Why super-investors own ACIW

Ownership of ACIW within this cohort is narrow and has been stable for at least eight consecutive quarters, with just two managers holding a combined $17M. Wallace Weitz is the meaningful conviction holder, carrying ACIW at 1.1% of his portfolio — roughly $15M — while Joel Greenblatt's $2M position represents a rounding error in his book. Neither manager added, trimmed, nor exited in 2026Q1, and cohort count has held at one or two for the full eight-quarter lookback. Interest is neither rising nor fading; this is a quiet, long-held position concentrated almost entirely in one manager's portfolio.
