13F filings

Every quarter, investment managers with at least $100 million in U.S.-listed stocks and other "13(f) securities" must tell the SEC what they hold, on Form 13F, within 45 days of the quarter's end. Here are the deadlines, what a 13F shows and what it leaves out, and what managers have filed in AI stocks.

The 13F for the quarter ended Sep 30, 2026 is due Monday, November 16, 2026: 45 days after the quarter, moved to the next business day when the 45th day falls on a weekend or a holiday.

What a 13F shows — and what it doesn't

• Who files: institutional investment managers with investment discretion over at least $100 million in 13(f) securities — hedge funds, asset managers, pension funds, banks, insurers, family offices.
• What it lists: long positions at the end of the quarter in 13(f) securities — U.S.-listed stocks and ETFs, listed options, some convertible bonds — with the number of shares and their market value. Since January 2023, values are reported in dollars; before, in thousands.
• What it leaves out: short positions, cash, most bonds, stocks listed only abroad, private companies, and small positions (fewer than 10,000 shares and less than $200,000).
• Timing: a snapshot of the last day of the quarter, made public up to 45 days later. Positions may have changed since.
• Amendments: a manager can refile its whole list (a restatement) or add holdings it left out; the SEC can let a manager keep some positions confidential for a while.
