Frequently asked
When are 13F filings due?
SEC Rule 13f-1 requires institutional investment managers with $100M+ in qualifying assets to file Form 13F within 45 days after each calendar quarter ends. When the 45th day falls on a weekend or federal holiday, the deadline rolls to the next business day. For Q2 2026 (quarter ending June 30), the deadline is August 14, 2026.
Do funds file right at the deadline?
Most large managers file in the final days before the deadline — the heaviest disclosure wave typically lands on the deadline day itself. A minority file early, which is why new quarters trickle in weeks before the due date.
How current is 13F data when it's published?
A 13F discloses holdings as of quarter end, filed up to 45 days later — so positions can be up to 4.5 months old by the next quarter's filing and may have changed since. It also covers long U.S. equity positions only: no shorts, no bonds, and generally no foreign-listed shares.
