C-Suite Exodus at Argan, Buying Blitz at Fiserv

Two contrasting insider patterns emerged this week. At AGX, a wave of selling hit as six insiders filed disposals totalling over $42M. The CEO, Chairman, CFO, and three directors all filed sales between June 16–18. Chairman William Griffin sold 50,000 shares for $32.2M at $643 apiece. CEO David Watson followed, filing a $6.5M sale. The stock has been a strong performer, and insiders appear to be locking in gains near all-time highs.

The opposite signal came from FISV. Five Fiserv executives filed purchases this week. The CAO and CFO each bought roughly $500K worth of shares around $49–50. Two directors added positions alongside them. The cluster of buying across C-suite and board members signals internal confidence. Fiserv shares have pulled back sharply from recent highs, making the coordinated buying notable.

XRAY also saw a director buying cluster. Six board members filed purchases at $9.85–$10.15 per share, just as the dental equipment maker trades near multi-year lows.

Meanwhile, the Walton Family Holdings Trust filed sales of $533M in WMT shares this week — the largest disclosed insider transaction by value in the past seven days.
