The period balance: money in, money out
In the Form 4 filings submitted between Sep 3, 2025 and Oct 8, 2026 there is not one open-market purchase of ResMed Inc.: 36 sales worth $28.4M 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 ResMed 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.
Every transaction, code by code
| Code | What it means | Trades | Reported amount |
|---|---|---|---|
| S | Open-market sale | 36 | $28.4M |
| A | Grant or award | 18 | $0 |
| M | Option exercise | 18 | $12.2M |
| F | Tax withholding (shares surrendered for taxes) | 8 | $4.3M |
| Total | Everything filed in the period | 80 | $44.9M |
19 of the 80 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
20 of the 20 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. ResMed 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 Oct 8, 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.
