# Why 13F Data Is Always 45 Days Old: The Filing Delay Explained

> Every 13F filing describes positions from at least 45 days ago. Here is why the delay exists and how to use institutional holdings data correctly.

Every 13F filing on 13F Insight describes what an institutional investor held at the end of the previous quarter. By the time you see it, the data is always at least 45 days old.TL;DR13F filings are due 45 calendar days after each quarter ends.Q4 filings (December 31 positions) are due by February 14.Many filers submit on deadline day, so you see December positions in mid-February at earliest.Positions may have changed significantly during the 45-day gap.The Filing CalendarQuarterPositions As OfFiling DeadlineQ1March 31May 15Q2June 30August 14Q3September 30November 14Q4December 31February 14Why the Delay MattersA lot happens in 45 days. If a stock drops 30%, the holder may have already sold. The filing is a frozen snapshot, not a live feed. This is why 13F data works best for understanding long-term positioning from low-turnover filers like Berkshire Hathaway or Dodge & Cox.Amendments Add DelayFilers can submit 13F-HR/A amendments that restate prior holdings. Goldman Sachs filed its Q4 2025 13F as an amendment. These can appear weeks after the original, making data even older.How to CompensateFocus on conviction, not timing: Large positions held across multiple quarters signal genuine conviction.Cross-reference with real-time data: Use earnings calls and stock pages to check if conditions changed.Watch 13D/G filings: Filed within 10 days, much more timely.Track QoQ trends: Changes across 2-3 quarters reveal directional intent.FAQ

## FAQ

### Why are 13F filings delayed 45 days?

The SEC gives managers 45 days to compile holdings data. Large firms with thousands of positions need time to reconcile.

### Can I see 13F data in real time?

No. For more timely signals, use 13D/G filings (10-day deadline) or Form 4 insider reports (2 business days).

### Is 45-day-old data still useful?

Yes for low-turnover investors. Focus on multi-quarter trends rather than treating any single filing as a real-time signal.

### Do all filers wait until the deadline?

Many do, but some submit early. Early filers provide a minor information advantage.
