Insiders Cash Out: AMAT, AGX Lead

A wave of insider selling hit US markets this week. Executives at AMAT and AGX filed notable disposals, while ASTS founder-CEO Abel Avellan dumped $146.7M in shares.

Applied Materials saw its CEO Gary Dickerson file sales totalling over $35M last week. Five executives sold shares in a tight cluster between June 15–18. The board chairman also sold $5.5M. In total, five AMAT insiders unloaded nearly $87M combined.

Argan Inc. told a similar story. Six insiders filed sales worth $79M in total. Chairman William Griffin alone sold 100,000 shares across three trades, pulling in $69M at prices ranging from $643 to $760 per share. CEO David Watson also filed a $6.5M sale. AGX stock has rallied sharply this year, and insiders appear to be locking in gains.

At ASTS, founder and CEO Avellan filed a $146.7M sale on June 23. He sold 2.5 million shares at $58.68 apiece. That's a significant cash-out for the satellite broadband company, which has seen its stock surge in 2025.

NVDA director Mark Stevens also filed two sales totalling $186M on June 23, covering trades made June 18.

Selling dominated across the board this week. No major C-level purchases were filed above $1M. The pattern of cluster selling at AMAT and AGX — where multiple executives filed on the same days — is worth watching closely.
