US Market Recap: Nasdaq Falls 2.15% as the AI Trade's Worry Shifts from Valuation to Financing

1. The three indices: Nasdaq 100 down 2.50%, its fifth decline in seven sessions

2. Sectors: six up, five down, a five-point spread between best and worst

3. Big tech: seven of eight fell, Apple the only gainer

4. Semiconductors: an eighth straight decline, the longest since 2008

5. Memory and compute hardware: the denominator is how long the pricing cycle lasts

6. Optical networking: no news of its own, pulled down by two chains at once

7. Neoclouds and software: Friday's epicentre was in the bond price, not the stock price

8. Energy, defence and financials: the only column driven by fundamentals

9. China ADRs: Golden Dragon down 1.30%, more resilient than the Nasdaq

10. Cross-asset: oil back above 100, the curve steepening into an inflation hedge

11. Key events and market logic

• Warsh gives no October guidance at the IMF and the market cuts hike odds from 28% to 17%

  Speaking at the IMF annual meetings in Bangkok, Fed Chair Warsh said the global economy had been more resilient than he expected and that the September meeting had already removed some accommodation, but he declined to signal anything for the October 27 to 28 meeting and said the committee had entered a new communication phase in which it would no longer preview its leanings. CME data showed October hike odds falling from about 28% on Thursday to about 17%, while December odds rose to 74.3% from 50.2% a month earlier.
• A second tanker fire in Hormuz puts the inflation trade back on the table

  Iran's navy said another vessel in breach of rules was found on fire in waters east of the Strait of Hormuz within hours, after a first ship the previous day in the same area. Ukraine struck a refinery in Russia's Ryazan region the same day. Eurasia Group raised its probability of a Persian Gulf escalation from 35% to 65%. November WTI settled at 101.41 dollars, up 3.51%, and December Brent at 109.86 dollars, up 3.72%.
• CoreWeave bonds at 79 cents: a crack opens in AI infrastructure financing

  CoreWeave's five-year CDS touched a record around 1,195 basis points on Thursday, some bonds traded near 79 cents on the dollar in the secondary market, and total debt exceeds 51 billion dollars. Gartner forecasts that 80% of neoclouds will lose independent operating capability by 2030, and Reuters reported that some Anthropic investors cut the expected valuation of a potential listing from 2 trillion dollars to about 1.5 trillion. Jensen Huang said publicly that all of this will pass, and the stock still closed down 11.91%.
• CXMT's DRAM progress rewrites the oligopoly assumption after 2027

  CXMT disclosed progress on a 4F² DRAM architecture. Nothing changed in current-quarter supply and demand; what changed is how the market discounts the length of the memory upcycle. The three largest memory makers this week: Micron down 13%, Samsung Electronics down 17.8%, SK Hynix down 24.3%. Same-day performance in China and Korea diverged sharply, with the KOSPI up 2.05%, which says the selling was concentrated in US-listed memory and AI hardware.
• Treasury par curve: front end lower, long end flat, 2s10s two basis points wider

  The official par curve on October 16: 2-year 4.74% (-3bp), 3-year 4.82% (-3bp), 5-year 4.89% (-2bp), 10-year 5.09% (-1bp) and 30-year 5.43% (flat), with 2s10s steepening from 33bp to 35bp. In the same week September CPI at 3.7% year on year and PPI at 6.3% both beat expectations, and the front end still fell, which says the market treats a hike as a tool against inflation rather than a confirmation of overheating.
• Earnings and flows: Alcoa beat, and TIC data show foreign holdings rebounding after two declines

  Alcoa beat on third-quarter profit and rose 2.55%, up more than 9% at one point intraday; Truist earned 1.16 dollars a share adjusted against expectations and rose 1.07%; Travelers gained 1.47%, while M&T Bank fell 1.54% and Citizens 0.11%. The Treasury's TIC report showed foreign holdings of US Treasuries up 83.3 billion dollars in August to 9.3317 trillion, the first rebound after two monthly declines; Japan cut for a fourth month and UK holdings crossed 1 trillion dollars for the first time.

12. What the session says

• The nature of the selloff changed from expensive valuations to difficult financing, and the evidence is in the bonds, not the stocks
  CoreWeave's 11.91% decline is the result; bonds at 79 cents and CDS at 1,195bp are the cause. Those two prices are set by different holders, since equity buys growth and credit buys repayment. If credit spreads stop widening next week while the stock keeps falling, that is sentiment clearing out; if spreads keep widening, it is the prelude to a credit event. The window to watch is capex guidance from Meta, Tesla, Texas Instruments and IBM after the close on October 21, and order commentary from GE Aerospace, RTX, Northrop and General Motors before the open on October 20.
• Oil and technology stocks are now two ends of the same chain
  With WTI back above 100, the direct effect is higher costs for airlines, chemicals and transport, and the indirect effect is a rebound in inflation expectations that pins long-end rates high, and long-end rates are the denominator in technology valuations. This oil move is priced on Hormuz transit risk, with Eurasia Group lifting its escalation probability from 35% to 65%, not on demand. Crude will not fall because the economy weakens, so technology gets no valuation tailwind. Conversely, once transit through the strait normalises and oil and the long end fall together, that is the fastest path to the end of this AI hardware clearing.
• Bonds and equities are telling two stories, and neither is wrong
  Equities are trading higher AI financing costs while the bond market is buying the front end: 2-year -3bp, 10-year -1bp and 30-year flat. The common misreading is to call that a recession signal, but September CPI at 3.7% and PPI at 6.3% are nowhere near a recession. The real reason the front end fell is that hike odds went from 28% to 17%: the bond market believes the Fed does nothing in October, and the equity market does not believe AI can fund itself. Both can be true at once, and the price is a compressed equity risk premium.
• The defensive trade is crowded, and the next leg is priced by earnings
  Consumer staples, utilities and energy all led, Coca-Cola set a record and utilities gained 1.40%, so defensive crowding is close to a high for the year. On the other side, the KBW bank index is still on its longest weekly losing streak since 2008, and Friday's 0.49% gain in financials does not change the monthly trend. The real dividing line runs through October 20 and 21: if hyperscaler capex guidance holds, the oversold bounce after five straight declines in the Nasdaq 100 comes quickly; if it is cut, the eighth decline in the Philadelphia index is only the beginning and defensive outperformance runs another quarter.
