Who Bought A Large Number Of Shares?
Schedule 13D (or the abbreviated version, schedule 13G) would be the most likely place to find this info. When a person or group of persons acquires beneficial ownership of more than 5% of a voting class of a company’s equity securities registered under Section 12 of the Securities Exchange Act of 1934, they are required to file a Schedule 13D with the SEC.  Schedule 13D reports the acquisition and other information within ten days after the purchase. Any material changes in the facts contained in the schedule require a prompt amendment.  You can find the Schedules 13D for most publicly traded companies in the SEC’s EDGAR database.  A 1% change in the amount of ownership is considered material.
