Now I have enough information to write the recap.

The Week in Review

It was a bumpy, headline-driven week for U.S. stocks that ended with a split verdict among the major indexes. The Nasdaq Composite ended the week in the green, the S&P 500 eked out a small weekly loss despite rising on Friday, and the Dow Jones Industrial Average lost more than 1.5% for the week. (finance.yahoo.com) Depending on which data provider you check, the exact numbers vary slightly — Trading Economics put the week's Dow loss at 733 points, with the Nasdaq up 2.6% and the S&P 500 up 0.7% (tradingeconomics.com) — but the story was the same everywhere: a hawkish Federal Reserve and surging oil prices tied to Middle East violence pressured stocks early in the week, before a Thursday rebound in semiconductor and AI-related names helped tech pull the Nasdaq back into positive territory. Semiconductors eventually recovered, helping the Nasdaq finish in positive territory, while the Dow suffered its biggest weekly percentage decline since March. (alainguillot.com)

Macro and the Fed

The week's central event was the Federal Reserve's policy meeting. The Fed unanimously raised its benchmark interest rate by 25 basis points — its first rate increase in three years — with Chairman Kevin Warsh explaining that inflation had been too high for too long. (alainguillot.com) That took the federal funds target range to 3.75% to 4.00%. (bondsavvy.com) Just as important as the hike itself was the forward guidance: Fed officials indicated that most policymakers see at least one additional rate increase before the end of 2026, a signal that shifted the conversation on Wall Street considerably. (alainguillot.com)

The move followed a hotter-than-expected inflation report the prior week. The August CPI rose 0.4%, putting the 12-month increase at 3.4%, in line with estimates, but core CPI accelerated 0.3% for the month, a bit higher than expected, with the annual core rate at 2.4%. (cnbc.com) Bond markets reacted sharply to the more hawkish Fed outlook: the 10-year Treasury yield finished the week above 5%, while the two-year yield reached roughly 4.74%, its highest level since July 2024. (alainguillot.com) Separately, an outside review of the Federal Reserve's oversight of Silicon Valley Bank ahead of its 2023 failure found that Fed staff "knew, or should have known" the bank was vulnerable (thestreet.com), adding a bit of reputational noise for the central bank late in the week.

Oil, Commodities, and Geopolitics

Energy markets remained the dominant macro story. Fighting tied to the ongoing Iran conflict escalated, with drone strikes hitting Saudi Arabia's East-West pipeline and renewed attacks on tankers in the Strait of Hormuz. Crude prices rose after Saudi Arabia closed the critical pipeline that bypasses the Strait of Hormuz, following a roughly 9% price surge the prior week as U.S.-Iran fighting escalated. (cnbc.com) Prices spiked further as the crisis appeared to deepen — Libya's national oil company suspended operations at two oilfields amid protests, while Iran-backed Houthi militants carried out renewed strikes on Saudi Arabia. (cnbc.com) By midweek, supply fears eased somewhat: oil prices fell as Saudi Arabia shifted crude exports through the Strait of Hormuz to compensate for the pipeline closure, with Brent settling around $104.82 and WTI near $101.91. (cnbc.com) For the month, U.S. crude had advanced more than 18%. (cnbc.com) By week's end, per one recap, Brent finished the week around $104 a barrel, down about 0.7% for the week.

Notable Movers

  • Chip stocks (Intel, AMD, Arm, Micron, Nvidia): The iShares Semiconductor ETF rose about 3.4% on Thursday, with Intel rising 7.7%, AMD up 6.5%, Arm gaining 8.6%, Nvidia up 2.5%, and Micron climbing 5.5% (finance.yahoo.com), as Intel flagged supply constraints and reports emerged of possible SK Hynix collaboration talks.
  • Cybersecurity names (CrowdStrike, Okta, Palo Alto Networks): Cybersecurity stocks ripped higher amid fresh AI warnings, with CrowdStrike up 14% since Monday, SailPoint up 13%, Palo Alto Networks up 8%, Okta up 10%, and the First Trust Nasdaq Cybersecurity ETF up 5%. (finance.yahoo.com) Palo Alto still slipped Friday after Bernstein cut its rating from Outperform to Market Perform, citing elevated valuations. (thestreet.com)
  • Xenon Pharmaceuticals: Shares tumbled 29% after the company voluntarily paused new patient enrollment in Phase 3 trials of its epilepsy drug candidate azetukalner. (thestreet.com)
  • Nucor: The steelmaker lost 5.33% after issuing third-quarter profit guidance that came in below Wall Street expectations. (thestreet.com)
  • Micron: Shares extended gains into Friday, with Micron reclaiming the $1,000 mark after RBC Capital said its valuation barely reflects AI-driven memory demand. (tradingkey.com)

Week Ahead

The economic calendar is lighter next week, but Fed speakers dominate. The calendar is light on hard data but heavy on Federal Reserve speakers, with central bankers making at least 10 appearances as Wall Street looks for clues on the rate path following September's hike. (kiplinger.com) Friday brings the University of Michigan's final Consumer Sentiment Index for September. (kiplinger.com) On earnings, AutoZone and General Mills report Tuesday morning, while Costco Wholesale reports after the close that day (kucoin.com), alongside a steady stream of smaller-cap reports through the week. Markets will also keep watching oil markets and Middle East developments for any further supply disruptions.
