13F stock ownership research
AMZN institutional ownership: holders, changes, and four-quarter trend
This reverse-ownership view starts with AMZN and shows every matching position in SnowballHare's tracked 13F manager universe. It connects holder-level changes with four-quarter history and company research without presenting delayed filings as live ownership.
Deterministic analysis from filing data
The latest institutional read on AMZN
The latest 13F cycle gives AMZN a fresh ownership snapshot. 9 active managers reported $8.1B in aggregate value. Pershing Square is the largest tracked holder. The top five account for 91.5% of tracked value.
New, increased, reduced, and exited positions separate the moving pieces. Berkshire Hathaway made the largest measured share-count move at -100.0%. 1 manager exited, including Berkshire Hathaway. These filings describe quarter-end positions and do not confirm what managers held after the reporting date.
The trailing history shows whether the manager sample is expanding or contracting. Holder count remains near the trailing average of 8.8. Aggregate value also moves with quarter-end share prices, so dollar changes do not measure active buying by themselves.
Peer ownership data gives the holder figures a reference point. Related ownership pages include TSLA, LEN, CMG. Return to AMZN stock research for financial statements, earnings, and company risks.

Manager universe
Holder type breakdown
Holder types are a deterministic classification of SnowballHare's small tracked-manager universe, not an SEC legal category. The breakdown helps distinguish concentrated investment firms from diversified institutions and family-office style portfolios.
Rolling filing history
Last 4 quarters
Quarterly totals aggregate only managers with a tracked filing for the period. A change can reflect buying or selling, stock-price movement, a new manager entering the dataset, or a missing comparable filing.
