# When a trade shows up in the public record

Form 4, Schedule 13D, 13F and congressional reports each run on their own clock. What each contains, how old it is when you see it, and what it never shows.

*https://stockmarketstack.com/guides/when-trades-become-public · background to Insider, 13F & Congressional Trade Trackers*

**Answer:** Every disclosure here arrives late by rule, and the lag is knowable. An insider's Form 4 is due two business days after the trade. A 13D activist stake takes five business days. A fund's 13F lists last quarter's long positions 45 days after the quarter ended. A member of Congress files within 30 days of being notified and no later than 45 days after the trade, and the report may not be published for another 30.

Every tool in this catalogue that tracks insiders, funds or politicians is reading the same public
filings, and every one of them inherits the same lag. The lag is not a vendor's failing and no
subscription fixes it: it is written into the rules that create the filings. Knowing which clock
you are on is the difference between using this data and being surprised by it.

## How it works

Two separate systems, and readers routinely assume there is one.

**Securities disclosures go to the SEC**, onto EDGAR, where they are public within a day of
acceptance and machine-readable immediately. Insider transactions, large stakes, institutional
holdings and fund portfolios all live here.

**Congressional disclosures do not.** Members of the House file with the Clerk of the House;
senators file with the Secretary of the Senate. These are different institutions with different
portals, different formats and a different statute behind them — the
[STOCK Act](https://www.govinfo.gov/content/pkg/PLAW-112publ105/html/PLAW-112publ105.htm), not the
Exchange Act. Nothing a member of Congress files appears on EDGAR.

Within each system the deadline depends on who is reporting and what happened, and the rules below
are the ones a tracker's freshness ultimately rests on.

## The deadlines, form by form

**Form 4 — two business days.** Officers, directors and ten-per-cent holders report changes in
their own holdings before the end of the second business day after execution. That deadline came
from the
[Sarbanes-Oxley Act](https://www.govinfo.gov/content/pkg/PLAW-107publ204/html/PLAW-107publ204.htm),
which rewrote Exchange Act section 16(a) in 2002, and it is a statutory requirement rather than an
SEC scheduling choice.

One exception is worth knowing because it explains filings that look late and are not.
[Rule 16a-3(g)](https://www.ecfr.gov/current/title-17/part-240/section-240.16a-3) lets the clock
start when a broker notifies the insider, for transactions under a pre-arranged plan where the
insider did not pick the execution date — capped at the third business day after the trade. Worst
case, a compliant Form 4 can appear five business days after the event.

**Form 3 — ten days** after becoming an officer, director or ten-per-cent holder. **Form 5 — 45
days after the issuer's fiscal year end**, and this is where transactions that should have been
reported during the year but were not get swept up. A late Form 4 can therefore surface more than a
year after the trade, on a form most trackers treat as an afterthought.

**Schedule 13D — five business days.** Anyone crossing 5% with an intent to influence files within
five business days, and amends within two when something material changes; a 1% change in position
is deemed material. These deadlines are the ones the SEC set in its
[2023 beneficial ownership rules](https://www.govinfo.gov/content/pkg/FR-2023-11-07/html/2023-22678.htm),
which cut the old ten-day window. This is the fastest signal of a position being built rather than
reported.

**Schedule 13G — 45 days after quarter end** for qualified institutions, five business days for
passive investors, with amendments 45 days after each quarter.
[Rule 13d-1](https://www.ecfr.gov/current/title-17/part-240/section-240.13d-1) carries the full
grid. The practical consequence is that the same 5% stake is news in a week if the holder is an
activist and up to four and a half months later if it is an index manager.

**Form 13F — 45 days after quarter end.** Institutional managers exercising discretion over at
least $100 million in
[13F securities](https://www.ecfr.gov/current/title-17/part-240/section-240.13f-1) file a list of
their US-listed long positions. Most file on the last permitted day, and the SEC grants no
extensions.

**Form N-PORT — quarterly, 60 days after fiscal quarter end**, for registered funds. This one is
worth checking rather than remembering: the SEC adopted an amendment moving these reports to
monthly filing, and
[the rule as it currently stands](https://www.ecfr.gov/current/title-17/part-270/section-270.30b1-9)
carries compliance dates in late 2027 and 2028. Anything describing fund holdings as a monthly
disclosure today is ahead of the rule.

**Congressional periodic transaction reports — 30 days, or 45 at the outside.** A covered filer
reports a security transaction over $1,000 within 30 days of being notified of it and in no case
later than 45 days after it happened. The
[House Ethics guidance](https://ethics.house.gov/financial-disclosure/) states the same test as the
earlier of those two dates.

Then a second clock starts. The STOCK Act gives the Clerk and the Senate 30 days after filing to
publish the form. A trade made on day zero, reported on day 45 and published on day 75 has broken
no rule at any point.

