IBKR
Interactive Brokers Gro-cl A
6 super-investors hold IBKR worth a combined $1.44B. The largest position: Bryan Lawrence at 30.5% of their portfolio. No cohort buying or selling was filed on the name this quarter. Cohort Conviction Score: 75 — ranked #3 of 724 scored stocks.
Why super-investors own IBKR
Ownership within this cohort is narrow but deeply held: six managers carry a combined $1.4B in IBKR, with Bryan Lawrence running it at a striking 30.5% of his portfolio — the highest concentration here by a wide margin — followed by Robert Vinall at 13.4%. The bulk of aggregate dollar exposure comes from larger funds: William Von Mueffling holds $754M and John Armitage $421M, though both at modest portfolio weights. Activity this quarter was nonexistent — no additions, trims, or exits — and the cohort count has held at a steady four core owners for eight consecutive quarters before two more joined. Interest is stable rather than building, reflecting long-term conviction rather than fresh momentum.
