Why Did AMZN Stock Go Up or Down Today?

Amazon (AMZN) is a three-business company: e-commerce, AWS cloud infrastructure, and digital advertising. Its stock is increasingly driven by AWS margin expansion and ad revenue growth rather than retail sales alone.

What causes AMZN to move?

• AWS growth: Cloud segment revenue growth is the primary AMZN catalyst - acceleration drives outsized gains; deceleration triggers selloffs.
• Advertising revenue: Amazon's ad business has grown into a high-margin powerhouse that analysts track closely each quarter.
• E-commerce margins: Fulfillment cost efficiency and operating leverage in the retail segment are key margin drivers.
• Consumer spending: Macro data on consumer health (retail sales, credit card spending) directly impacts retail revenue expectations.
• Regulatory pressure: FTC antitrust actions and EU regulatory fines are ongoing headline risks for Amazon.
