What is KEX institutional ownership?
This page tracks KEX positions reported by institutional investment managers through SEC Form 13F. KIRBY CORP (KEX) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own KEX?
InsiderSet currently tracks 468 institutional managers reporting KEX 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 KEX shareholders.
How much KEX stock do institutions own?
Institutional investment managers disclosed approximately $7.18B in KEX holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was KEX institutional ownership last updated?
The latest KEX institutional ownership data on InsiderSet is based on SEC Form 13F filings for the quarter ended June 30, 2026. Form 13F filings are generally reported after the quarter ends, so the holdings shown represent the latest publicly disclosed positions rather than real-time institutional holdings.
