Institutional owners (13F) 42 filers · $69.2M total · As of June 30, 2026
Institutions that report holding this stock in their quarterly SEC Form 13F. Long positions only; a single filer may appear twice for separate option legs. Large offsetting put/call legs typically reflect market-making or hedged inventory, not directional conviction.
Institutional activity — Q2 2026 vs prior quarter
| New positions | Exited positions | Increased | Decreased | Net shares change |
|---|---|---|---|---|
| 13 | 9 | 7 | 6 | — |
Compared to Q1 2026. SEC Form 13F filings are due within 45 days of quarter-end plus a short buffer for late filers — quarters still inside that window are skipped in favor of the most recent fully-reported pair. Change vs prior quarter not shown: filer coverage differs too much between these two quarters for a reliable comparison.
