The period balance: money in, money out
In the Form 4 filings submitted between Aug 26, 2025 and May 12, 2026 there is not one open-market purchase of Masco Corporation: 4 sales worth $11.4M 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 Masco Corporation'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 4 sales in the table is flagged as scheduled (10b5-1 plan), the kind signed months ahead and executed automatically. Masco 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 May 12, 2026, and a Form 4 arrives up to two business days after the trade.
3 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.
