Understanding Form 13F
In this guide, you'll learn what Form 13F is, who files it, what information it contains, and why it's closely followed by investors.
What Is Form 13F?
Form 13F is a quarterly report that certain institutional investment managers must file with the U.S. Securities and Exchange Commission (SEC).
The filing discloses many of the publicly traded securities managed by the institution, providing investors with greater transparency into institutional ownership.
Some well-known firms that file Form 13F include investment managers, hedge funds, banks, insurance companies, and pension funds.
Who Has to File Form 13F?
Institutional investment managers that meet the SEC's reporting requirements must file Form 13F.
These filings are intended to provide the public with information about the investment holdings of large professional money managers.
Individual retail investors are generally not required to file Form 13F.
What Information Does a 13F Include?
A typical Form 13F contains information such as:
- Company name
- Stock ticker
- Number of shares held
- Market value of each holding
- Type of security
- Filing date
Together, this information provides a snapshot of an institution's reported holdings at the end of the reporting period.
When Are 13F Filings Released?
Form 13F is filed four times each year.
Each filing reports holdings as of the end of the previous calendar quarter, meaning there is a delay between when positions are held and when they become publicly available.
Because of this reporting delay, Form 13F should be viewed as a historical snapshot rather than a real-time portfolio.
Why Do Investors Follow 13F Filings?
Many investors review Form 13F filings to:
- Track institutional investment activity
- See what large investment firms own
- Discover new investment ideas
- Compare portfolio changes over time
- Research holdings of well-known fund managers
While these filings can provide valuable insights, they should be used alongside other research rather than as the sole basis for investment decisions.
Where Can You Find Form 13F Filings?
Form 13F filings are publicly available through the SEC's EDGAR database.
You can search by:
- Investment manager name
- Central Index Key (CIK)
- Filing date
Many financial research platforms also organize 13F filings, but the SEC remains the official source for all submitted reports. For help using EDGAR, read our SEC EDGAR database guide.
