Walton Trust Dumps $533M, AMAT CEO Sells Big

The biggest insider filing this week came from WMT. The Walton Family Holdings Trust filed Wednesday, disclosing it sold over $532 million in Walmart shares on June 16. The two largest transactions totalled $467M and $65.7M — both at prices just above $121. The Walton family retains a massive stake but the scale of this single-day disposal stands out.

At AMAT, the sell-off was a team effort. Applied Materials CEO Gary Dickerson filed Tuesday disclosing he sold roughly $39M worth of shares across June 15–16 at prices around $590–$597. The board's independent chairman and the company's CTO also filed sales on the same date. Seven insiders in total disclosed transactions, collectively offloading tens of millions. AMAT stock has rallied sharply this year, suggesting executives are locking in gains.

Meanwhile, AAOI saw a coordinated exit. Applied Optoelectronics' founder and CEO, Thompson Lin, filed a $9.8M sale on June 16. An SVP and a director also filed sales in the same window — over $14M combined. Shares had surged strongly prior to the filings, making it a textbook case of insiders cashing out near recent highs.

Not all the news was bearish. Xiaomi filed a $14.4M purchase in 3888 Kingsoft Corporation, reinforcing its strategic relationship with the software firm.
