What is GCTS institutional ownership?
This page tracks GCTS positions reported by institutional investment managers through SEC Form 13F. GCT SEMICONDUCTOR HOLDING IN (GCTS) institutional ownership on InsiderSet reflects disclosed 13F holdings among the managers we analyze, not every shareholder of the stock.
How many institutions own GCTS?
InsiderSet currently tracks 58 institutional managers reporting GCTS 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 GCTS shareholders.
How much GCTS stock do institutions own?
Institutional investment managers disclosed approximately $38.55M in GCTS holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was GCTS institutional ownership last updated?
The latest GCTS 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.
