InsiderSet ranks institutional holders by their latest reported HLIT position.
What is HLIT institutional ownership?
This page tracks HLIT positions reported by institutional investment managers through SEC Form 13F. HARMONIC INC (HLIT) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own HLIT?
InsiderSet currently tracks 256 institutional managers reporting HLIT 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 HLIT shareholders.
How much HLIT stock do institutions own?
Institutional investment managers disclosed approximately $1.47B in HLIT holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was HLIT institutional ownership last updated?
The latest HLIT 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 HLIT 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 HLIT position after the reporting date.
Are institutions buying or selling HLIT?
Institutional buying and selling can be analyzed by comparing HLIT positions across consecutive 13F reporting periods. InsiderSet's HLIT Ownership Changes page shows institutions that increased, reduced, initiated, or exited positions based on reported 13F holdings. View HLIT ownership changes.
How has HLIT institutional ownership changed over time?
InsiderSet tracks HLIT institutional holdings across multiple 13F reporting periods, allowing investors to compare institutional holder counts, reported value, and reported shares over time.
