AI Trade — Chips −5.6%, Software +5%, SoftBank Bounces

AI trade — sellers of compute sold, buyers bought: chips −5.6%, software +5%, SoftBank +7% in Tokyo

The market took one session to decide what a slower frontier is worth, and its answer was a split, not a sale. On the side that sells compute, the semiconductor ETF fell 5.6% to $497.40, through the $505 line and below Thursday’s $517.43, with Nvidia −3.4%, AMD −4.4%, Micron −5.3% and SanDisk −5.0%; the Rubin build-out index lost 5.3% with all eight layers red, and the interconnect, data-centre power and equipment groups fell 7% to 8.5%. On the side that buys compute, the software ETF rose 5.0% to $106.64, its best day of the year; Zscaler +16.5%, SentinelOne +14.5%, CrowdStrike +13.9%, Palo Alto +13.1%; Microsoft +2.0%, Alphabet +3.2%, Meta +2.7%. The S&P 500 closed $760.88, −0.4%, the Nasdaq-100 $709.18, −0.8%, the Dow −0.2%: the index barely moved because the two halves of the trade cancelled.

The rest of the tape said the same thing in other words. The 10-year Treasury touched 5.00% during the session, the first time since October 2023, and closed 4.975%; it is 4.96% this morning with the 30-year at 5.33%. Brent is $107.34, up 1.6% overnight after the Oman talks were postponed, WTI $103.27. The dollar index is 99.6, gold $4,338, bitcoin $77,400. The Empire State survey printed −8.7 against a forecast near +15, with new orders at −19.6. Europe fell with its chip names — Euro Stoxx 50 −1.0%, DAX −0.5% — while London rose 0.4%. Volatility closed 17.1, up 8%.

Asia is quieter this morning than it was on Monday. The Kospi is −1.2% at 6,604 after Monday’s −3.3%, SK Hynix −0.9%, Samsung −0.7%; TSMC is unchanged at NT$2,380 and the Taiex closed −0.7%; the Nikkei is −0.5% at 63,196 with Advantest −4.0% and Tokyo Electron −1.2%, and SoftBank has bounced 7.2% to ¥6,262 after Monday’s 11.3% fall. China’s August data showed factory output growth quickening while retail sales slowed and missed, and the investment slump deepened. US stock futures are down 0.4% to 0.5%. Today the Fed’s two-day meeting begins, with a quarter-point increase priced at roughly four in five, and Oracle and Adobe are scored at the close: Oracle $144.79 is below its $148.35 sold line, Adobe $265.60 above its $256.29 paid line.

  1. The sort: chips −5.6% to $497.40 through the $505 line, software +5.0% to $106.64 on its best day of the year, security +13% to 17% — S&P 500 −0.4% to $760.88, Nasdaq-100 −0.8% to $709.18, Dow −0.2%, Russell −0.3%; volatility 17.1
  2. Asia, the morning after: Kospi −1.2% to 6,604, SK Hynix −0.9%, Samsung −0.7%; TSMC unchanged at NT$2,380, Taiex −0.7%, MediaTek −2.0%, Alchip −6.4%; Nikkei −0.5% to 63,196, Advantest −4.0%, Tokyo Electron −1.2% — and SoftBank +7.2% after Monday’s −11.3%
  3. Rates and oil into the Fed: the 10-year touched 5.00% on Monday, first since October 2023, and is 4.96% this morning; the 30-year 5.33%; Brent $107.34, +1.6% overnight, WTI $103.27; dollar 99.6; gold $4,338; Empire State −8.7 with new orders −19.6
  4. The $505 line is gone: semiconductor ETF $497.40, below Thursday’s $517.43 and 6.4% under its 50-day at $531.52; memory and storage led on the way down again — Micron −5.3%, SanDisk −5.0%; Corning −13.7%, Teradyne −13.3%, Coherent −12.7%, MACOM −12.8% inside Rubin
  5. Our indices on Monday’s closes: Rubin −5.3% to 1,859.75 with all eight layers red, US −7.0%, Europe −7.9%, Japan −0.5%; HALO flat at 1,019.69; AW40 +4.0% to 946.64 on its applications layer +5.8%; the agentic ecosystem +4.3% to 1,597.67 on security +11.9%; Euro-AI −2.1%, its chips −6.9%, its enterprise software +5.5%
  6. Print record, the night before: Oracle $144.79, 5.3% under its $152.94 entry and below the $148.35 sold line; Adobe $265.60, +6.7% from $248.83 and above the $256.29 paid line — both scored at tonight’s close, the third session after their prints
  7. Outside view: the weekend’s essay is being sorted into winners and losers rather than sold — Monday’s press ran ‘Investors Are Sorting the Winners and Losers From an AI Slowdown’ beside ‘Talk of AI Pause Slams Nvidia, AMD and Intel’; Microsoft, Alphabet and Meta rose while Nvidia fell
  8. China, for the record: August factory output growth quickened while retail sales slowed and missed, and the investment slump deepened — CSI 300 −0.3%, Hang Seng −0.6%; Japan’s tax-cut outline sidesteps its funding, the yen 154.9
  9. Cross-asset check: the Magnificent Seven fund $70.10, above its 69.5 line; volatility 17.1, up 8%; the equal-weight agentic winners +4.0% against the physical layer −5.3%, a nine-point gap between our two US layers in one day; futures −0.4% to −0.5%
  10. The clock: the Fed’s two-day meeting begins today, a hike priced at about four in five; Oracle and Adobe scored at the close; Taiwan’s August revenues this week; retail sales 12:30 UTC Wednesday, the decision 18:00 UTC, the press conference 18:30; Bank of Japan Thursday and Friday; quarterly expiry Friday — and the levels: $757.83, $708.69, $517.43, $505 lost, 5.00%, 6,600
  1. The sort: chips −5.6% to $497.40 through the $505 line, software +5.0% to $106.64 on its best day of the year, security +13% to 17% — S&P 500 −0.4% to $760.88, Nasdaq-100 −0.8% to $709.18, Dow −0.2%, Russell −0.3%; volatility 17.1

