Is Amazon Stock Still a Buy After Hitting an All-Time High?

Amazon shares reached an all-time high in November 2025 but were only up about 5% in 2025 overall; the company has delivered strong historical returns (25-year average annual gain ~24%, three-year average ~40%). Current valuation metrics show a forward P/E of 28 versus a five-year average of 44 (implying relative undervaluation) while price-to-sales is 3.6 vs a five-year average of 3; the firm’s growth runway is supported by AWS and a rapidly expanding advertising business as well as network effects and scale. The piece concludes the stock appears reasonably valued and attractive for investors focused on future growth, though it notes differing portfolio recommendations by the Motley Fool Stock Advisor team and discloses the author’s position in Amazon.

Analysis

Market structure: Amazon's cross-segment strength (retail + AWS + advertising) creates asymmetric winners — cloud infrastructure suppliers (NVDA, AMZN) and ad tech partners capture gains while legacy retailers (WMT, TGT) face share pressure. Valuation implies expectations: forward P/E 28 vs five-year 44 and P/S 3.6 vs five-year 3 signal the market is pricing in slower margin expansion; if AWS revenue sustains >20–25% YoY and ad >30% YoY over next 4 quarters, upside re-rating of 30–50% is plausible. Cross-asset: a sustained re-rate would push equity duration higher, compress safe-haven flows into Treasuries (widening 2s10s by 10–25bp) and lift USD vs commodity currencies on higher tech outperformance.

Risk assessment: Tail risks include a major regulatory enforcement action (10–20% probability) that could precipitate a 20–40% drawdown, and an AWS systemic outage or margin squeeze causing a near-term 5–15% hit. Time horizons matter: next 30–90 days driven by earnings and holiday retail data; 6–18 months driven by AWS margin trajectory and ad monetization; multi-year upside hinges on AI infrastructure adoption. Hidden dependencies: a 100–200bp swing in AWS operating margin materially shifts EPS — small margin mix moves dominate valuation vs top-line growth. Key catalysts: quarterly AWS growth >25%, ad revenue acceleration, or a dovish Fed repricing within 3–9 months.

Trade implications: Direct long in AMZN is justified at current prices but should be size-managed (low-to-mid single-digit portfolio exposure) and conditional on AWS/ad cadence; use options to define risk. Relative trades favor long AMZN vs short big-box retailers (WMT/TGT) to isolate cloud/ad exposure. Volatility plays: buy 12–18 month calls or sell 60–90 day put spreads to collect premium if IV is elevated around earnings, and buy short-dated protective puts if regulatory headlines spike.

Contrarian angles: Consensus underestimates ad margin leverage and AWS long-term pricing power — if AWS margin expands 200–300bps over 12–24 months, the stock is materially undervalued. Conversely, the market may be underpricing regulatory risk and consumer cyclicality; a 10–20% policy shock would compress multiples rapidly. Historical parallels: similar to MSFT’s re-rate after cloud margin proof-points — watching margin inflection beats is more informative than absolute revenue beats. Unintended consequence: crowded long positioning into AMZN could amplify drawdowns if rates jump or ad spending reverses, so define entry bands and explicit triggers.

Key Decisions for Investors

• Establish a 2–3% portfolio long position in AMZN (buy shares) over the next 2–6 weeks; add up to an incremental 1–2% if AWS YoY revenue growth >25% and advertising growth >30% in two consecutive quarters; set a tactical stop-loss at 18% below average entry price and a target re-rate of +30–50% over 12–24 months.
• If comfortable acting as buyer at a discount, sell cash-secured AMZN puts 5–10% OTM with 60–90 day expiries to collect premium or acquire stock at a lower basis; size each tranche to no more than 1% of portfolio and limit total put exposure to 3% of portfolio.
• Implement a pair trade: long AMZN 2% vs short WMT 1.5% (equal dollar-weighted) to express cloud/ad outperformance vs brick-and-mortar retail; rebalance after each quarterly earnings and unwind the short if WMT outperforms by >15% relative to AMZN or if AMZN misses two consecutive AWS guidance points.
• Use options for asymmetric risk: buy 12–18 month LEAP calls ~10–15% OTM sized to 0.5–1% of portfolio if conviction is high, or alternatively buy 6–9 month 8–10% OTM puts as portfolio protection if AMZN exposure >3%; prefer buying protection or defined-risk spreads around earnings or regulatory news windows.
