Form 13F—Reports Filed by Institutional Investment Managers

An institutional investment manager that uses the U.S. mail (or other means or instrumentality of interstate commerce) in the course of its business, and exercises investment discretion over $100 million or more in Section 13(f) securities (explained below) must report its holdings on Form 13F with the Securities and Exchange Commission (SEC).

The database of company filings is called EDGAR, and it is searchable.

For example, here is a recent 13F from Berkshire Hathaway.
