The period balance: money in, money out
Across the Form 4 filings submitted between Oct 2, 2025 and Oct 2, 2026, Ecolab Inc. open-market activity adds up to 6 purchases worth $3.9M and 13 sales worth $27.1M. The net balance is $23.2M 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 Ecolab Inc.'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 13 sales in the table is flagged as scheduled (10b5-1 plan), the kind signed months ahead and executed automatically. Ecolab's 6 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 Oct 2, 2026, and a Form 4 arrives up to two business days after the trade.
10 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.
