How many institutions own WLKP?
InsiderSet currently tracks 58 institutional managers reporting WLKP 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 WLKP shareholders.

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