Our forecasting track record

What changed, in plain words

• Shares: The S&P 500 closed at a record 7,736.52, up 1.79%, and the Dow gained 907 points to 54,086. — Two-thirds of American shares rose, not just the big technology names.
• Chips: Korea's main index jumped 4.51% and AMD posted record revenue of 11.5 billion dollars, up 50% — then fell 8.9% after the bell. — The chip complex bounced hard, yet the best chip results of the season were sold anyway.
• SpaceX: SpaceX's first results as a listed company beat on revenue, up 92%, yet the shares fell about 11% before Wednesday's open. — It spent 18.4 billion dollars in three months, and on Thursday early investors may sell for the first time.
• Oil: US crude fell more than 6% to 75.32 dollars a barrel on hopes of a deal to reopen the Strait of Hormuz. — Cheaper oil feeds through to fuel and shipping costs, the most direct link to household prices.
• Interest rates: The US government's thirty-year borrowing cost, 5.23% on Monday, is near its highest since 2007. — Long-term borrowing costs are rising while short-term ones sit still — usually a sign of worry about government debt and inflation.
• Jobs: The July US employment report lands Friday at 8:30am New York time, with forecasters looking for about 120,000 new jobs and unemployment ticking up to 4.3% from 4.2%. — This is the week's one scheduled event that can move interest-rate expectations in either direction.
• Memory chips: Memory prices are still rising, but far more slowly — contract prices are forecast up 13–18% this quarter after rising 58–63% last quarter. — Slowing increases are not falling prices, but they are the first thing you would see if the AI hardware boom were cooling.
• Gold and the dollar: Gold rose about 1% to 4,075 dollars an ounce at the close and traded near 4,096 this morning; silver rose above 59 dollars. — Both keep climbing even on a calm, cheerful day for shares, which is a quiet vote of nervousness underneath a confident market.
• Amazon: Jeff Bezos filed to sell about 15 million Amazon shares worth roughly 4.1 billion dollars, and the shares fell 2.3% on a day the market rose sharply. — Insiders selling is common and not a signal on its own, but this is the second large share-supply event this week alongside the SpaceX unlock.
• Trade: The decision on whether to tariff imported semiconductors, chipmaking equipment and the products containing them was still under review as of Tuesday. — An unresolved decision is a scheduled risk with no date attached, which is why we keep checking rather than reacting.

Headline — a de-escalation record built on broad participation, and an AI complex that sold two clean beats

Tuesday was a genuine risk-appetite advance with better internals than the rally it followed. The S&P 500 closed at a record 7,736.52 (+1.79%, +136.02), the Nasdaq Composite at 26,584.99 (+2.59%) and the Dow at 54,085.88 (+1.71%, +907.47). The catalyst was Treasury Secretary Bessent telling CNBC that the US and Iran could agree as soon as Tuesday or Wednesday to reopen the Strait of Hormuz; WTI fell more than 6% to 75.32 dollars (EVT-0308, EVT-0309). Unlike Monday, participation was wide: technology +4.20% but industrials +3.42%, the Russell 2000 +1.73%, roughly 68% of US issues advancing and 319 S&P members higher, with only energy and utilities lagging. That is a direct, if one-day, disconfirmation of the equity-concentration thesis.

The more interesting signal came after the bell, and it was not about demand. AMD posted record revenue of 11.5bn dollars (+50%), data-centre revenue of 6.7bn (+107%, now 58% of the company), non-GAAP EPS of 1.66 dollars, guided Q3 to 12.7–13.3bn and told investors the data-centre segment should more than double in 2027 — and fell 8.94% after hours to 472.20 (EVT-0313). SpaceX's first public quarter beat on revenue (7.8bn dollars, +92%, versus a 6.8–6.9bn consensus) and on adjusted EBITDA (3.5bn versus 2.0bn expected), carried a 47.5bn dollar backlog and 100bn dollars of cash, and still fell about 11% pre-open Wednesday to about 111.80 after closing Tuesday at 125.33 (+9.4%) (EVT-0311).

