The world index closed at a record, the yen re-crossed its wire, and the belly of the curve failed a fourth time — all three of last week’s levels were answered in one week, by a jobs report three times the consensus. Sideways ended. The tape now has to decide whether it likes the reason.
1 · This Week’s Action
The global view. The ex-US world index closed the week at 86.41, up 1.15% — a new record close, above the 86.08 mark this letter set last Saturday as the confirmation line. It did not get there in a straight line. Monday closed 85.25, Tuesday 84.65 — under the 85.23 support on a daily close, the deepest dent in four weeks — and then three green sessions: 85.13, 85.95, 86.41. Three weeks of triggering marks in both directions and resolving nothing on the weekly close ended with a weekly close that resolved the upper one. The all-world index closed 161.73, up 0.45%, sixty-six cents under its August 13 record; the S&P gained 0.11%, the Nasdaq 100 0.35%.
The year’s order held and widened. VEU +17.5% for 2026, VT +14.7%, the S&P +12.9% — the ex-US lead over America is back to 4.5 points, from 3.3 last week, because this was a week the world carried. It is the first go-global week in three.
Korea is where the confirmation extended — and it came with the Friday number. Last Saturday this letter recorded the weekly close above 180 as the confirmation of the July breakout and set the new frame: hold above 180 on the weekly closes, 183.46 the week’s high water, 190.11 the sidecar-day cap. The fund closed Friday at 188.87, up 4.81% on the week — through the high-water mark, a dollar and a quarter under the cap — after a week that dipped to 175.80 on Tuesday’s close, under 180, and then recovered every session: 178.86, 180.56, 188.87. Friday alone was worth 4.6%. It is +94.3% on the year in dollars. The Tuesday close under the line and the Friday close over the cap are the same story: the week’s global bid was written on Friday morning at 08:30 in Washington, and the corridor was the place it landed hardest.
Behind it the whole regional board went broad. Last week’s ten green of thirty-five became twenty-eight green of seven red — the fourth breadth flip in five weeks (broad in July, narrow into August 15, broad on August 22, narrow on August 29, broad now). The leaders: Brazil +6.50% led the board, Korea +4.81%, Taiwan +3.97%, Poland +3.77%, Indonesia +3.16% — the corridor and the commodity periphery green at the same time, which has not happened since July. The losers were all one continent: Germany −1.57% the worst line, France −1.10%, the Euro Stoxx 50 −0.99%, Switzerland and EAFE growth the only other red lines among the majors. The best-to-worst spread widened to 8.07 points from 6.75 — a board that broadens while its spread widens is dispersing again, not rotating in place. That is the first structural change in the regional read in a month.
The cross-asset backdrop — the barrel, and then everything else. USO +9.45% was the board’s leader by a distance, and the reason sits in section 2: oil went from 83 to above 91 after the US and Iran exchanged fire on Tuesday and two tankers were reported hit near Hormuz. The bitcoin fund +3.03% was second, the top-20 and top-30 lines +1.22% and +1.13% third and fourth. The bottom: copper miners −3.98%, the long bond −0.81%, the belly −0.65%, gold −0.52%, the dollar −0.35%. Six green, six red. The oil line and the copper line pointing in opposite directions in the same week is the board’s own diagnosis: a supply shock, not a growth signal — the metal that prices growth was sold, the commodity that prices a strait was bought. And the two duration lines, IEF and TLT, red together on a week the dollar also fell: the funding tells this letter tracks did not rotate, they hardened.
The US sectors. Four of eleven closed green and financials closed flat to the cent: energy +2.20%, technology +0.86%, utilities +0.82%, health care +0.17%. The bottom: consumer discretionary −1.96%, materials −1.39%, real estate −1.24%, industrials −1.06%, staples −1.02%. Not the full inversion of the previous two weeks — technology stayed green from last week’s top three, communications fell out of it — but a specific shape: the two rate-sensitive groups (real estate, discretionary) and the two commodity-input groups (materials, industrials) at the bottom, the barrel and the chips at the top. Sunday’s letter owns the tape beneath it; the geography is that Friday’s jobs number sorted the sectors by their sensitivity to the discount rate, and the sort held through the close.
