Week: November 2–6, 2026 | Updated November 8, 2026
Weekly Market Pulse
U.S. equities fell despite Friday’s recovery: S&P 500 −2.7%, Nasdaq Composite −3.4% and Russell 2000 −2.1% for the week. The November 5 AI-sector rout, the worst S&P 500 session since April 2025, dominated trading. October payrolls rose by 165,000 and unemployment stood at 4.1%, keeping interest-rate sensitivity high. AP · BLS.

AI repricing dominates despite Friday’s rebound
On November 6, the S&P 500 closed at 7,376.86 (+0.3% Friday), Nasdaq Composite at 24,579.42 (+1.1%) and Dow at 51,285.73 (−0.5%). The respective weekly changes were −2.7%, −3.4% and −0.9%; Russell 2000 lost about 2.1%.
The damage came on Thursday, November 5: the S&P 500 fell 4.4% to 7,353.73 and the Nasdaq Composite 5.5% to 24,315.00, leaving the Nasdaq 11.9% below its October 6 record. AP tied the selloff to fears of tougher AI regulation and slower data-center construction after the November 3 midterm elections gave Democrats control of Congress, on top of stretched AI valuations; Nvidia fell 9.3% and AMD 17.3% that day. AP, November 5.
Friday’s rebound was partial: the semiconductor ETF SMH gained 3.6% after an 11.2% drop on Thursday and still lost 11.2% on the week. Market breadth still needs confirmation rather than inferring a fresh uptrend from one session.
AI and technology under pressure
Nasdaq Composite lost 3.4% on the week; XLK fell 8.23% and SMH 11.20%. Investors remain sensitive to AI data-center spending, paybacks and the new political backdrop for AI regulation.
Payrolls stronger than expected
October payrolls +165,000, unemployment 4.1%, average hourly earnings +0.4% on the month and +3.1% on the year; August and September were revised up by a combined 84,000. Fed target range 3.75–4.00% after October 28. November 10 CPI is the next key test. BLS.
XBI slips; event risk remains
XBI −2.42% and IBB −1.83% from October 30 to November 6, with a 6.7% XBI drop on November 5. Individual FDA catalysts and dilution risks cannot be inferred from the ETF alone.
Constructive confirmation to watch
Broader participation, technology stabilization and small-cap resilience over multiple sessions; a single bounce is not confirmation.
Risks to watch
November 10 CPI, November 13 PPI, the 10-year and 30-year Treasury auctions, AI valuations and regulation, guidance resets and separate biotech financing risk.

Sessions in review: November 2-6
Each daily return uses the preceding session in the same price series. Daily changes compound to the weekly change; adding rounded percentages will not reproduce it exactly. Wednesday’s broad rally (Dow +3.0%) did not extend to semiconductors (SMH −2.75%); Thursday left all five ETFs negative for the week.

Interpretation: a hike is back in the debate
The Fed held its range at 3.75–4.00% on October 28 with two dissents in favor of a 0.25-point increase. Firm payrolls and wage growth keep that debate open, but neither the jobs report nor one CPI print decides the December 8-9 meeting. Federal Reserve statement

Sources and methodology
The November 2–6 ETF market map and session table use official regular-session closing prices, comparing each session with the previous one and November 6 with October 30. Price changes exclude distributions, are not total returns and are not live quotes. Index closes are from AP; Treasury yields are daily par yields published by the U.S. Treasury.
Primary economic and company releases are linked in each section. Sector breadth is the count of positive returns among eleven sector ETFs, not stock-level breadth. Interpretations are editorial and do not attribute moves to a single cause or to an unconfirmed consensus surprise.
