13F stock ownership research
COF institutional ownership: holders, changes, and four-quarter trend
This reverse-ownership view starts with COF 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
How institutions moved in COF this quarter
Institutional positioning in COF is visible through the named holders. 3 active managers reported $1.4B in aggregate value. Berkshire Hathaway is the largest tracked holder. The sample is too small for a broad concentration reading.
New, increased, reduced, and exited positions separate the moving pieces. Third Point made the largest measured share-count move at -87.3%. 1 manager initiated positions, led by Soros Fund 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 is above the trailing average of 2.5. 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 MCO, COIN, XYZ. Return to COF 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.
