Amazon Soars as AWS Growth Accelerates. Is It Too Late to Buy the Stock?

Amazon's shares surged following robust Q3 results, primarily driven by Amazon Web Services (AWS) which saw a 20% year-over-year revenue increase to $33 billion and 10% operating income growth, exceeding consensus estimates due to strong AI infrastructure demand. The company highlighted significant AI advancements, including fully subscribed Trainium 2 chips and Project Rainier's expansion, leading to an increased capital expenditure guidance to $125 billion for AI data centers. Overall revenue climbed 13% to $180.2 billion, with EPS up 36% to $1.95, both surpassing analyst expectations, while advertising revenue also grew 24%, underscoring accelerating AWS growth and strong operating leverage across its e-commerce and high-margin advertising segments.

Analysis

Amazon's Q3 results significantly surpassed expectations, primarily driven by its Amazon Web Services (AWS) segment, which posted its strongest revenue growth since 2022. AWS revenue surged 20% year-over-year to $33 billion, exceeding the $32.4 billion consensus, while operating income rose 10% to $11.4 billion, largely due to strong demand for AI infrastructure and successful deployment of custom Trainium 2 AI chips.

Beyond AWS, Amazon demonstrated broad operational strength, with North America sales climbing 11% to $106.3 billion and international sales up 14%. Advertising revenue also outperformed, increasing 24% to $17.7 billion, surpassing the $17.3 billion analyst consensus. The company has increased its capital expenditure guidance from $118 billion to $125 billion, signaling continued heavy investment in AI data centers and robotics.

Overall, Amazon's total revenue grew 13% year-over-year to $180.2 billion, exceeding the $177.8 billion consensus, and EPS jumped 36% to $1.95, well above the $1.57 expectation. Q4 guidance projects revenue between $206 billion and $213 billion, representing 10-13% growth, with operating income forecast at $21 billion to $26 billion, indicating sustained positive momentum.

Despite robust operational performance and accelerating growth, the stock's year-to-date gain of less than 15% suggests a potential disconnect with underlying business strength. The stock trades at a forward P/E of approximately 33x 2026 analyst estimates, which, given the accelerating growth and strong operating leverage across segments, implies solid upside potential.

Key Decisions for Investors

• Investors should assess Amazon's accelerating AWS growth and substantial AI infrastructure investments as key drivers for future performance, considering the stock's relatively subdued year-to-date appreciation.
• Monitor the successful execution of increased capital expenditures and the rollout of new AI technologies like Trainium 3, as these are critical for sustaining competitive advantage and capturing market share.
• Evaluate the stock's current valuation of 33x 2026 forward P/E in the context of its improving operating leverage and robust revenue growth across its cloud, e-commerce, and high-margin advertising segments.
