Insider buying report — Thursday, September 24, 2026: 30 open-market buys worth $27.7M
On Thursday, September 24, 2026 the SEC published 30 open-market insider purchases worth $27.7M across 26 companies, against 23 insider sales of $1M or more worth $301.9M. 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.
The largest purchase
Life Insurance Co Nippon (10% owner) at Corebridge Financial, Inc. (CRBG) filed the day's largest purchase: 296,868 shares at $34.31, $10.2M in total, transacted on Sep 22, 2026 and filed Sep 24, 2026.
Behind it: Durable Capital Partners LP at GSHD ($7.1M), Nechmad Yair at NYAX ($4.6M), Marc Grandisson at HHH ($1.6M).

Signals in the day's buying
Of the purchases filed: 4 purchases by a chief executive (ACIC, NYAX, OXM, PWRL); 1 by a CFO (DKS); 8 that belong to an active cluster (AFCG, CSBB, DKS, DY, GAM, GPUS); 15 first-ever purchases by the insider; 21 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 Koch, Inc. at ASPEN AEROGELS INC (ASPN), $58.1M. 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.

Questions this post answers
Which insiders bought stock on Sep 24, 2026?
30 open-market purchases were filed with the SEC on Sep 24, 2026, worth $27.7M across 26 companies. The largest was Life Insurance Co Nippon at Corebridge Financial, Inc. (CRBG), $10.2M. The ten largest are listed above.
Were insiders net buyers or net sellers on Sep 24, 2026?
By dollar value, sellers: $27.7M bought against $301.9M 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 Sep 24, 2026 and was generated early the next morning from the same data the members area uses.
