Stock Market Today, Oct. 29: Amazon Falls on Q3 Earnings Report and Capex Concerns

Amazon shares fell 4.25% on October 29, 2026, after reporting Q3 earnings that missed Wall Street expectations on both revenue ($201.9B vs. $202.2B expected) and EPS ($1.89 vs. $1.97 expected). The company also provided conservative Q4 guidance of $240-247B versus analyst estimates of $244.51B. However, AWS demonstrated strong momentum with 39% year-over-year growth to $46B, with management projecting growth rates exceeding 40% in 2027-2028, justifying the company's substantial $220B capex investment.
