As of Q2 2026, 19 SEC-registered investment managers reported holding ZLAB (ZAI LAB LTD) in their latest 13F filings, with a combined reported value of $207.59M across 10.93M shares. That is +53.6% by share count (+3.81M shares) versus the previous quarter, while reported value moved +61.8%. Ownership is concentrated: the five largest holders account for 85.9% of reported value and the top ten for 98.1%.

Compared with the prior quarter, 2 opened new positions, 7 added to existing stakes, 8 trimmed, 4 exited entirely. 13F holdings are quarter-end snapshots, so these moves reflect positioning as of Q2 2026, not real-time trading.

ZLAB 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.