## What each form leaves out

**A 13F is not a portfolio.** The SEC's own
[FAQ](https://www.sec.gov/divisions/investment/13ffaq) lists the exclusions: short positions are
not reported, nor is cash, nor are securities that are not on the Official List of 13F securities,
which leaves out most non-US listings. Holdings under both 10,000 shares and $200,000 may be
omitted. It is filed at firm level, so a manager running several strategies appears as one book.

**A Form 4 does not say why.** Since the SEC's
[2022 amendments](https://www.govinfo.gov/content/pkg/FR-2022-12-29/html/2022-27675.htm) the form
carries a mandatory checkbox showing whether the transaction ran under a pre-arranged Rule 10b5-1
plan — the difference between a decision made this week and one made months ago. The box has been
required on reports filed since 1 April 2023, so any series spanning that date changes shape
partway through. Not every tracker exposes it.

**A congressional report gives a range, not an amount.**
[5 U.S.C. 13104](https://www.govinfo.gov/content/pkg/USCODE-2024-title5/html/USCODE-2024-title5-partIV-chap131-subchapI-sec13104.htm)
sets ten statutory bands, the lowest being "not more than $15,000". Since the reporting trigger is
a transaction exceeding $1,000, the most common disclosure in the record spans a fifteenfold range.
Every dollar figure printed by a congressional tracker is a choice it made — midpoint, floor or
ceiling — and the choice is rarely labelled.

**The deadline is weakly enforced.** Under
[5 U.S.C. 13106](https://www.govinfo.gov/content/pkg/USCODE-2024-title5/html/USCODE-2024-title5-partIV-chap131-subchapI-sec13106.htm)
a report filed more than 30 days late carries a $200 fee, which the supervising ethics office may
waive in extraordinary circumstances. That is the ordinary consequence, and it is why filings
months or years late are a recurring feature of the data rather than an anomaly.

## Why third-party trackers exist at all

For SEC filings the answer is normalisation. EDGAR is organised by CIK rather than ticker, a 13F is
whatever the manager typed, and issuer names, share classes and CUSIPs disagree between filings.
Every paid product in this field is selling that reconciliation.

For congressional data the answer is cruder. The Clerk publishes a structured annual index — a
tab-separated file naming each filer, filing type and document ID — but the
[filings themselves](https://disclosures-clerk.house.gov/FinancialDisclosure) are PDFs, and many
are scans of paper with no extractable text. The index tells you a report exists; a human or an OCR
pipeline is what turns it into a row with a ticker in it.

## What you can do about it

**Date every row by the event, not by the filing.** Any tracker worth using exposes both the
transaction date and the report date. If it shows only one, assume it is the filing date and treat
the gap as unknown.

**Match the dataset to the question.** For anything that needs to be current, Form 4 and Schedule
13D are the only two disclosures fast enough to matter, and both are free at source. Building a
thesis on 13F holdings means accepting a picture of last quarter.

**Check the 10b5-1 box before reading anything into a sale.** A planned sale under a pre-existing
arrangement and a discretionary one look identical without it. If the tool you use does not carry
that field, the underlying filing does.

**Never compare a congressional dollar figure between trackers.** They are derived from the same
bands by different rules. Compare the bands, or compare counts of transactions.

**Check a rule before repeating a deadline.** The beneficial ownership windows changed in 2023, the
10b5-1 box arrived in 2023, and the N-PORT move to monthly reporting has a compliance date years
out. Every deadline on this page is linked to the rule or statute that sets it, and those documents
are free to read.

**Go to the source when the answer has to be right.** EDGAR's APIs need no key and publish
submissions within a second of acceptance. The Clerk's index file is a download. A subscription
buys convenience and reconciliation, and it cannot buy you a filing that has not been made yet.

## FAQ

### Which disclosure is the freshest?

Form 4. An officer, director or ten-per-cent holder must report a transaction before the end of the second business day after it was executed, and the SEC publishes it as it arrives. Nothing else in the US disclosure record is that close to the event.

### Why is 13F data described as stale?

Because the rule allows 45 days after the quarter closes and most managers use them. A position opened on the first day of a quarter can be 135 days old before anyone outside the firm sees it, and a position opened and closed inside the quarter never appears at all.

### What happens if a member of Congress files late?

A filing fee of $200, which the supervising ethics office may waive in extraordinary circumstances, and which only applies once a report is more than 30 days past due. Knowing and wilful failures are a separate matter with far larger penalties, but the ordinary late filing costs $200.

### Do congressional reports give the amount of a trade?

No. The statute requires a category rather than a number, and the lowest band covers everything up to $15,000. Any precise dollar figure you see on a tracker is that tracker's own choice of midpoint or floor, not a disclosed amount.

### Does a fund's 13F show everything it owns?

No. It covers long positions in US-listed 13F securities at one instant, filed at firm level. Short positions, cash, bonds, most non-US listings and written options are outside it, and small holdings under both 10,000 shares and $200,000 may be left out entirely.
