What is CBT institutional ownership?

How many institutions own CBT?
InsiderSet currently tracks 372 institutional managers reporting CBT 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 CBT shareholders.
How much CBT stock do institutions own?
Institutional investment managers disclosed approximately $4.82B in CBT holdings for Q2 2026. This figure is reported 13F value as of the filing period, not necessarily today's market value.
When was CBT institutional ownership last updated?
The latest CBT 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.
