The period balance: money in, money out
Across the Form 4 filings submitted between Sep 3, 2025 and Oct 15, 2026, Microsoft Corporation open-market activity adds up to 2 purchases worth $3.4M and 16 sales worth $195.6M. The net balance is $192.1M 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 Microsoft 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.

Who has traded
Over the 15 months of history, 13 distinct people or entities have filed Microsoft Corporation transactions: 2 bought on the open market and 7 sold. Counted by CIK, the fixed number the SEC gives each filer, and not by name, which each filer types their own way.
Of the 7 who sold on the open market (16 sales in all), the three biggest sellers account for $165.1M of the $195.6M: 84% of the money in three people.

How to read this data
4 of the 16 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. Microsoft's 2 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 15, 2026, and a Form 4 arrives up to two business days after the trade.
15 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.
