What is PSIX institutional ownership?
This page tracks PSIX positions reported by institutional investment managers through SEC Form 13F. POWER SOLUTIONS INTERNATIONAL, INC. (PSIX) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own PSIX?
InsiderSet currently tracks 165 institutional managers reporting PSIX 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 PSIX shareholders.
How much PSIX stock do institutions own?

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