Exec Sales Dominate the Filing Queue

The most striking insider pattern in the latest available filings covers the period through early September 2026, with several high-profile chief executives disclosing large open-market sales.

Fast Retailing's founder and CEO Tadashi Yanai filed in late August that he sold 3.18 million shares in 9983 for $1.57 billion, one of the largest single executive disposals in the dataset. The trade took place on 18 August and was reported three days later.

AMD CEO Lisa Su filed on 18 August that she sold roughly 156,000 shares for $80.2 million, with the trade executed on 14 August. Amphenol CEO Richard Norwitt filed a $80.8 million sale of 500,000 shares on 3 August.

Arista Networks CEO Jayshree Ullal filed on 7 August that she sold $74.4 million worth of shares. Palantir CEO Alex Karp filed on 24 August disclosing a $53.6 million sale executed four days earlier. Chevron CEO Mike Wirth filed an $61.5 million sale in mid-August.

On the buying side, Evolution AB major shareholder Kenneth Dart filed a $569 million purchase of EVO shares, though this reflects a large-stake holder rather than a C-suite executive buy.

One name to note on social media radar is TSLA, which is generating significant chatter around its proposed all-stock merger with SpaceX, with analysts warning the 24% premium could turn negative.
