Why super-investors own OLN
Ownership of OLN within this cohort is narrow but meaningful in dollar terms: five managers hold a combined $369M, yet the historical owner count data shows the tracked cohort sat at just one owner for eight consecutive quarters before the current snapshot of five — suggesting several positions were initiated recently and not yet reflected in the trailing series. Christopher Bloomstran carries the highest conviction at 7.2% of his portfolio ($60M), while Yacktman Asset Management and Richard Pzena account for the largest absolute dollar exposures at $122M and $132M respectively. No one in the cohort added, trimmed, started, or exited in 2026Q1, indicating a period of collective stillness after what appears to have been a meaningful influx of interest.
