First displayed source row from Recent Form 4 activity. The full bounded history and coverage notes remain below.
The displayed observation date is 2026-09-04 and its public availability date is 2026-09-08. Subtracting those calendar dates gives 4 days of disclosure lag. Historical public research can use the record from the availability date, rather than backdating knowledge to the observation date. The calendar-day difference does not assert an intraday publication time.
This row is code S: a sale. A purchase-following rule excludes this sale even if the reported dollar amount is large.
Open the linked original receipts to verify the row, then inspect a second record before drawing a pattern. This public filing observation supplies source evidence, not a completed copy-trading return.

How to read the disclosure dates
The tables report different things: insider transactions, institutional positions and Congressional transaction ranges. Read each table with its source dates and units. They cannot be added into a combined ownership percentage.
Company insiders
SEC Form 4 purchases, sales and awards report transactions and their public filing availability.
Institutional managers
13F reports disclose delayed quarter-end positions. They are not a record of trades between quarters.
Congressional filers
Periodic transaction reports disclose transaction dates and amount brackets. Public filing dates determine what researchers could know.
Read the transaction codes
Awards use transaction code A, purchases P and sales S. An acquisition from an award is not the same as an open-market purchase. Joint filers may share a transaction. Use original receipts and availability dates to interpret the events.