The tech ETFs — the split flipped back. Two Fridays ago this letter named the split — semis down, software up — and last week called it a rotation with a direction inside the stack. This week the direction reversed: thirteen green lines of twenty-one, led by silicon and crypto — digital assets +7.45%, WisdomTree AI +3.20%, SMH +2.51%, XSD +1.99%, ARK +1.93%, the fabless vehicle +1.57% — and the red eight are the layer above the chip, in the exact order it led last week: defense tech −4.85%, software −4.50% (the board’s worst after two weeks as its best), cybersecurity −4.03%, cloud −3.64%. The software-to-semis ratio that bottomed on June 22 and had risen 52% off that low gave back a full week of it on Friday alone; the pair monitor reads the spread at 1.1 standard deviations, closing. Two weeks of software over silicon, one week of silicon over software, and both on the same one-week cadence as every other board. The difference this time is that the reversal has a macro cause with a date on it: payrolls at 08:30 ET on September 4, a duration repricing that hit the long-dated cash flows of software and handed the order book to the cyclical end of the chip complex.
The global sectors. Seven green of twelve, and the top three are the same three that led the US: energy +2.29%, technology +1.65%, financials +1.23%. The detail that matters most is the one this letter has tracked as the tape’s decider for three editions: global financials closed Thursday at 137.00 — a new record — after sitting 0.38% under the old one a week ago, “one green day away.” It got the green day on Wednesday and Thursday, and gave back 0.6% on Friday to 136.20. Recorded, then eased — the same shape as materials two weeks ago, which set its record and un-cleared its February line within five sessions. Materials this week: −0.69% to 115.29, under the 116.54 February line for a second week, with copper miners −3.98% underneath it. The bottom of the global board: consumer discretionary −1.77%, industrials −1.15%, REITs −1.01%.
Was the sector week global, or one region carrying the average? The house Sector Engine decomposes each of the eleven sectors into its four regional legs, and this week’s answer inverts last week’s: emerging markets were the greenest column on the board — every one of the eleven EM cells green (tech +3.4%, energy +2.1%, industrials +2.0%) — while Asia-Pacific developed was red in eight of eleven (tech −2.4%, materials −3.0%, real estate −2.8%; utilities +5.4% the lone strong cell). Tech was green in three regions of four and red only in Japan-proxied developed Asia. And the sharpest single split, once more, is energy — but with the sign flipped from last week: the US cut rose 2.2% while Europe’s energy fell 3.1%, because the global vehicle is where the US barrel lives and the European vehicle is where the European refiner lives. Last week Europe’s energy rose while the global cut fell; this week the exact reverse. The barrel moves; the two wrappers take turns being the one that owns it.
The Global Compass
Regions: the corridor led for a second week — with the periphery alongside this time. Emerging beat developed a third straight week (VWO +1.07% against VEA +0.96%), but the composition changed again: the corridor (Korea, Taiwan, Japan all green, Korea the second-best line on the whole board) and the commodity periphery (Brazil, Poland, Indonesia, Argentina, Norway) rose together, while the developed core of Europe fell. Two weeks ago the EM bid was China and the periphery with the corridor resting; last week it was the corridor with China soft; this week it is both, with Germany and France the only large markets sold. The read this letter has carried — the AI-supply-chain bid is cyclical inside a broadening market — got its clearest single-week demonstration of the summer: a stronger-than-expected US economy is a bigger order book for the corridor, and a higher oil price is a better week for the exporters. Both landed on Friday.
Sectors: risk-on in the emerging column, risk-off in developed Asia, mixed at home. The engine’s cyclical-defensive spreads give the rotation its regime reading by region: EM +0.7% and Europe +0.4% cyclicals over defensives; the US −0.7% — both sides down, cyclicals more — and Asia-Pacific developed −2.2%, the only region where the defensives clearly out-held the cyclicals. That is the week’s most awkward internal: the region whose country funds led the board in dollars (Japan +2.51%) is the region whose local sector cut read defensive. The reconciliation is the yen: three days of yen strength from 160 to 156 flattered every dollar wrapper on Japan while the Tokyo tape itself rotated toward safety. Section 7 takes that apart.
