What funds disclosed, months after the fact.
Funds named in investing reels, read from their real SEC filings: what they held on the last day of a quarter, what changed since the quarter before, and how old that picture is by the time anyone can see it.
Situational Awareness LP's latest 13F, to scale: the positions describe Jun 30, 2026; the fund may have traded every day since.
What a 13F cannot tell you
- A 13F is filed up to 45 days after the quarter ends and lists positions as of the last day of that quarter. The fund may have traded since.
- It lists long positions in US-listed securities and listed options only: short positions, most derivatives, cash and non-US holdings are missing, so it is not the whole portfolio and not its hedges.
- It gives no trade dates or prices. A change between two filings is the net of everything done in the quarter.
- Option rows (PUT/CALL) show the underlying value, not the option premium.
- Following a 13F is not a clone of the fund: Boostio shows it as delayed research leads, never as trade instructions.

Fund claims we could not tie to a filing
13F filings, answered
What is a 13F filing?
A quarterly report that U.S. institutional investment managers with at least 100 million dollars in certain U.S.-listed securities file with the SEC. It lists their long positions in those securities on the last day of the quarter and is due within 45 days after the quarter ends.
Can I copy a fund with it?
Not really. The positions are up to 45 days old when filed and older when you read them, short positions and most hedges are not disclosed, and no trade dates or prices are given. Boostio shows 13F changes as research leads to check against current evidence, never as instructions.
Why these funds?
Each was named in an investing reel Boostio reviewed. Before anything is shown, the fund's CIK and name are verified against SEC EDGAR on every refresh; a name that does not match is not shown as verified.
How are tickers matched?
A 13F lists issuers by name and CUSIP, not ticker. Boostio matches a name to a ticker only when it is a unique match in the SEC company ticker list; otherwise the CUSIP is shown instead of guessing.
Research, not advice. Boostio shows dated public data with its source and labels its own hypotheses as such. Paper only: nothing here is a real trade, and no result here is a promise.
