Amazon.com stock is challenging resistance. Why is AMZN stock breaking out?

What Is Driving Amazon’s AWS Growth?A BNP Paribas analyst reiterated a bullish stance and pointed to a path for AWS to become a $1 trillion business over time, leaning on signs of accelerating demand tied to AI workloads. The same note highlighted a second-quarter beat led by AWS and advertising, with worldwide net sales at $201 billion versus a $197 billion consensus estimate.In the quarter, AWS backlog was cited at $496 billion, up more than 150% year over year and 36% quarter over quarter, while operating income was $27.5 billion versus a $23.6 billion estimate and adjusted EBITDA was $53.5 billion versus $50.8 billion. Guidance commentary also flagged a Prime Day timing shift and higher capex, with third-quarter net sales guided to $197 billion to $202 billion and operating income to $22.5 billion to $26.5 billion.Expectations were already elevated into the print, with analysts looking for $1.82 in EPS on about $196.02 billion in second-quarter revenue and guidance calling for $194 billion to $199 billion in revenue, putting even a modest AWS upside surprise in the driver’s seat.Critical Price Levels To Watch For AMZNWith price near $276.97, the stock is pressing the top of its 52-week range ($278.56 high), which often turns into a "prove it" zone where breakouts need follow-through. It’s also extended above its major trend gauges—about 13.9% above the 20-day SMA ($243.86) and about 18.1% above the 200-day SMA ($235.01)—so bulls typically want to see consolidation hold rather than a sharp snapback.MACD is the cleaner momentum lens here: it’s above its signal line and the histogram is positive, which points to improving upside pressure versus the prior downswing. In plain terms, when MACD is above the signal line, it suggests buyers are gaining control even if the stock is still working through overhead supply near highs.
