Insider buying report — Thursday, October 1, 2026: 64 open-market buys worth $31.6M
On Thursday, October 1, 2026 the SEC published 64 open-market insider purchases worth $31.6M across 43 companies, against 20 insider sales of $1M or more worth $159.5M. By dollar value the selling outweighed the buying, which is the usual state of affairs — executives at large companies sell on schedule, and buy only on purpose.

Life Insurance Co Nippon (10% owner) at Corebridge Financial, Inc. (CRBG) filed the day's largest purchase: 216,818 shares at $33.67, $7.3M in total, transacted on Sep 29, 2026 and filed Oct 1, 2026.

Signals in the day's buying
Of the purchases filed: 8 purchases by a chief executive (CINT, CRESY, FLNA, GTLB, PRHI, RDGL); 5 by a CFO (CTM, HELP, PRHI, SKYH, XENE); 27 that belong to an active cluster (CTM, DKS, FUL, GME, GPUS, LILA); 24 first-ever purchases by the insider; 33 bought at least 25% below the recent high. These are the flags the members area scores on — a CFO buying with their own money has historically been the strongest single-insider signal, and a cluster of three or more buyers the strongest of all. The cluster guide explains the scoring.

The largest sale was Genworth Holdings, Inc. at Enact Holdings, Inc. (ACT), $37.1M. Sales are shown from $1M upward only; below that they are overwhelmingly scheduled 10b5-1 plans and tax-driven, and listing them would bury the signal.
Context: the market-wide picture
For the week starting Sep 21, 2026, 33% of open-market insider filings across the whole market were buys (227 buys against 457 sales). The long-run average sits near a third, because insiders buy for one reason and sell for many. The full weekly series since 2019 is on the insider sentiment index.
Questions this post answers
Which insiders bought stock on Oct 1, 2026?
64 open-market purchases were filed with the SEC on Oct 1, 2026, worth $31.6M across 43 companies. The largest was Life Insurance Co Nippon at Corebridge Financial, Inc. (CRBG), $7.3M. The ten largest are listed above.
Were insiders net buyers or net sellers on Oct 1, 2026?
By dollar value, sellers: $31.6M bought against $159.5M in sales of $1M or more. Selling normally dominates because executives sell on pre-set schedules; what matters is the buying, which is voluntary.
What counts as an insider buy here?
Only Form 4 transactions with code P — an open-market purchase paid for with the insider's own money. Grants (A), option exercises (M) and shares withheld for tax (F) are excluded, because they follow vesting schedules set years earlier and say nothing about what the insider thinks of the price.
How current is this?
The SEC publishes Form 4 filings through about 10 pm Eastern each business day. This report covers everything published on Oct 1, 2026 and was generated early the next morning from the same data the members area uses.