Sectors: the leaders’ bench cleared a line and kept it — for a day. Three weeks of materials read led, lagged, led-to-a-new-high, then cleared-and-un-cleared. This week financials joined the pattern: the record this letter said was “one green day away” arrived on Thursday at 137.00 and eased to 136.20 by Friday. Technology rose 1.65% and remains 4.6% under its June high; energy is its own story, the barrel +105% on the year and the sector +39%; industrials fell 1.15% and sits 4.6% under its August high. A board where the closest challenger takes its record and gives back half a percent the next day is a board that can clear lines. Whether it can hold them is still the open question, and it has been open since materials first asked it three weeks ago.
Stay home vs go global — the US view. The world won the week: VEU +1.15%, VT +0.45%, SPY +0.11% — the first go-global week in three, and it came with the record. The year reads the same way and wider: +17.5% against +14.7% against +12.9%, ex-US ahead by 4.5 points, from 3.3. Both readings, both honest: the trend is intact, and this week it was being sanded back up rather than down. The weekly closes on VEU’s new board — 86.41 the record, 86.08 the old one below it, 85.23 the support that was dented on Tuesday and held on the week — are the levels that say which one is the signal.
Stay home vs go global — the Europe view: the mask flipped a third time. Two weeks ago the euro was bid and the dollar wrapper rose while every European index fell. Last week the euro gave it back and the hedged wrapper beat the unhedged. This week the mask reversed again: the dollar-listed Europe fund fell 0.26% while the euro-hedged wrapper fell 0.87% — the currency was the better half, the equities the worse. Underneath, the exception of last week became the casualty of this one: Germany, which closed the prior Friday at a 52-week high, was the worst line on the whole regional board at −1.57%, France −1.10%, the Euro Stoxx 50 −0.99%; the UK +0.08% and Spain +0.64% the continent’s only green large lines. And the bond market agreed with the order, loudly: the Bund’s ten-year yield traded 3.36% on Tuesday, a level last seen in April 2011, and 3.38% on Wednesday, while France still borrowed dearer than Italy at ten years — 4.21% against 4.14% — and the gap widened to six basis points from four tenths of one. The continent’s two core markets are pointing in the same direction now. Down.
Stay home vs go global — the Asia view: the corridor answered twice. Last week’s question was whether the confirmation, delivered by the won, would hold. The week answered in two halves. Tuesday: Korea closed 175.80, under the 180 line — the Tuesday of the yen through 160 and the bond rout’s second day, the 1997 transmission channel this letter flagged as “not an abstraction” doing exactly what it does. Friday: 188.87, through the 183.46 high-water mark and within $1.24 of the 190.11 sidecar cap. Taiwan +3.97% to 112.18 — a new 52-week high; Japan +2.51% to 98.28, nineteen cents under its August record. The corridor took the Tuesday hit and delivered the Friday recovery, and the Friday recovery had a macro cause in Washington and a currency cause in Tokyo. The re-rating question from July stays answered as far as price can answer it; the new asterisk is that the answer now depends on a US jobs number and a yen that moved four figures in four days.
The engine’s Asia AI spreads put numbers on the corridor’s internal order, and the order reversed: Korea over Taiwan +0.8% on the week — memory leading logic, after last week’s logic-over-memory +2.4% — and Korea +2.3% over global semis for a second week. The memory vehicle itself, DRAM, rose 6.91% to 59.69, through the 58 line it lived under all of last week. Memory diverging from its own region’s confirmation was the corridor’s internal contradiction to watch; this week the contradiction closed, in memory’s favour.
Stay tech vs go broad. Tech led, narrowly at home and clearly abroad. The Nasdaq 100 +0.35% against the S&P’s +0.11%; global tech +1.65% against the world’s +0.45%. Technology the second-best US sector and the second-best global sector; the semis the best tech lines, software the worst. Tech led this week the way it led in the first half of the year — by its silicon — and the aggregate went positive because the chips outweighed the code. The reverse of last week’s internal rotation, same aggregate direction.
