Question 1

What is a 13F filing?

Accepted Answer

A 13F filing is a quarterly report that certain institutional investment managers file with the SEC. It lists many of their U.S.-listed stock, ETF, and option positions as of the end of the quarter.

Question 2

Who has to file a 13F?

Accepted Answer

Institutional investment managers with at least $100 million in qualifying assets under management generally have to file Form 13F. That includes many hedge funds, asset managers, banks, pension funds, and family offices.

Question 3

Why should investors care about 13F filings?

Accepted Answer

13Fs show where sophisticated investors are putting real capital to work. They can help you find stocks being accumulated by high-quality investors, spot new positions, see which holdings are being reduced, and understand portfolio conviction by weight.

Question 4

When are 13F filings released?

Accepted Answer

13F filings are due no later than 45 days after the end of each calendar quarter. That means the data is delayed, but it still gives a valuable view into institutional positioning and changes over time.

Question 5

What does a 13F not show?

Accepted Answer

A 13F usually does not show cash, short positions, many international holdings, private investments, or the exact date a stock was bought or sold. It is a snapshot, not a real-time trade blotter.

Question 6

What is the Insider Edges Alpha Score?

Accepted Answer

Alpha Score is Insider Edges' proprietary ranking system built specifically to evaluate 13F investors and their expected performance. We do not disclose the exact formula, but the score is designed to help users identify higher-quality investors instead of treating every filer the same.

Question 7

How does Insider Edges make 13F data more useful?

Accepted Answer

Insider Edges organizes filings into investor profiles, holdings tables, portfolio weights, activity changes, return estimates, Alpha Scores, and ranking metrics so you can quickly see which investors are worth following and what they are buying or selling.

Question 8

Should I copy every stock a hedge fund buys?

Accepted Answer

No. 13F filings are research inputs, not investment advice. The strongest use case is to generate ideas, compare investor conviction, study position changes, and then do your own research before making decisions.

Question 9

What makes one 13F filer better than another?

Accepted Answer

Quality can depend on long-term performance, consistency, concentration, turnover, holding period, and whether the investor has a repeatable edge. Insider Edges focuses on surfacing higher-quality investors instead of treating every filer equally.
