First displayed source row from Recent SEC transactions. The full bounded history and coverage notes remain below.
The displayed observation date is 2026-09-14 and its public availability date is 2026-09-15. Subtracting those calendar dates gives 1 day 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.

Source evidence and strategy eligibility
The transactions below come from filings; a historical tracker separately simulates following eligible events. Joint filers can report the same transaction, and an owner can have filings at multiple companies. Public availability, amendment lineage and verified coverage determine which events a historical tracker may use.
The current directory marks this owner's filing coverage verified.
