Insiders Cash Out $120M+ Across Tech and Power

Four executives at AMAT filed sales totalling over $79M this week. CEO Gary Dickerson led the wave. He sold more than $41M worth of shares across multiple transactions on June 15–16. Chairman Thomas Iannotti added another $5.5M. CTO Om Nalamasu filed $9.7M in sales on the same days. Applied Materials stock has climbed sharply this year, and insiders appear to be locking in gains near the $590–$600 range.

DELL saw two insiders file $73.8M in combined sales, reported on June 17. Dell's stock has rallied hard in 2026 on AI server demand. The timing of these filings — clustered in a single week — stands out.

Power plant contractor AGX showed one of the most striking patterns. Four insiders filed sales totalling over $41M. CEO David Watson sold nearly $6.5M on June 15. Chairman William Griffin Jr filed a $32M sale the same week. Two independent directors also sold. The coordinated exit at a stock price above $640 is notable for a mid-cap company.

The Walton Family Holdings Trust filed twin WMT disposals worth a combined $532M, reported June 18. While family trust sales at Walmart are routine, the scale keeps them among the week's biggest disclosures.

No significant US insider purchases above $1M were filed this week. The one-sided flow — all sells, no buys — is a signal worth watching.
