Tech Execs Cash Out, Homebuilder Insiders Buy the Dip

Insider activity this month is split clearly between sellers in high-flying tech and buyers in beaten-down housing. The contrast is worth noting.

Arista Networks stands out on the sell side. The networking equipment maker is up 43% year-to-date, and ORTEX data shows insiders have been the heaviest sellers in the US over the past month by value. The stock carries a short score of just 29, meaning short sellers are not yet piling in. But executive disposals at these levels are worth watching ahead of the upcoming Q3 results.

Medline Inc. is the single largest insider sell by value over the past month among large-caps, with over $28 billion in market cap and shares already down nearly 23% this year. Insiders trimming into weakness is a different signal from selling into strength, and the Q3 earnings call on the calendar adds further context.

On the buy side, Lennar Corporation leads US insider purchases over the past month. Lennar has lost 18% in 2026. Insiders opening their wallets at these prices carries more weight than buying into a rally.

Corebridge Financial also shows up as a significant buyer. Its shares are up 17% this year, making the purchase less obvious as a contrarian bet, though the stock still screens with analyst upside of 14%.

Also filing this week, Republic Services and Simon Property Group both show fresh insider buying momentum over the past week. SPG offers a 4.4% forward yield and analysts see limited additional upside.

The week's clearest read: tech insiders are locking in gains; housing insiders are buying what the market has marked down.
