The period balance: money in, money out
Across the Form 4 filings submitted between Sep 3, 2025 and Sep 17, 2026, Phillips 66 open-market activity adds up to 2 purchases worth $61k and 25 sales worth $63.9M. The net balance is $63.8M on the sell side. Of those 27 open-market trades, 1 arrives with no usable amount —the filing reports no price, or reports one out of scale and the derived amount is voided—: it counts in the trade count and adds zero dollars here.
Only codes P and S count, where an insider puts in or takes out their own money. A selling balance like Phillips 66'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, 22 distinct people or entities have filed Phillips 66 transactions: 1 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.

How to read this data
5 of the 18 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. Phillips 66'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 Sep 17, 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.
