How many institutions own POWL?
InsiderSet currently tracks 542 institutional managers reporting POWL 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 POWL shareholders.
How much POWL stock do institutions own?

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