The Week in One Paragraph

Wall Street logged a split-decision week that favored old-economy stocks over tech. The S&P 500 closed the week at 7,659.44, down 1.95% on the week, and the Nasdaq Composite fell 4.48%, marking both indexes' worst week since June. The Dow, meanwhile, rose 0.67% to 52,002.41 (portfolio-terminal.com), registering a second straight weekly gain (finance.yahoo.com). The Nasdaq's four-week winning streak was snapped (finance.yahoo.com), with the damage concentrated in chips and AI-infrastructure names: semiconductor stocks as measured by the PHLX Semiconductor Index lost 11.41% for the week (portfolio-terminal.com). The culprit was a combination of a hotter-than-expected inflation report and spreading anxiety over how AI companies are financing their massive data-center buildouts, which triggered a rotation out of growth stocks and into defensive, value-oriented sectors.

Macro and the Fed

Wednesday's inflation report set a cautious tone for the week. The consumer price index showed annual inflation of 3.7% in September after rising 0.6% for the month, while core CPI posted an annual reading of 2.6% after climbing 0.3% (cnbc.com). Energy prices were a major factor again as gasoline rose 9.1% and accounted for half the increase in the index (cnbc.com), tied to continued tensions between the U.S. and Iran in a war launched in late February (cnbc.com). Producer prices confirmed the hot trend, with PPI final demand jumping 1.3% month-over-month to reach a 6.3% year-over-year rate, the highest since 2022 (favillephoto.com). On the Fed, policymakers had already signaled via their September dot plot a median rate of 4.1% by year-end, implying one more quarter-point rate rise (admiralmarkets.com), and economist Mark Zandi said the hot CPI print "gives more support to the argument that the Fed is going to continue raising rates." (cnbc.com) The Fed is now in its official blackout period that runs from Saturday, October 17 through the next FOMC meeting (kiplinger.com), so no policy speakers are scheduled before the late-October decision.

Oil, Commodities, and Geopolitics

Energy was the week's standout sector as the Israel–Iran conflict kept pressuring the Strait of Hormuz. A surge in attacks in the waterway caused oil transit to fall again after crude flows had recovered to pre-war levels in September, with nearly 20.8 million barrels a day passing through the strait as recently as October 8 versus a pre-war average of 17.1 million (aljazeera.com). Brent crude climbed steadily through the week, and by Friday escalating attacks in the Strait of Hormuz pushed Brent crude toward $110 per barrel (alainguillot.com), while WTI crude for November delivery rose about 10.41% on the week to settle near $101.41 (portfolio-terminal.com). That backdrop helped energy stocks and reinforced inflation worries that were already showing up in the CPI data.

Notable Movers

  • CoreWeave (CRWV): The AI-cloud provider's stock became the week's flashpoint. Its shares nosedived 15.5% on Wednesday, while yields on its debt jumped, with its 9.625% bond due 2032 trading near a 14.8% yield to maturity (cnbc.com), fueling broader worries about debt-funded AI expansion.
  • Oracle (ORCL): Caught in the CoreWeave contagion, Oracle dropped nearly 9% and lost about $38 billion in market value as CoreWeave's bond scare spread (247wallst.com).
  • Micron Technology (MU): Fell early in the week as shares dropped 3.9% on Monday amid investors assessing increasing competition from China's CXMT, which reported progress on a new chip structure (cnbc.com).
  • Goldman Sachs (GS): A bright spot in bank earnings — net revenues reached $18.68 billion, up 23% from a year earlier, with net earnings up 29% to $5.29 billion, far outpacing a consensus EPS estimate of $13.09 (heygotrade.com), driven by a surge in equities trading.
  • JPMorgan (JPM): By contrast, JPMorgan earned $15.3 billion, up 6% but below the $16.3 billion analyst forecast, with fixed-income trading revenue declining 4% (beinsure.com).
  • Defensive consumer names: As money rotated out of tech, Coca-Cola rose 6.64%, Walmart climbed 6.70% and Procter & Gamble gained 5.37% (portfolio-terminal.com) for the week.

Week Ahead

The coming week (October 19–23) brings a lighter economic calendar but a heavier earnings slate. Several major companies are scheduled to report, including Meta, Tesla, Netflix, 3M, GM, Philip Morris, Texas Instruments, IBM, P&G, Honeywell, American Express and GE Aerospace (tradingeconomics.com), with Meta and Tesla reporting Wednesday, October 21, after the close (heygotrade.com). On the data front, Friday brings S&P Global's flash Services and Manufacturing PMIs along with the University of Michigan Consumer Sentiment Index (kctrades777.substack.com), while Thursday features initial jobless claims, the Conference Board's Leading Economic Index, and the Kansas City Fed Manufacturing Survey (kctrades777.substack.com). Fed officials remain in their blackout period ahead of the next FOMC meeting on October 28 (tradingeconomics.com), so there are no major policy speeches scheduled. Investors will likely keep watching oil prices and AI-financing headlines for further market direction.
