AI Holders Summary · Q2 2026

Lincoln Capital Corp's NiSource share count fell slightly this quarter — down 0.5%, a real if modest outflow — while the position's reported dollar value actually rose $42,454, entirely on the stock's price gain. Hartford Investment Management shows the identical pattern at a smaller scale. Those are minor contradictions next to the quarter's real headline: Assenagon Asset Management, flagged quasi-passive, cut its stake 25.8% — a genuine $10.6 million outflow, the largest sale among NiSource's 106 tracked holders — while the Pennsylvania Public School Employees' Retirement System, the stock's largest holder, cut 10.0% ($4.0 million real outflow). TEMA ETFs made the largest real purchase, adding 45.3% of its position for a genuine $7.9 million buy, and Union Bancaire Privee added 64.8% ($3.0 million real buy).

The real headline sits at a much larger scale

Those small contradictions are footnotes next to the quarter's genuine sell-side story. Assenagon Asset Management, flagged quasi-passive in this dataset, cut its NiSource stake 25.8% — from 864,692 to 641,329 shares, a real $10.6 million outflow, the largest sale among the stock's 106 tracked holders. The Pennsylvania Public School Employees' Retirement System, NiSource's largest holder, cut 10.0% (846,932 to 761,849 shares, a real $4.0 million outflow). Goelzer Investment Management trimmed a smaller 3.6% ($420 thousand real outflow).