Momentum vs defensive — both ends rose, and the pattern held. International min-vol printed a new high on Thursday at 95.16 and faded to 94.78 by Friday, +1.04% on the week — the third consecutive week the defensive end has made a high and not held it into the close. Global min-vol did the identical thing: 128.22 Thursday, a new high, 127.51 Friday, +0.09%. International momentum rose 1.76% to 54.26 — thirty-eight cents under the failed August breakout at 54.64, a fourth week below it but the closest it has been. So the defensive end keeps making highs and giving them back, and the aggressive end keeps approaching its line and not taking it — the same postponement shape, now on a week the world index itself did resolve. On the year momentum still leads min-vol +13.1% against +9.9%; the regime is intact and, for once, the week went with it.
One more pair, awake again. EAFE value +1.49% against EAFE growth −0.38% — value led by nearly two points after last week’s dead heat, and it led on the week the corridor and the commodity periphery carried the board. On the year value keeps the argument, +16.2% against +9.3%. Last week both factor pairs flattened and the rotation ran through groups, not styles. This week both pairs moved and moved the same way — momentum up, value up, min-vol up but fading — which says the money changed risk appetite and neighborhoods at once. That is what a repricing looks like, as opposed to a rotation.
The Closelook letters — where this one sits. The house thesis, compressed: the stock market is a growing system at the aggregate level in which most constituents slowly fade while a small group massively outperforms — and that group changes dynamically; it never stays static. Own the aggregate, know the current winner group, watch for the rotation. Right now the winner group is the AI stack, and the live question is which of its layers — building, operating, using — earns the next leg. Three letters read that question at three altitudes: Closelook@Global Stock Markets (Saturdays) follows the geography of the money — regions, cross-asset, the core thesis owned through ETFs. Closelook@US Stock Markets (Sundays) reads the tape — the four-layer AI thesis at sector and index degree, the levels, the print records. Closelook@Hypergrowth (Sundays) reads the names — four growth buckets, the flow ledger, the tactical sleeve. Same market, top down. This is the map altitude.
2 · The State
The mechanism, named: a repricing of time, delivered by a jobs report. Put the week in order. Monday and Tuesday belonged to the bond market — Japan’s ten-year closed above 3% on Tuesday for the first time since 1996, the Bund touched its highest since April 2011, the US ten-year ran six straight rising sessions back to its January-2025 prints, and dollar-yen crossed 160 overnight. Wednesday the US ten-year touched 4.81%, its highest since November 2023, and oil went above $90 after the US and Iran exchanged fire and two tankers were reported hit near Hormuz. Thursday the tape had its best day in a month, Waller cut the hike odds to a coin flip, and the yen was already back at 157. Friday, at 08:30 in Washington: payrolls +162,000 against a consensus near 53,000, with 55,000 of upward revisions, unemployment 4.1%, participation 61.6% — the first jobs report of the Warsh Fed, three times the number. The two-year yield jumped to 4.43%; hike odds for September 16 went back above 58%; and the market re-priced duration in one session. The long-dated cash flows lost: gold −1.2% on the day, bitcoin −2%, software −2%, Apple and Microsoft the weakest shares in the Dow. The order book won: chips +3%, Nvidia and Caterpillar the strongest Dow shares, Korea +4.6% in a session. The honest name for the week is not sideways any more. It is a market that was handed a reason and moved on it.
What did choose: two of the quiet tells, in opposite directions. The bond market first. IEF spent the week entirely under the reclaim line — 92.74, 92.10, 92.18, 92.28, 92.25 — never approaching 93.17, and printing 92.10 on Tuesday, a new low for the year. That is the fourth consecutive failed weekly reclaim, and the first of the four that did not even attempt one: three failures from ascending midweek pushes, and then a week with no push at all. TLT held its own floor at 81.2 (82.21, −0.81%, low 81.87 Tuesday). The structure stands — the long bond holds, the belly refuses — and the house’s bond veto over the equity read stays engaged, now on a week the equity read gave its confirmation. Then the yen, which chose the other way. Dollar-yen crossed 160 overnight into Tuesday — through the 159.5 wire, the door this letter had watched since July’s record intervention, on the exact day Morgan Stanley’s desk noted that more than half the intervention’s effect had already faded. Then Bank of Japan board member Hajime Takata said hikes may need to become “continuous” rather than twice a year, and the yen ran three days: 159 Wednesday, 157 Thursday, 156 Friday — its strongest three-day run since the July intervention, and back under the wire it had just broken. Two tells, two directions: the belly of the US curve hardened against the bull, and the funding currency of the carry loop reversed in the bull’s favour. Last week both chose against. This week they split.
