The period balance: money in, money out
Across the Form 4 filings submitted between Nov 25, 2025 and Aug 31, 2026, Allegion plc open-market activity adds up to 3 purchases worth $591k and 8 sales worth $2.6M. The net balance is $2.0M on the sell side.
Only codes P and S count, where an insider puts in or takes out their own money. A selling balance like Allegion 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
2 of the 8 sales in the table are flagged as scheduled (10b5-1 plan): signed months ahead and executed automatically, so they say nothing about what the insider thinks today. Allegion's 3 open-market purchases (code P) are the rare signal: insiders are already paid in stock, so buying more means putting in their own money. The latest filing is from Aug 31, 2026, and a Form 4 arrives up to two business days after the trade.
17 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.