    What
    Monday was the first session after the weekend on which the three frontier labs asked, together, for a slower frontier, and the market read the essay the way we suggested it would on Monday morning: as a statement about how much compute gets bought and how fast, not as a statement about whether AI gets used. The names that sell compute were sold — the semiconductor ETF −5.6% to $497.40, Nvidia −3.4% to $210.96, AMD −4.4% to $493.41, Micron −5.3% to $924.03, SanDisk −5.0% to $1,551.99 — and the names that buy it, or that sell what runs on it, were bought: the software ETF +5.0% to $106.64, Microsoft +2.0% to $505.41, Alphabet +3.2% to $349.39, Meta +2.7% to $665.60. The security names that Sunday’s Weekly Signal identified as beneficiaries of the next model generation had their day: Zscaler +16.5%, Rubrik +15.6%, SailPoint +15.3%, SentinelOne +14.5%, CrowdStrike +13.9% to $235.38, Palo Alto +13.1% to $373.94, Okta +12.0%, Fortinet +9.0%. The index level hid all of it: the S&P 500 closed $760.88, down 0.4%, the Nasdaq-100 $709.18, down 0.8%, the Dow $524.49, down 0.2%, because the two halves of the trade offset. The Magnificent Seven fund closed $70.10, up 0.3%, above its 69.5 weekly line.
    If
    The semiconductor ETF closes below Monday’s $497.40 while the software ETF holds above $105 — the split widening on a second day rather than mean-reverting.
    Why
    A trade that splits on a new fact is telling you which side of the fact it believes. A managed frontier is worth less to the companies whose pricing depends on scarcity and worth more to the companies whose margins depend on compute getting cheaper. One day of that is a reaction; a second day is a repricing.
    Then
    We treat the $505 line as lost and $517.43 — Thursday’s close — as the level the chip index has to recover before the week’s damage is undone. The software side we watch through the print record, not the ETF: Adobe is scored tonight, and a name that is above its paid line on the day the sector had its best day of the year is exactly the case the record exists to test.
  2. Asia, the morning after: Kospi −1.2% to 6,604, SK Hynix −0.9%, Samsung −0.7%; TSMC unchanged at NT$2,380, Taiex −0.7%, MediaTek −2.0%, Alchip −6.4%; Nikkei −0.5% to 63,196, Advantest −4.0%, Tokyo Electron −1.2% — and SoftBank +7.2% after Monday’s −11.3%

