How many institutions own CABO?
InsiderSet currently tracks 144 institutional managers reporting CABO holdings in the latest available 13F data. This count reflects institutions included in the SEC Form 13F filings analyzed by InsiderSet and should not be interpreted as the total number of CABO shareholders.

The latest CABO institutional ownership data on InsiderSet is based on SEC Form 13F filings for the quarter ended June 30, 2026.
