Large holders · SEC Schedules 13D and 13G
Five percent and over
Anyone who comes to hold more than 5% of a company's voting shares must tell the SEC. A Schedule 13D is filed by a holder who may seek to influence the company; a 13G by one who states it is a passive investor. An amendment updates an earlier filing, and a stake reported as 0% means the holder says it has sold all, or nearly all, of its shares. Every recent 13D and 13G
- BANK OF AMERICA CORP /DE/ 2.4%
- Perceptive Advisors LLC 9.99%
- VIKING GLOBAL INVESTORS LP 9.3%
- Schonfeld Strategic Advisors LLC 5.33%
- BANK OF AMERICA CORP /DE/ 5.9%
