AI Holders Summary · Q2 2026

Old Republic International Corp, Arthur J. Gallagher's third-largest tracked holder at $43.8 million, carried the identical 190,800-share position this quarter as last — its value rising only on price. That stillness sits next to real, sizable buying elsewhere: Fort Washington Investment Advisors grew its stake 40.4%, a genuine $17.0 million purchase, the largest real buy among the stock's 168 holders. Fenimore Asset Management, the dominant holder at over $132 million, added a smaller real 1.8% ($2.4 million buy). On the sell side, Assenagon Asset Management, flagged quasi-passive, cut 46.0% ($6.6 million real outflow), and Fisher Funds Management cut 12.7% ($6.0 million real outflow) — the two largest genuine sales in the book.

Real conviction elsewhere dwarfs that stillness

Fort Washington Investment Advisors made the clearest real move in the book: shares up 40.4%, from 183,381 to 257,445, a genuine $17.0 million purchase — the largest buy among Gallagher's 168 tracked holders by a wide margin. Fenimore Asset Management, the stock's dominant holder at over $132 million, added a smaller but real 1.8% ($2.4 million buy). Sequoia Financial Advisors added 7.1% ($2.3 million real buy), and Wealth Enhancement Advisory Services added 24.8% ($2.5 million real buy).