    What
    Monday’s Asian session sold the compute layer before New York had opened; this morning it is trading the same idea at a fraction of the size. The Kospi is down 1.2% at 6,604 after Monday’s 3.3% fall, with SK Hynix −0.9% at ₩1,681,000 and Samsung −0.7% at ₩247,250 — the two memory names that fell 6.7% and 4.0% on Monday have not followed the US memory names lower. Taiwan closed with TSMC flat at NT$2,380, MediaTek −2.0%, Hon Hai −0.6%, Quanta −0.2% and Alchip −6.4%, the one name on the island that traded like a US chip. Tokyo, an hour from its close, has the Nikkei −0.5% at 63,196 with the equipment names lower — Advantest −4.0%, Disco −1.3%, Tokyo Electron −1.2%, Screen −0.8% — while Lasertec is +1.7%, Kioxia +0.4% and Socionext +1.1%. SoftBank is the bounce: +7.2% to ¥6,262 after losing 11.3% on Monday, in a session in which the press linked its $10 billion October commitment to OpenAI with the delay of that company’s listing. Hong Kong is −0.6%, the CSI 300 −0.3%, SMIC −0.4%. The Rubin index’s Japanese constituents lost only 0.5% on Monday and the Asia-ex-Japan group 1.2%, against −7.0% for the US names and −7.9% for Europe: the region that sold first on Monday morning sold least by Monday night.
    If
    The Kospi closes above 6,600 and SK Hynix finishes the day down less than 2%, with the Nikkei holding 63,000.
    Why
    Asia’s memory names are the tell for whether the slowdown story is a valuation event or a demand event. If Korea does not follow Micron and SanDisk lower on the second day, the sale in US memory is about US positioning — the calls we wrote about on Monday, the leverage behind them — and not about the order book.
    Then
    We keep the memory-by-geography comparison open: SK Hynix and Samsung against Micron, SanDisk and Western Digital, day by day, and the DRAM ETF against its $58 line, lost during Monday’s session. The Taiwan monthly revenue reports start arriving this week; TSMC’s flat close ahead of them is the number we note.

  4. Rates and oil into the Fed: the 10-year touched 5.00% on Monday, first since October 2023, and is 4.96% this morning; the 30-year 5.33%; Brent $107.34, +1.6% overnight, WTI $103.27; dollar 99.6; gold $4,338; Empire State −8.7 with new orders −19.6

    What
    The other half of Monday was the bond market. The 10-year Treasury yield touched 5.00% during the session — the first print at that level since October 2023 — and closed 4.975%; it is 4.96% this morning, the 30-year 5.33%, and the shape is still a bear flattening, with the front end priced for a hike on Wednesday and the long end refusing to rally on weak data. The Empire State survey printed −8.7 against a forecast near +15 and a prior of 20.6, with new orders at −19.6; the bond market did not buy it, because the same week has Brent at $107.34 — up 1.6% overnight after the Gulf states’ meeting with Iran in Oman was postponed — and WTI at $103.27, and a Fed that meets today and tomorrow with a quarter-point increase priced at roughly four in five. The dollar index is 99.6, up 0.2%; the yen is 154.9; gold is $4,338, down 0.3%, after a 1.5% fall in the gold ETF on Monday; bitcoin is $77,400. Europe closed lower on its chip names — Euro Stoxx 50 −1.0% to 6,260, DAX −0.5%, CAC −0.8%, Stoxx 600 −0.4% — while the FTSE 100 gained 0.4%. Across Treasury ETFs the long bond tracker was flat on the day at $80.93 and the 7-to-10-year fund −0.1%.
    If
    The 10-year closes above 5.00% on the day before the decision — a close, not a touch — with the 2-year still rising.
    Why
    A 5% 10-year is the level at which the AI trade’s capital cost stops being a footnote. Every data-centre lease, every hyperscaler bond, every leveraged fund holding chip calls is priced off it. The Empire State miss shows the growth side is already weakening; the bond market is telling you the Fed will hike into it anyway because of oil.
    Then
    We hold the 5.00% line as the ceiling test for the trade: touched Monday, not closed above. A close above it in Fed week would be the first time this cycle that rates rather than earnings set the tone for the physical layer. The sovereign-pressure board carries the G7 curve and the 10s30s spread; we read it daily this week.

The Midday 10 Mon, Sep 14, 2026 ~60 seconds 12:30 ET

The index is doing very little at midday and the AI trade is doing a great deal. The S&P 500 ETF is at $761.69, down 0.4%; the Nasdaq-100 fund at $709.79, down 0.7%, back above the 704 shelf it opened below and still under Thursday’s $708.69; the Dow fund is flat at $525.46, the Russell 2000 fund down 0.2%, the equal-weight S&P unchanged. Under that surface the weekend’s call to pace the frontier has been priced as a sort, and the sort is the sharpest of the year: the semiconductor ETF is down 5.2% at $499.81, the software ETF up 4.5% at $106.07.

The test we set in this morning’s Pulse — chips below Thursday’s $517.43 with software above Friday’s $101.52 is a premium story, both down together is a market sale — has answered in the first form and then some. The components priced on a race are being sold: Astera Labs −9.9%, Arm −8.9%, SK Hynix’s US line −7.3%, Lam Research −7.2%, Marvell −6.3%, SanDisk −6.3%, Micron −5.6%, Super Micro −5.5%, CoreWeave −5.2%, Intel −5.0%, AMD −4.8% to $491, Broadcom −4.2%, Nvidia −2.9% to $211.96. The users of compute are being bought: Microsoft +1.9%, Alphabet +2.0%, Meta +1.8%, Adobe +4.4%, and the security names that Sunday’s Weekly said were building flow while sold on price are up 12% to 15% in a single session.

