What are 13F Filings?

13F filings are submitted quarterly by any manager controlling investments of at least $100 million.

These managers can be private trusts, banks, insurance companies, investment advisors, and hedge funds. Funds must submit their list of qualifying 13F securities no more than 45 days after the end of quarter date.

13F Filings for the September 30th, 2021 Quarter are due November 15th, 2021.

6,073 filings already imported!

What can private investors learn from these filings?

Plenty. Individual investors can take advantage of the research already done by hedge funds by using the data disclosed in 13F filings. Hedge Funds have access to levels of investing talent and capital far beyond most individual investors or small RIAs.

But is the data of any value after 45 days?

Research has found that "Yes" despite the time lag, 13F holdings data is still valuable when released. The key is to focus on funds that tend to hold securities long-term and have a higher concentration of high conviction picks. Funds who favor short-term trading or whose portfolio is so diversified that it basically follows the S&P 500 will generally make poor candidates for copying.

How do I know which funds are the best to copy?

Free Email Alerts

Receive email alerts whenever funds or stocks you are interested
in submit new filings to the SEC.

For certain filings like 13F, 13D/G, 8-K, Form D, and insider forms 3,4 and 5, the WhaleWisdom email alert will contain
specific details about the actual contents of the filing giving you useful data
without having to actually read the filing yourself.

The email alert service is absolutely free,

only requiring that you sign-up for a free account.

What are 13D/G Filings

Whereas 13F filings give you a snapshot of a fund's holdings 45 days after quarter end, 13D/G filings are typically filed within 10 days of an investor acquiring at least 5% of a single publicly traded company. The information contained in the filing is more current than 13F filings.

13D/G filings are often released before the closing bell. Using WhaleWisdom's email alert system, you can be notified
when these filings are released in real-time and receive actionable info you can use of a Whale's buy or sale
of a security you've been targeting.

WhaleWisdom will often tweet 13D/G events in real-time for some of the more popular funds.

See daily 13D/G activity or Search for past 13D/G transactions.
