Trading volume spiked 20% above its 30-day average, suggesting heightened selling pressure at higher levels.

Amazon Web Services continues to drive the company’s top-line momentum, delivering $33 billion in revenue during Q3—a 20% year-over-year increase. Operating margin in the cloud segment expanded to 30.5%, up from 28.7% a year earlier, as efficiency gains in data center utilization and AI-related service offerings offset rising infrastructure costs. AWS backlog grew 18% sequentially, highlighting strong enterprise demand for machine-learning and storage products.