The other two prices did not take the morning off. The 10-year yield touched 5.00% for the first time since October 2023 before easing to 4.95%, with a quarter-point hike on Wednesday now priced near 90%; Brent traded to $108.33, above Thursday’s $107.63 settlement, after Oman postponed today’s Gulf–Iran meeting on the Strait, and is $107.06 now; the Empire State survey printed −8.7 with new orders at −19.6. And in the print record, Oracle is below its sold line and Adobe above its paid line with one session to go.

    The board reads like a quiet Monday until the two technology funds. The S&P 500 ETF is at $761.69, down 0.4% and above Thursday’s $757.83; the Nasdaq-100 fund at $709.79, down 0.7%, above the 704 shelf it opened under and below Thursday’s $708.69; the Dow fund flat at $525.46; the Russell 2000 fund down 0.2% at $288.52; the equal-weight S&P unchanged at $215.12. The iShares semiconductor ETF is down 5.2% at $499.81 — through Thursday’s $517.43, through the $505 line we have carried since August, and 6% under its 50-day average at $531.52 — and the VanEck fund is down 4.4% at $543.78; the technology sector fund is down 1.4%. The software ETF is up 4.5% at $106.07, its largest gain of the year, after seven red sessions in eight. The energy fund is down 0.2% at $65.00 with the oil fund up 2.4%: a third day in four on which the sector and the barrel have opposite signs. The 20-year-plus Treasury fund is up 0.4% at $81.22 after the 10-year touched 5%; the 7-to-10-year fund +0.2%. The VIX is 16.86, up 6%. The memory ETF is $55.05, down 6.5% and below the $58 it had held through every test since July. The Magnificent Seven fund is up 0.4% at $70.14, above the 69.5 weekly line.

  2. 2

    UP Security names +12% to +15% on the pacing weekend: Zscaler +14.8%, SentinelOne +14.6%, CrowdStrike +14.7%, Palo Alto +12.1%, Okta +11.3%, Fortinet +7.9%, Cloudflare +6.6% — the thesis of Sunday’s Weekly, paid in one session

    ZSSCRWDPANWOKTAFTNTNETIGV

    Sunday’s Weekly said ten cybersecurity stocks had been sold for a month on clean quarters while every flow reading strengthened, and that frontier models would need a security layer whoever paced them. Monday paid it: Zscaler is up 14.8% at $188.94, SentinelOne 14.6% at $22.63, CrowdStrike 14.7% at $237.09, Palo Alto 12.1% at $370.55, Okta 11.3% at $185.38, Fortinet 7.9% at $168.42, Cloudflare 6.6% at $326.82. The trigger is the same weekend that sold the chips: CrowdStrike’s chief executive answered the pacing essay by saying the industry should make AI progress secure rather than slower, its Fal.Con conference last week shipped products aimed at securing AI agents and their identities, and three brokers raised targets this morning. Third-party evaluators with permanent access inside every frontier lab, which is what the labs committed to, is a procurement statement for the security vendors. We hold the group as the Agentic index’s security sleeve, which sold for three weeks; on Friday it was the index’s weakest sector, on Monday it is the strongest group in the market.

    ALABARMSKHYLRCXMRVLSNDKBEMUSMCICRWVINTCAMDAVGOWDCNVDATSM

    The chip sale has an order and it is not Friday’s order reversed. Friday bought back the names sold hardest into the data; Monday is selling the names priced most on scarcity, and it has widened from memory to equipment in New York in a way it did not in Tokyo. Astera Labs is down 9.9% at $262.44, Arm 8.9% at $241.15, Lam Research 7.2% at $276.85 — the equipment and interconnect names that Asia left alone overnight — alongside SK Hynix’s US line −7.3% at $176.13, Marvell −6.3% at $221.14, SanDisk −6.3% at $1,530, Micron −5.6% at $920.57, Western Digital −4.0%. The compute renters and the power are in it too: CoreWeave −5.2% at $84.33, Super Micro −5.5%, Bloom Energy −6.4% at $257.21. Intel is down 5.0% at $97.80, AMD 4.8% at $491.15 — below $500 — Broadcom 4.2% at $346.78, Nvidia 2.9% at $211.96, TSMC 2.9%. The six names on which Situational Awareness bought calls last week are all down between 4.8% and 7.3% at midday, with the memory ETF, the sixth, down 6.5%. On our three pairs from this morning: chips below Thursday with software above Friday says premium, not volume; the memory ETF below $58 says the floor of the memory economy has broken on the first test; and equipment joining memory in the sale — Lam, Astera, Arm — is the one reading that leans the other way, because equipment is bought a year ahead of the chips it makes. The Rubin index’s factory sectors at the close, against its memory sectors, decide which of the two it was.
