The period balance: money in, money out
Across the Form 4 filings submitted between Oct 16, 2025 and Aug 17, 2026, Fastenal Company open-market activity adds up to 7 purchases worth $214k and 6 sales worth $5.0M. The net balance is $4.8M 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 Fastenal Company'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
None of the 6 sales in the table is flagged as scheduled (10b5-1 plan), the kind signed months ahead and executed automatically. Fastenal's 7 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 Aug 17, 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.
