Amazon shares closed at $266.03 on November 4 after surging 6.12% on elevated volume, driven by reassessment of AWS momentum following the October 29 Q3 release. AWS revenue accelerated to 39% year-over-year growth, reaching a $184 billion annualized run rate with a $578 billion backlog, while company-wide operating margins hit a record 13.9%. Heavy AI-related capital expenditures of approximately $220 billion for 2026 pressured free cash flow but are viewed as positioning the segment for sustained 40%+ expansion in 2027–2028. Q4 guidance of 12–16% revenue growth aligns with seasonal expectations ahead of the holiday period. Trader sentiment reflects these fundamentals alongside broader market dynamics, with the November 5 close sensitive to intraday momentum and any macroeconomic data releases.
