How many institutions own BCHT?
InsiderSet currently tracks 27 institutional managers reporting BCHT 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 BCHT shareholders.

When was BCHT institutional ownership last updated?
The latest BCHT institutional ownership data on InsiderSet is based on SEC Form 13F filings for the quarter ended June 30, 2026.
