The cluster is dominated by passive rebalancers, not informed active capital — the signal is weak. Monitor for an active-fund 13D/A filing or material catalyst before attributing conviction to this flow.
Executive Summary
Three passive mega-managers (Morgan Stanley, Invesco, BofA) accumulated $15.4M in INBX during Q3 2025, led by Morgan Stanley's 15x position increase to $14.9M. A single passive seller (UBS) trimmed ~80% of its holdings, reducing by $339K. The cluster is net-conviction positive but entirely passive, suggesting index/rebalancing flows rather than fundamental conviction.
