What is PKOH institutional ownership?
This page tracks PKOH positions reported by institutional investment managers through SEC Form 13F. PARK-OHIO HOLDINGS CORP (PKOH) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own PKOH?
InsiderSet currently tracks 107 institutional managers reporting PKOH 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 PKOH shareholders.
How much PKOH stock do institutions own?

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