The common thread is the financing leg, not the demand leg. SpaceX spent 18.37bn dollars in the quarter, ran a 1.2bn dollar operating loss in its AI segment, and faces a Thursday lockup expiry that JPMorgan says frees 911.5m shares and could raise the public float by 143%. In the same note JPMorgan raised its target to 240 dollars from 225 while projecting capex of nearly 200bn dollars in both 2027 and 2028, which "further pressures free cash flow in 2027, a trend we see across the hyperscalers" (EVT-0312). A sell-side bull explicitly pricing multi-year negative free cash flow across the buildout is the cleanest confirmation of thesis #1 we have logged this month — and it arrived on a day the tape made a record high.

The rates picture is the quiet dissent. FRED's constant-maturity 30-year was 5.27% on 07-31 and 5.23% on 08-03 — the highest since 2007, reached after the Fed held on 07-29 — while the 2-year sat at 4.25% and the 10-year eased to 4.61% at Tuesday's close (EVT-0316). The long end is leading, which is a term-premium and fiscal-supply story rather than a growth-scare story, and it is the one channel in this brief that is deteriorating while everything else improves.

Memory is decelerating, not rolling over. TrendForce has conventional DRAM contract prices up 13–18% quarter on quarter in 3Q26 after 58–63% in 2Q26, with HBM negotiations already shifted to HBM4 for 2027 (EVT-0318). Korea read the rebound, not the deceleration: the KOSPI rose 4.51% to reclaim 6,600, SK hynix +7.10% to 1,689,000 won and Samsung +4.17% to 250,000 won, helped by at least six firms initiating buy or overweight coverage on SK hynix ADRs (EVT-0315).

On Hormuz, the market priced the headline; the text is thinner than the headline. Reporting on 08-05 describes a 60-day ceasefire, an Article 5 committing Iran only to "best efforts" on safe passage for 60 days, Iran and Oman defining the strait's future administration, and Iran insisting it is negotiating solely with Oman on a one-to-three-month arrangement in which it is dominant (EVT-0310). Roughly 2.6 billion barrels of crude have already been disrupted during the war. A temporary, Iran-favourable arrangement re-prices oil down today without removing the chokepoint risk.

Readings

Fact-check log

Standing theses — where the evidence moved

• #1 AI-credit fragility — confirming, and for the first time through the financing leg rather than the demand leg. JPMorgan raised its SpaceX target to 240 dollars while projecting capex of nearly 200bn dollars in both 2027 and 2028 that "further pressures free cash flow in 2027, a trend we see across the hyperscalers" (EVT-0312). SpaceX spent 18.37bn dollars in one quarter with a 1.2bn dollar AI-segment operating loss (EVT-0311). Two clean beats were sold. Disconfirming, and it matters: credit is wide open — high-yield spreads 2.78 percentage points with no widening — and SpaceX holds 100bn dollars of cash against a 47.5bn dollar backlog. This is a fragility that is being financed comfortably, not one that is breaking.
  For your money The risk here is not that AI stops working; it is that the companies building it spend more cash than they earn for years, so their share prices depend on lenders and investors staying willing. This isn't a reason to make a big move — it is a reason to check how much of what you own is the same handful of AI-linked companies, keep money you need within a few years out of them, and avoid borrowing to add more.

  What to watch Matters more if these companies start funding the buildout with new borrowing at rising interest costs, or if the extra interest riskier companies pay begins climbing; matters less while they fund it from cash and profits.
• #5 Sovereign and government-debt stress — confirming, and the only channel deteriorating today. The 30-year Treasury yield at 5.23–5.27% is its highest since 2007, reached after the 29 July Fed hold, with the 2-year at 4.25% and the 10-year easing to 4.61% (EVT-0316). Long-end-led moves are a supply-and-inflation-compensation story, not a growth story, and they sit uncomfortably beside a record equity close.
  For your money Long-term government interest rates are the anchor for mortgage rates and for what your savings must earn to keep their buying power. This isn't a reason to make a big move; it is a reason not to assume borrowing costs fall from here, and to be careful about locking money away for a long time at a rate that only looks generous today.

