What is QNST institutional ownership?
This page tracks QNST positions reported by institutional investment managers through SEC Form 13F. QUINSTREET INC (QNST) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own QNST?
InsiderSet currently tracks 219 institutional managers reporting QNST 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 QNST shareholders.
How much QNST stock do institutions own?

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