The period balance: money in, money out
Across the Form 4 filings submitted between Sep 11, 2025 and Oct 8, 2026, MGM Resorts International open-market activity adds up to 3 purchases worth $77.1M and 4 sales worth $12.3M. The net balance is $64.8M on the buy side.
Only codes P and S count, where an insider puts in or takes out their own money. A buying balance like MGM Resorts International's is the less common case in the S&P 500: its insiders are already paid in stock and still put in their own money. 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. MGM Resorts International'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 Oct 8, 2026, and a Form 4 arrives up to two business days after the trade.
6 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.
