13F Filings Explained: How to Follow the Smart Money for Free
Four times a year, every institutional investor managing over $100 million must tell the SEC what US stocks it holds. The disclosure is called a form 13F, and it is the closest thing markets have to seeing a great investor's actual homework rather than their interviews.
The most crowded holdings among 105 funds
Counted from the 13F filings themselves. Microsoft is held by more of the funds we track than any other company, which is exactly what makes it a crowded trade rather than a clever one.

What a 13F contains
Every US-listed long position: the security, the share count, and the dollar value at quarter end. Compare two consecutive quarters and you can see what a fund bought, added to, trimmed and exited.
What it leaves out
Honesty matters here, because most coverage skips this part:
- Short positions are not disclosed. A fund can appear long a stock it is net short against.
- Foreign-listed holdings are not included. Only US-listed securities.
- It is up to 45 days stale. A quarter ends 31 March; the filing can arrive 15 May.
- Options rows report notional exposure, which is not the same thing as owning the shares. A serious tracker counts common stock separately.
How to actually use one
Do not copy trades blind: you would be buying with a 45 day lag, without the fund's exit discipline. Use filings the way analysts do: as an idea list filtered by people with skin in the game. When three funds you respect open the same position in the same quarter, that is a research prompt, not an order ticket.
