GM
General Motors CO
8 super-investors hold GM worth a combined $1.92B. The largest position: Harry Burn at 2.6% of their portfolio. No cohort buying or selling was filed on the name this quarter. Cohort Conviction Score: 36 — ranked #195 of 724 scored stocks.
Why super-investors own GM
Conviction here is concentrated rather than broad: eight super-investors hold GM, but the $1.9B in combined exposure is dominated by Bill Nygren's $1.0B position and Viking Global Investors' $684M stake, together accounting for nearly 90% of cohort ownership. Maximum portfolio concentration is modest at 2.6%, held by Harry Burn; Samantha McLemore, Francis Chou, and Prem Watsa round out the holder list at 1.4–2.1%. Activity in 2026Q1 was entirely static — no additions, trims, new entrants, or exits across the cohort. The longer-term ownership trend shows a slow build from two holders to three over the past two years, now plateaued for five consecutive quarters, suggesting interest has stabilized rather than compounding further.