  What to watch Matters more if long-term rates keep rising while short-term rates hold, or if the same pattern appears in other big governments' bonds; matters less if it reverses on a cooler inflation reading.
• #7 Equity concentration and breadth — disconfirming today. The record was broad: Russell 2000 +1.73%, industrials +3.42% against technology's +4.20%, roughly 68% of US issues advancing and 319 S&P members higher, with only energy and utilities lagging (EVT-0308). One session is not a trend, and the 26 July review already warned that ETF-level breadth measures behave like two or three independent bets, not five hundred. Logged as P-0070 so the claim resolves against reality rather than against our own read.
  For your money A market where many companies rise is less dependent on a few giant ones, which makes an ordinary index fund behave more like the economy and less like a single bet. This isn't a reason to make a big move — a broad day is welcome, not a signal — so keep your savings spread and let a trend prove itself over months.

  What to watch Matters more if equal-weight measures keep pace with the headline index for several weeks; matters less if leadership narrows straight back to the largest technology companies.
• #4 Compute as a strategic resource — decelerating, not rolling over. Conventional DRAM contract prices are forecast up 13–18% this quarter after 58–63% last quarter, with HBM negotiations already on 2027's HBM4 (EVT-0318). Korea traded the rebound: KOSPI +4.51%, SK hynix +7.10%, Samsung +4.17%, with at least six firms initiating buy or overweight coverage on SK hynix ADRs (EVT-0315). Deceleration is the leading edge of the rollover this thesis watches for, but it is not the rollover.
• #6 Energy and critical commodities — disconfirming on price, unresolved on structure. WTI -6%+ to 75.32 dollars on the prospect of Hormuz reopening (EVT-0309), against a reported draft that is a 60-day arrangement with Iran committed only to "best efforts" and Iran and Oman defining the strait's future administration (EVT-0310). About 2.6 billion barrels have already been disrupted. Cheaper oil today; the same chokepoint tomorrow.
• #3 Crypto-to-compute capital rotation — mildly confirming, with a new transmission channel. Bitcoin about 64,487 dollars and Ether about 1,881 dollars failed to keep pace with record equities (EVT-0319). Separately, SpaceX now carries 18,712 bitcoin on a listed balance sheet and took a roughly 195m dollar fair-value hit in the quarter (EVT-0311) — crypto volatility now arrives inside a public company's reported earnings.
• #9 Labour-market deterioration — disconfirming. The deterministic gauge reads calm on both legs: Sahm-rule gap 0.067 percentage points and a four-week claims average of 202,750, 8.9% below the prior four weeks (EVT-0317). Friday's July report is the test; consensus is about +120,000 with unemployment rising to 4.3% (EVT-0320). Logged as P-0072.
• #2 parallel payment rails and #8 the consulting and IT-services value chain — no new evidence today. Neither is retired; neither moved. The Section 232 semiconductor decision remains pending (EVT-0321), which is a policy risk with no date attached rather than a development.

On the radar (monitored, never traded)

• CAT — material signal. Caterpillar reported adjusted EPS of 8.17 dollars against 4.72 a year earlier and a 6.20 consensus, with sales up 24% to 20.5bn dollars — the first quarter above 20bn in company history — and closed up 5.60% (EVT-0314). CAT sits on the radar as the AI-buildout builders-and-equipment proxy; a record quarter says the physical leg of the buildout is accelerating even as its financing leg draws scrutiny.
• XLY (consumer demand) — split signal. Wayfair +19% on a beat against Aptiv -15.5% on weak guidance and a large sequential revenue decline; NRG -10% and Rockwell -6.4% on mixed results. The consumer-demand lane is not deteriorating uniformly.
• SMH / ASML (semiconductor complex) — rebound. The Korea move (KOSPI +4.51%, SK hynix +7.10%) and AMD's 107% data-centre growth both cut against last month's chip-selloff narrative; AMD's after-hours fall does not.
• LQD / TIP (credit and inflation-compensation sensors) — the row to watch. With the 30-year at a 19-year high while high-yield spreads sit at 2.78 percentage points, the deterioration is in duration, not in default risk. These two sensors, not the credit gauge, are where that would show up first.
• No radar additions or retirements proposed from this run — promoting a radar name to the traded universe stays a human-gated step.
