Amazon Is Underperforming the S&P 500 and Nasdaq-100. Could Oct. 29 Mark a Turning Point?

Amazon shares are up slightly over 7% in 2026, trailing the S&P 500's 11% gain and Nasdaq-100's 16%; over five years, Amazon returned roughly 49% versus the S&P 500's 80% total return. Ahead of its Q3 report after the Oct. 29 close, the article cites strong AWS, e-commerce and digital-ad growth but notes lower margins and substantial investment: Amazon raised its annual capex target from about $200 billion to $220 billion last quarter. The author views the spending, including investment in Trainium and Graviton AI chips, as a long-term growth investment rather than treating one report as a near-term stock catalyst.

Analysis

The key issue is conversion, not whether AI demand is real: Amazon must turn incremental AWS capacity into sustained utilization, pricing power, and cash generation before rising depreciation and operating costs dilute returns. A capex increase without corresponding evidence of contracted demand or improving AWS economics would widen the gap between investment and monetization—and could keep the multiple constrained even if headline revenue beats. Conversely, stronger advertising contribution can improve the consolidated mix, but it is not yet proof that retail economics have structurally changed.

Over the next several sessions, the Oct. 29 report is an event risk, not a reliable standalone turning point. Over 1–3 months, watch AWS growth and forward commentary against the capex trajectory, plus free-cash-flow direction; those determine whether investors treat spending as capacity for profitable growth or as a continuing cash-flow drag. Over 6–18 months, the second-order risk is that the cloud capex race benefits infrastructure suppliers while leaving hyperscalers with underutilized assets and higher depreciation. Microsoft and Alphabet are relevant competitive benchmarks, but the article provides no comparable valuation or returns data to support a clean relative-value conclusion. The contrarian angle: weak relative share performance alone does not establish mispricing; the market may be discounting a longer payback period than the bull case assumes.

Key Decisions for Investors

• Avoid initiating a full-size directional position immediately ahead of earnings. Consider a staged AMZN long only after the report if AWS demand commentary supports the spending plan and free-cash-flow guidance does not deteriorate; this gives up some gap-up upside in exchange for less exposure to a capex-driven selloff.
• For a relative-value expression, consider a small AMZN-underweight versus MSFT or GOOG into the event, then reassess after results. The rationale is lower near-term sensitivity to Amazon’s retail-heavy mix and investment burden—not a claim that either peer is cheap. Keep sizing modest because no valuation or consensus data are supplied.
• Treat higher capex without clearer AWS monetization or a worsening cash-flow outlook as a thesis-falsification signal; reduce exposure if post-report price action breaks below the pre-report range. Revisit the long case if subsequent updates show AWS demand converting into cash generation rather than only additional buildout.
• Verify AWS growth, capex guidance, free-cash-flow trajectory, and management’s explanation of capacity utilization before acting. Without those details, the report supports a watch-and-confirm approach rather than a high-conviction earnings trade.
