Amazon (AMZN) stock dropped 4.43% to $222.55 on November 18, 2025, under intense pressure following a sector downgrade and growing worries about the negative impact of AI's economics on the company's future profitability[1][3]. The decline leaves shares down 13.5% from their all-time high, highlighting investor anxiety over both industry-wide and company-specific risks[1]. No new major company announcements were reported overnight, and pre-market trading shows a modest rebound to $223.95 (+0.63%), suggesting the market is digesting the previous session's sharp decline. Broader market sentiment remains cautious amid global equity weakness, but Amazon's move was notably larger than the overall market.
