The period balance: money in, money out
Across the Form 4 filings submitted between Sep 2, 2025 and Oct 1, 2026, Simon Property Group, Inc. open-market activity adds up to 54 purchases worth $2.4M and 1 sale worth $2.0M. The net balance is $407k 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 Simon Property Group, Inc.'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
Simon Property's 54 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 1, 2026, and a Form 4 arrives up to two business days after the trade.
18 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.