The podium turned, twice, and the tape heard both. Thursday: Christopher Waller cut the September hike odds to a coin flip, the ten-year eased, the dollar fell a third day, gold and oil rose. Friday: the number. The reading the previous edition carried as the central tension — hard assets priced for an easing cycle against a central bank leaning hawkish — resolved for a second week in the hawks’ favour, and this time the resolution was the data rather than the podium: gold −0.52% on the week with Friday its worst session, the miners sold, silver −0.33%, the dollar index near 99 after three losing days into the number and then bid on it. Gold spent Tuesday under $400 on the fund and reclaimed it Thursday at 410.22 before Friday took it back to 406.77. Bitcoin +3.96% on the week to a Thursday bar at 81,272 and 80,913 Friday — the coin’s highest close in almost four months, and still inside the 77,000–83,000 zone it has not left. The same input, the same trade, two different scorecards: the metal fell, the coin rose, and neither left its range.
One session, and the pattern with a memory inside it — again. Last week this letter noted that Warsh’s keynote got exactly one session of market time, and that inside that session the old-guard megacaps caught the bid against the day while the capital-hungry end of the AI trade was sold. Friday produced the mirror image with the same discount-rate logic: a hot number, a hike more probable, and this time the balance-sheet giants were the casualties (Apple, Microsoft the weakest in the Dow) while the cyclical end of the same trade — chips, industrials, the corridor — was the winner. Both sessions are the same rhyme with the sign flipped on the growth term: when the discount rate leans up on a policy signal, the market buys duration-light quality; when it leans up on a growth signal, the market buys the order book. One Friday is one Friday. It is also the second time in two weeks the tape has told us it is sorting by duration.
The two hard-asset charts, read the house way. Gold: the impulse out of the consolidation stalled again, this time from below — the fund closed the week at 406.77, printed 396.75 on Tuesday, and never re-approached the August highs. The 4,400 spot falsifier from the last two editions is not on this week’s data sheet — the spot series was not pulled — so this letter records the fund’s levels and lets the count wait a week: 396.75 is the number to hold, 410.22 the number to clear. Bitcoin: the coin spent the entire week inside the 77,000–83,000 zone for a second week — 77,300 Wednesday, 81,272 Thursday, 80,913 Friday — and the fund closed at 45.23, above both the 44 and 44.5 lines it lost on the previous Friday, with a 46.35 print on Thursday. Last week both hedges stood at their falsifiers; this week one reclaimed its lines and the other made a lower low. The pair ratio that had pushed to the bottom of its post-February range kept going: inside the duration repricing, the crypto leg held better than the metal for a second week.
Seoul: the certificate held, and then it was rewritten. The buyback-session low was never revisited, and the Tuesday close under 180 (175.80) lasted one day. The fund walked 180.86 → 175.80 → 178.86 → 180.56 → 188.87 and closed the week through the 183.46 high water. The structural read from three weeks ago — breakout, consolidation above the broken channel, completed double bottom, resistance at 180 — now has its confirmation candle and its first held week, with the cap at 190.11 as the next line. What it also has is a currency it cannot control on either side: last week the won wrote the confirmation, this week the yen’s reversal and a US jobs number wrote the extension. The corridor’s certificate is genuine. It is co-signed.
