any downstream read on AI-cycle names now has to account for a physical bottleneck that resolves on a multi-year timescale, not a quarterly one.

Counter-thesis: this reads as a capex bull, not a bottleneck. Nvidia trimming the OpenAI guarantee, taking direct exposure to a power developer, and the SK Hynix approval of $38 billion in new memory fabs that won't ship a chip before December 2028 all point to more supply arriving, not scarcity. The squeeze resolves as the money spent this year lands as electrons and wafers in 2028. This would be wrong if Q3 hyperscaler earnings show sequential deceleration in AI-attributable revenue while capex guidance stays flat or rises — the moment the "we're just building ahead" defence stops working.

Trump reopens the Korea file

The White House has asked to scale back US–South Korea joint exercises to preserve Trump's channel to Kim Jong-un. Seoul has responded publicly. Le Monde carried the request; NRK carried Seoul's reply. This lands into a week where Trump-Korea framing dominates the top of the US-tagged headline stack.

The direction is that Northeast Asia alliance risk is edging up again. A visible reduction in the exercise cadence would be the first hard alliance concession since the 2018–19 cycle. Any name whose earnings profile depends on the current US–Korea posture now carries a headline factor that sits outside the AI-cycle narrative.

Counter-thesis: this is a negotiating opener, not a policy. Trump has floated exercise cuts before, walked them back, and the DoD budget line for Pacific posture kept expanding through both terms. Markets have learned to fade the first draft. This would be wrong if the joint communiqué after the next US–Korea principals meeting drops the standard "combined exercises continue at full scope" language — that signals the change has been operationalised, not just floated.

Managed care under sustained fire

UnitedHealth is down 5.1% on the month and 10.3% behind SPY over four weeks, with an RSI of 39 sitting well below sector neighbours. Luigi Mangione will plead guilty on federal charges tied to the killing of the UnitedHealth CEO — a story that keeps reopening the political fight over denial rates and prior authorisation. States take Meta to trial in California this week over social-media harms to children. The through-line is that the political cost of being large, opaque and consumer-facing keeps rising.

The direction is that Healthcare Plans stays a headline-heavy sector with an asymmetric downside case around federal-programme margins.

Counter-thesis: UNH is already discounting a lot. It sits 57% above its 52-week low, has raised its dividend into the drawdown, and has been public about its Medicare Advantage exit strategy. If the political news simply keeps repeating the same beats, the gap between current sentiment and the operating reset gets harder to sustain. This would be wrong if a specific federal reimbursement-rate change lands before year-end that materially shifts the Medicare Advantage margin structure.

The catch ▸ Energy rallied straight through a Presidential wallop

On 3–4 August Trump publicly told Exxon and Chevron they were "making too much money" on the Iran war and should "give some of that back". In the week to 15 August, XLE finished up 7.67% and XOM up 4.61%; XLE is now sitting 2.4% off its 52-week high and 49% above the low. The read: buyback capacity and crude structure are outweighing the rhetoric. That holds until the rhetoric hardens into a specific windfall-tax proposal — at which point the current price stops being a fair estimate of anything.

Ticker Exchange Sector Theme link Snapshot
SPY US ETF Broad market Reference $776.34, RSI 75.1, at 52-week high, +21.7% 1y, above both 200d and 30w MAs
XLK US ETF Technology AI infra beneficiary $190.01, RSI 69.5, +42.0% 1y, +36.5% 6m, near 52-week high
XLE US ETF Energy See The Catch $61.91, RSI 66.2, +7.7% 1w, +47.1% 1y, sector shrugging political pressure
XLY US ETF Consumer discretionary Weakest cyclical $118.20, RSI 75.2 while −1.4% 1w; RSI/return divergence worth watching
AAPL US Technology Chip-supply chokepoint $305.93, −2.3% 1w, RSI 25.8, relative strength −12.4 vs SPY over 4w. Under geopolitical overhang: US pressure to remove Chinese memory chips (WSJ, 15 Aug) plus Alibaba-partnered China AI model. Price action combines a supply-chain overhang with a China-policy signal — two independent factors, not a single cycle read.
MSFT US Technology AI infra $495.40, RSI 84.8, +23.5% 1m, industry trend flagged as peaking. The Guardian carries a chip-shortage overhang; the Three Mile Island restart is tied to one MSFT site. RSI extended enough to matter.
NVDA US Semiconductors AI infra core $225.16, RSI 75.4, industry trend flagged as degrading despite the price level. Material driver: $3bn planned SB Energy stake and OpenAI compute guarantee trimmed to below $120bn (Reuters, WSJ, 15 Aug). Now a proxy for the power side of the trade as much as the GPU side.
META US Communication Services Regulatory read-across $589.85, RSI 48.8, −11.2% 1m, −24.2% 1y, below both 200d and 30w MAs — the only name in this table with both trend filters flipped bearish. Multi-state child-harm trial opens this week in California.
XOM US Energy See The Catch $160.10, +4.6% 1w, +9.7% 1m, industry trend rising. Political overhang: Presidential windfall attack 3–4 Aug. The market has ignored it so far.
