Insider Buying Report · SEC Form 4 · October 2026

October 2026: insiders bought $1.13B, and sold about 6 times that

Company insiders reported $1.13B of open-market purchases filed in October 2026, across 220 companies and 280 insiders. Most of the dollars came from large outside holders rather than executives. And the look-back: 20 of 82 insider buys from July 2026 beat the S&P 500 over the next 90 days.

Insider selling was larger: $6.33B across 4,881 sale transactions. Most insider selling is routine, often scheduled in advance under Rule 10b5-1, so the sales total says less than the buys.

Same-day buys by many directors often follow a board-wide or scheduled purchase, which usually says less than an executive buying on their own.

How we counted

  • Open-market purchases (Form 4 code P) of $10K or more, filed with the SEC from Oct 1, 2026 to Oct 31, 2026, for the companies InsiderPrint tracks. Months go by filing date; some filings report older trades.
  • Trades whose price or share units could not be verified against the market price are left out of every total (the same checks as the rest of the site).
  • Roles come from the filer's title: CEO and CFO, other officers, directors, and 10% owners (often funds or other companies).
  • Not investment advice. Insider purchases are one input, and most don't beat the market.