Europe, two machines, one week on — and the weighing machine moved. The voting machine sold the core: Frankfurt gave back its new high, Paris fell, the Euro Stoxx 50 fell, and the euro was bid, so the dollar wrappers fell less than the hedged ones. The weighing machine, which barely moved last week, moved this week: France 4.207%, Italy 4.144% — the inversion held a third week and the gap widened to six basis points from four tenths. The Bund at 3.354% on Friday from 3.296% the week before; the German ten-year up 19 basis points in twenty-one days. And the sovereign board’s own composite turned back up: SPI +0.43 from +0.35, with the twenty-one-day baseline at −0.08 — the pressure re-heating, and led this time by the ten-year leg (z-score 0.85) rather than the long end. But the direction inside it swapped hemispheres for a second time: last week the US long end rallied and Japan’s sold; this week the US thirty-year sold back to 5.247% from 5.207% while Japan’s thirty-year rallied fifteen basis points to 3.970% from its 4.125% era high — the same week the yen recovered four figures. One sovereign complex inhaling, the other exhaling, and they have now swapped roles two weeks running. The Atlantic has the pressure again.
The macro print. Friday’s payrolls belong to Sunday’s letter in their print-record detail; their geography belongs here, and it was global inside one session. A US number three times the consensus lifted Korea 4.6%, Taiwan 1.9%, Brazil’s fund to the top of the regional board and the corridor’s memory vehicle 6.6% on the day — and sold Germany, France, the software complex and both hedges. The bar has moved again, in the other direction from last week: a fortnight ago the market would not pay for good prints; this week it paid for a good macro number, and paid the cyclical end of every board for it. A market that will not pay for beats but will pay for growth data is telling you where its risk sits: not in the companies, in the discount rate. Section 6 says what follows if the CPI on Friday disagrees.
Hold both halves. The equity boards resolved upward — the world index at a record, financials at a record, the corridor through its high water, breadth back to twenty-eight of thirty-five. The funding tells split — the belly of the US curve hardened for a fourth week, the yen reversed in the bull’s favour, the Atlantic sovereigns re-heated while the Pacific cooled. Sideways is over. What replaced it is a bull market that was confirmed by a tightening impulse, and that is a specific kind of confirmation.
The structural read — the wave count, five years up. Zoom out and the record changes the count’s status without changing the count. From the October 2022 low the house count on the world ex-US reads waves 1 and 2 complete and wave 3 still progressing — price riding the upper half of a four-year channel, and this week’s 86.41 is a new high inside an advance whose projection runs higher. On this count the three-week postponement was a pause in a third wave, and the record close is the pause ending as a third wave should end it: on a breadth flip to broad, with value and momentum both rising. The count keeps its own falsifier — it fails at the channel, not at the record shelf — and the section-4 ladder marks where that argument would begin. The September base case this letter stated last week, about five percent of consolidation, has not been withdrawn by one record close; it has been made harder to reach. Probability, not prophecy.
3 · The Outlook
The three-index read — the money went back up the stack, into the layer that builds. We read the three together because they are three stages of one spend: capex (Rubin Build-Out, what gets built), opex (Agentic Ecosystem, what it costs to run), applications (Agentic Winners, what gets sold on top).
Capex +0.40% on the week — the only green line of the four — and +88.1% on the year. Opex −2.39% and +57.1%. Applications −2.30% and −2.4%. The order of the last two weeks, money leaving the building layer for the selling layer, reversed in one session: the buildout index closed Friday at 1,933.47 after a 2.5% day, from 1,886 on Thursday, while both lighter layers closed the week lower than they started it. Inside the week the buildout was the worst of the three through Wednesday and the best by Friday. That is Friday’s duration split rendered in the house’s own instruments.
The control group agreed with the stack this time — and that is the week’s most important internal. Last week HALO — our growth index carrying no AI thesis — fell 2.25% while applications rose 4.68%: an AI bid inside a growth sell. This week HALO fell 2.02% while applications fell 2.30% and opex 2.39% — the AI stack’s two lighter layers moved with growth, not against it, and only the physical layer separated from the pack. Put the three weeks together: AI unwind inside a flat growth tape, then AI bid inside a growth sell, then growth sell with the AI stack inside it and capex alone outside. The oscillation between “the AI stack” and “everything else” that ran on a one-week cadence has been replaced, at least for one week, by a sort that runs through the stack itself: physical over digital. Inside HALO the week was broad and red — 4 of 23 sub-indices green — with Latin America +2.18%, space +2.08% and longevity +1.80% the exceptions and the destination economy −6.27%, autonomous defense −5.84% and med-devices −3.96% the casualties.
