What is NSP institutional ownership?
This page tracks NSP positions reported by institutional investment managers through SEC Form 13F. INSPERITY INC (NSP) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own NSP?
InsiderSet currently tracks 279 institutional managers reporting NSP 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 NSP shareholders.

When was NSP institutional ownership last updated?
The latest NSP 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.
