In the Form 4 filings submitted between Sep 22, 2025 and Sep 14, 2026 there is not one open-market purchase of Smurfit Westrock Plc: 3 sales worth $3.4M and zero dollars bought.
Only codes P and S count, where an insider puts in or takes out their own money. A selling balance like Smurfit Westrock Plc's is the norm in the S&P 500, where much of the pay comes as stock. It is not a recommendation to buy or sell: it is what was filed.

How to read this data
None of the 3 sales in the table is flagged as scheduled (10b5-1 plan), the kind signed months ahead and executed automatically. Smurfit Westrock has no open-market purchase (code P) in the history, the most common case in the S&P 500: insiders are already paid in stock. The latest filing is from Sep 14, 2026, and a Form 4 arrives up to two business days after the trade.
20 of the 20 rows in the table carry footnotes from the Form 4 itself, folded into the code column and copied verbatim; a row with no footnote means the filing has none.
