U.S. Stocks Close on Oct 9: Nasdaq Falls 1.4% as AI Names Under Pressure, Energy Stocks Rally
nashnova research
The Nasdaq fell 1.4% while the equal-weight S&P 500 rose 0.6%, as money rotated out of richly valued tech into energy and consumer staples — Samsung's earnings miss and an OpenAI revenue-accounting dispute hit AI names simultaneously.
Nasdaq down, S&P up — what is the market splitting over?
The Nasdaq dropped roughly 1.4%; the equal-weight S&P 500 gained 0.6% — a rare divergence.
This means → money did not leave equities; it shifted from a handful of expensive tech stocks into other sectors.
In plain terms = the market is not panicking — it is changing seats. Selling what is expensive, buying what is cheap.
Why did AI names sell off together?
Samsung Electronics posted preliminary Q3 results below expectations — operating profit and revenue both missed. Its stock fell 2.4%, the DRAM ETF dropped roughly 5%, and Micron, SK Hynix, and Seagate weakened in sympathy.
The *Financial Times* reported OpenAI's annualized revenue at about $50 billion, roughly $20 billion below the $70 billion figure previously circulating. Nvidia, Microsoft, AMD, Broadcom, Amazon, and Oracle all fell on the headline.
CNBC later clarified: the gap stems from different accounting scopes — OpenAI excluded cloud-partner gross revenue to show a purer own-revenue figure. This means → the actual business may not have shrunk, but the market sold first and asked questions later.
Why did energy and consumer staples buck the trend?
Overnight reports said the Trump administration was considering a strike on Iran before the midterm elections. Crude surged. Trump later denied the report, calling negotiations "productive." Oil pulled back from its intraday high but still closed higher.
Energy was the best-performing sector of the day, directly benefiting from the oil rally.
Coca-Cola and PepsiCo (the latter having just reported earnings) both rose, lifting consumer staples. This reflects capital seeking low-valuation, predictable cash flow as a haven amid uncertainty.
What signal is the bond market sending?
Equity weakness drove money into Treasuries. The yield curve showed bull flattening — yields fell, with the long end leading the decline.
In plain terms = investors are betting the economy may slow, and they are willing to lock in lower long-term rates.
The 30-year Treasury auction came in flat — a prior long-end rally had already compressed the concession. The Treasury then accepted the maximum $6 billion in buybacks across the 20-to-30-year range.
What did Fed officials say?
Governor Waller (voting member): further rate hikes may still be necessary, but they need not come at consecutive meetings — the Fed has flexibility on pace. He flagged overheated AI investment and persistent energy shocks as key drivers of sticky inflation.
St. Louis Fed President Musalem (votes in 2028, hawkish lean): rates should keep rising over the next six to nine months; his contacts are more worried about inflation than about jobs.
This means → both officials lean toward continued hikes; they differ only on speed. Near-term rate-cut expectations are essentially off the table.
What to watch next?
Can the OpenAI revenue-accounting dispute be settled? If the market accepts the "accounting difference" explanation, the AI sell-off may prove a short-term disruption. If doubts spread, valuation pressure persists.
The Fed's eventual rate-hike endpoint — Waller stresses flexibility, Musalem gives a six-to-nine-month window. Where those two timelines cross is the key variable for whether tech valuations can stabilize.
In FX, the dollar weakened as yields fell. The Canadian dollar was the strongest performer, supported by oil. Gold rose while silver fell — even precious metals are diverging.
