The period balance: money in, money out
Across the Form 4 filings submitted between Nov 7, 2025 and Sep 18, 2026, IDEX Corporation open-market activity adds up to 1 purchase worth $102k and 2 sales worth $3.4M. The net balance is $3.3M 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 IDEX 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.
Every transaction, code by code

| S | Open-market sale | 2 | $3.4M |

16 of the 27 rows carry no usable amount on the Form 4: they count as trades and add $0. The code labels come from the SEC index.

How to read this data
None of the 2 sales in the table is flagged as scheduled (10b5-1 plan), the kind signed months ahead and executed automatically. IDEX's single open-market purchase (code P) is the rare signal: insiders are already paid in stock, so buying more means putting in their own money. The latest filing is from Sep 18, 2026, and a Form 4 arrives up to two business days after the trade.
12 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.
