Compared with the prior quarter, 3 opened new positions, 20 added to existing stakes, 10 trimmed, 2 exited entirely. 13F holdings are quarter-end snapshots, so these moves reflect positioning as of Q2 2026, not real-time trading.
ERAS is classified in the Health Care sector.
All figures on this page are computed from SEC Form 13F quarterly filings. 13F filers disclose long positions of $100,000 or more within 45 days of quarter end; short positions, options overlays and intra-quarter trades are not included, so treat the numbers as a quarterly snapshot of institutional ownership rather than real-time positioning.
