Insiders Buy as Sellers Hit Tech

Insider trading data from the vendor table, current to September 8, 2026, shows limited open-market activity for US names this week. The EDGAR Form 4 tables used for first-party SEC filings were unavailable in this environment, so the freshest US discretionary trades cannot be confirmed. The findings below draw on the most recent available data.

The largest disclosed transaction from the latest filing date came from JPMorgan Chase, which filed an acquisition of 431 million shares in 293 Cathay Pacific Airways worth roughly $737 million, consistent with a passive 5%-owner position change rather than a directional bet.

In South Korea, the CEO of A108490 ROBOTIS filed a $75 million sale on September 8. That is a substantial discretionary disposal by a founder-level executive and warrants attention.

On the buy side, an investment company lifted its stake in Indonesian lender SUPA PT Super Bank Indonesia by $1.7 million, the most notable open-market purchase in the dataset.

Across S&P 500 names screened via ORTEX, LEN Lennar led the index for insider buying volume over the past month, notable given the homebuilder's stock is down 18% year-to-date. ORCL Oracle and SPG Simon Property Group also registered meaningful buying. On the sell side, CRWD CrowdStrike and AVGO Broadcom executives were the heaviest sellers, though plan-driven disposals are common at both firms.

Full US Form 4 data from SEC EDGAR would sharpen this picture considerably.
