Who are the largest institutional holders of STEP?
The largest institutional holders of STEP reported in the latest SEC Form 13F filings include Blackrock, Inc., Millennium Management Llc, Wellington Management Group Llp, Price T Rowe Associates Inc, and Vanguard Portfolio Management Llc. InsiderSet ranks institutional holders by their latest reported STEP position.
What is STEP institutional ownership?
This page tracks STEP positions reported by institutional investment managers through SEC Form 13F. STEPSTONE GROUP INC-CLASS A (STEP) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own STEP?
InsiderSet currently tracks 269 institutional managers reporting STEP 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 STEP shareholders.
How much STEP stock do institutions own?
Institutional investment managers disclosed approximately $3.29B in STEP holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was STEP institutional ownership last updated?
The latest STEP 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.
Are institutional STEP holdings real-time?
No. Form 13F data is not real-time. It represents positions reported by institutional investment managers as of the end of the reporting quarter. An institution may have changed its STEP position after the reporting date.
Are institutions buying or selling STEP?
Institutional buying and selling can be analyzed by comparing STEP positions across consecutive 13F reporting periods. InsiderSet's STEP Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View STEP ownership changes.
How has STEP institutional ownership changed over time?
InsiderSet tracks STEP institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
