Who owns UNH? UNITEDHEALTH GROUP INC 13F holders and position changes
This reverse-ownership view starts with UNH 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
UNH holder activity in the latest 13F cycle
UNH's reported ownership picture is concentrated in a finite manager sample. 3 active managers reported $136.8M in aggregate value. Tiger Global Management 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. Berkshire Hathaway made the largest measured share-count move at -100.0%. 2 managers 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 is below the trailing average of 4.0. Aggregate value also moves with quarter-end share prices, so dollar changes do not measure active buying by themselves.
UNH becomes easier to judge beside related companies. Related ownership pages include DVA, AAPL, GOOG. Return to UNH stock research for financial statements, earnings, and company risks.
