13F stock ownership research
AMD institutional ownership: holders, changes, and four-quarter trend
This reverse-ownership view starts with AMD 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 AMD
The latest 13F cycle gives AMD a fresh ownership snapshot. 3 active managers reported $604.0M in aggregate value. ARK Invest is the largest tracked holder. The sample is too small for a broad concentration reading.
Position changes show where the quarter differed from the prior filing. Soros Fund Management made the largest measured share-count move at +101.4%. 1 manager exited, including Coatue Management. 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 2.8. Aggregate value also moves with quarter-end share prices, so dollar changes do not measure active buying by themselves.
The final cross-check is to compare AMD with similar company pages. Related ownership pages include NVDA, PLTR, MSFT. Return to AMD stock research for financial statements, earnings, and company risks.

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.
