The period balance: money in, money out
Across the Form 4 filings submitted between Aug 25, 2025 and Oct 13, 2026, State Street Corporation open-market activity adds up to 1 purchase worth $312k and 20 sales worth $22.7M. The net balance is $22.4M 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 State Street 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.

How to read this data
9 of the 19 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. State Street'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 Oct 13, 2026, and a Form 4 arrives up to two business days after the trade.
13 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.
