See Which Of The Latest 13F Filers Holds AMZN

Between the 09/30/2025 and 12/31/2025 13F reporting periods, aggregate hedge fund holdings of Amazon (AMZN) fell by 75,916,012 shares (from 6,817,123,413 to 6,741,207,401), a decline of about 1.11%. In a recent batch of 31 filings for 12/31/2025, AMZN was held by 25 funds (14 increased positions, 8 decreased, and Attessa Capital LLC fully exited), with the top institutional holders being Vanguard (850,338,457 shares), BlackRock (722,344,070) and State Street (381,681,441). The report notes the limitation of 13F data in not capturing short positions or derivatives exposure, so the net posture of some managers may be obscured.

Analysis

Market structure: The 12/31/2025 13F batch shows a modest aggregate reduction of 75.9M AMZN shares (-1.11%), held mainly by giants (Vanguard 850M, BlackRock 722M, State Street 382M). That size equals roughly ~2 days of average ADV in AMZN, so the flow is material for short-term liquidity but insufficient to change structural ownership dominated by passive managers. Beneficiaries include skilled liquidity providers and options market-makers who can capture widened spreads; active managers with nimble books can harvest short-term dislocations, while short-term momentum traders may be hurt by lower predictability.

Risk assessment: Tail risk includes a regulatory antitrust action or a major AWS outage that could knock 10–25% off market cap in a stress scenario; rising real rates that compress growth multiples pose a 20–30% downside tail for cloud multiples over 12–24 months. Immediate (days) risk is window-dressing/rebalancing; short-term (weeks–months) is earnings / guidance and macro prints; long-term (quarters–years) depends on AWS margin expansion and ad/subscriber monetization. Hidden: 13Fs omit short/derivative hedges—net active exposure may differ materially; catalyst risks include upcoming earnings, FTC actions, or a macro CPI print within 30–60 days.

Trade implications: Direct: consider establishing a 2–3% portfolio long in AMZN (ticker AMZN) via Jan 2028 LEAP calls 10–15% OTM to capture AWS-driven upside, funded by selling near-term call spreads after earnings; size reduce on any >15% rally. Tactical: buy shares on a >5% intraweek pullback (enter within 4 weeks), set initial trim at +15% and hard stop at -10%. Options: sell 6–10 week iron condors or covered calls to monetize elevated skew if implied vol spikes post-13F; allocate 0.5–1% notional to volatility trades.

Contrarian angles: The market is likely over-interpreting the 1.11% reduction—passive holders (Vanguard/BlackRock/State Street) limit freely tradable float so small active flows can exaggerate price moves. Mispricing: options skew may overstate downside; buying deep-term LEAPs while selling short-term premium is underpriced if AWS execution remains steady. Watch for unintended consequences: forced selling by small active funds could create short-term squeezes when passive buyers re-enter—monitor ETF flows and weekly ADV; if weekly net outflows >50M shares, re-evaluate immediately.

Key Decisions for Investors

• Establish a 2–3% portfolio long in AMZN via Jan 2028 LEAP calls (10–15% OTM) to capture multi-year AWS upside; fund by selling 6–10 week call spreads after earnings and trim 30–50% on a +15% move; set a risk stop or hedge if AMZN falls >10% within 6 weeks.
• Tactical entry: buy shares on a >5% intraweek pullback (act within 4 weeks of the pullback) and scale out 30% at +10% and remainder at +15%; position size 1–2% initial exposure if not using LEAPs.
• Volatility trade: sell short-dated (6–10 week) iron condors or covered calls around earnings when IV rises; allocate 0.5–1% notional to capture skew, but avoid exposure during suspected regulatory news windows (next 30–60 days).