Read the three windows together, because the disagreement is still the signal. On the year capex leads and it is not close: +88.1% against +57.1% against −2.4%. On the month the inversion holds: applications +12.6%, opex +3.2%, capex −2.9%. On the week, the year’s order is back: capex first. Every window now points a different way — the year to the builder, the month to the seller, the week to the builder again — which is what a leadership handoff looks like when it is being contested rather than completed. The tilt this letter announced four weeks ago toward the lighter layers was wrong one week, right the next, and this week it was Friday’s casualty.
The correction lows, re-measured. Applications — which bottomed first, on July 23 — is now +29.3% off its low, from +32.3% a week ago. Capex, off its July 29 low, rose to +13.2% from +12.6%; opex slipped to +14.3% from +17.0%. The spring pattern — the index that bottoms first goes on to lead — is now four weeks confirmed and one week dented. Probability, not prophecy.
The structural line moved the other way. Applications closed 5.3% below its January high — from 3.05% below a week ago; it gave back most of the gap it had recovered. Opex sits 8.1% below its August 13 high, from 5.8%. Capex remains 22.0% below June — from 22.4%, the only layer whose distance to its peak shrank this week, by a hair. The layer that was one ordinary week from going green on the year is now 2.4% under it.
Inside capex: the fab floor lit up, the design lane went dark. The best line in the buildout was storage, +11.04% on the week and +357% on the year, then AI factory systems +5.51%, DC power +5.17%, the AI factory layer +4.93%, thermal +4.79% — the physical plant of the buildout, the racks, the power, the cooling, the drives. The bottom is last week’s top, inverted: EDA and chip IP −7.76% — the design-software lane that led the buildout last week at +5.98% — high-speed interconnects −6.12%, wafer processing −4.94%, design −2.15%. The software of the buildout was sold with the rest of software; the hardware of the buildout was bought with the rest of hardware. And the sharpest reversal on any board a week ago reversed again: HBM memory, last week’s worst at −4.01%, rose 2.83% in the week the corridor’s memory vehicle cleared its line. Twenty-two of thirty-six sub-indices green; the buildout’s breadth was the best in the family.
Inside opex: the compute got bought, the code got sold. The only clear green line was compute operators +3.69% — the layer that owns the machines — with Asia’s constituents +2.20% behind it. The bottom: operations and observability −7.93% — the best sub-index across all four families last week at +5.84% — edge and distribution −3.99%, data and memory −3.82%, govern and secure −3.62%, execution −3.39%. Four of fourteen green. The layer that runs AI split exactly the way tech did, and exactly the reverse of last week: the compute was bought, the code was sold. Foundation models −1.39%, still +712% on the year.
Inside applications: only the two edges held. Two of nine sub-indices green — Asia’s constituents +0.95% and the megacap gateway +0.61%, still the only sub-index positive on the year at +11.2%. The bottom: control plane −4.36%, Europe’s constituents −4.36%, the US constituents −2.95%, enterprise −2.89%, application leaders −2.68%. Last week every sub-index in the layer was green and this letter wrote “no rotation inside the layer; the whole layer was bought.” This week the whole layer was sold except its Asian and megacap edges — which is the same duration sort, applied to the applications layer: the two sub-indices that survived are the two with the shortest-dated cash flows.
The regime gauge. The Money Temperature instrument board closed the week at 55 — down two from 57 a week ago, but up six from the 49 it printed on Wednesday and Thursday, with the regime read “Risk-on rally” at high confidence. The spread underneath is the week in one line: risk appetite +28 and speculation +9, duration −28. Money moved into equities and out of long bonds at the same time. Equities went up, hard assets fell, and the gauge cooled into the middle of the week before warming on the number: the appetite the board reads is the rotation itself, and this week the rotation had a direction.
