What is STLD institutional ownership?
This page tracks STLD positions reported by institutional investment managers through SEC Form 13F. STEEL DYNAMICS INC (STLD) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own STLD?
InsiderSet currently tracks 1,017 institutional managers reporting STLD 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 STLD shareholders.

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