RHUMBLINE ADVISERS

RhumbLine Advisers reported $116.9B in 13F holdings across 4,151 positions as of Q1 2026, maintaining a Technology-heavy posture that now accounts for roughly 35% of the visible book. Nvidia (6.3% of portfolio), Apple (5.6%), and Microsoft (4.1%) remain the three largest single-name line items, anchoring a concentrated tech stance that has been a consistent hallmark of the manager's positioning over recent quarters. The most notable Q/Q move is a new $420M position in RTX Corp, joining Ge Vernova Inc at $413M and Linde PLC at $393M as fresh-initiated stakes — together these three additions signal appetite for aerospace, energy infrastructure, and industrial gases at current levels. On the exit side, RhumbLine liquidated its entire $608M iShares Russell 3000 ETF holding and closed a $426M Salesforce position, trimming exposure to broad-market beta and enterprise software names that had appreciated into Q1. Verizon Communications entered as a $383M new stake alongside AT&T ($353M) and TJX ($344M), reflecting selective confidence in defensive-leaning consumer and telecom names. The aggregate shift — selling ETF wrappers while deploying into single-name industrial and telecom — reads as a move from passive beta to concentrated conviction, consistent with the manager's historical pattern of opportunistically rotating into drawdown-disrupted names.
