ZG institutional ownership: holders, changes, and four-quarter trend
This reverse-ownership view starts with ZG 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 ZG
ZG's current holder list starts with reported scale. 2 active managers reported $56.0M in aggregate value. Tiger Global Management 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. Tiger Global Management made the largest measured share-count move at 0.0%. 1 manager initiated positions, led by 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 is above the trailing average of 1.8. 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 AAPL, AXP, KO. Return to ZG 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.
