Insider trading this week: the 20 biggest buys and 20 biggest sells
Who bought and who sold shares of their own company — by dollar value — in the week of June 29 to July 3, 2026.
Insider trading: how to read this ranking
Methodology. Data pulled from Finviz Elite’s insider register (SEC Form 4 filings for executed transactions and Form 144 for proposed sales). Transactions are filtered on trade dates in the week of June 29 – July 3, 2026 and ranked by dollar value. For buys we include only open-market purchases (“Buy”). For sells we include both executed sales (“Sale”) and proposed sales via Form 144 (badge Form 144), which signal an intent to sell and not always a completed transaction. A useful principle: insider buys usually carry a single meaning (confidence in the stock), while sells can have many causes (tax planning, diversification, scheduled 10b5-1 plans, venture-capital fund distributions after an IPO) and do not by themselves imply a negative view. Data sources: Finviz Elite and SEC EDGAR (Form 4). See all our deep dives on Merlintrader.
Top 20 insider buys of the week
Open-market purchases, ranked by dollar value. The week is dominated by a few strong convictions (Hartree on Hudson Technologies, the Wallbox board after the restructuring, the double buy on Nuvectis) and by several small and micro caps.

Sell · Applied Materials (AMAT) · ~$478.8B
Applied Materials
The world’s largest maker of semiconductor manufacturing equipment. CEO Gary Dickerson appears twice: a proposed sale (Form 144, $70M) and an executed one ($40.8M), typically under a 10b5-1 plan. The stock fell (~-7%) in the chip sell-off.
Next catalyst: Fiscal quarter (mid-August), foundry capex cycle, AI demand and China/export dynamics.
Sell · Alibaba Group (BABA) · ~$230.8B

Next catalyst: Q2 2026 results (early August) and, seasonally relevant, the intensity of the U.S. summer fire season.
Sell · Snowflake (SNOW) · ~$90.2B
Snowflake
Cloud platform for data and AI (data warehouse/lakehouse). Proposed sale (Form 144) by an officer. Continues to sign enterprise partnerships (e.g., data clean rooms for retail media).
Next catalyst: Quarterly results (fiscal, expected late August), consumption growth and AI product adoption.
Sell · Airbnb (ABNB) · ~$89.8B
Airbnb
Global platform for short-term rentals and experiences. Executed sale by co-founder and director Joseph Gebbia. Recent news: a court ruled Airbnb must face a Los Angeles lawsuit over alleged price gouging.
Next catalyst: Q2 2026 results (early August), summer travel season, rollout of the new Experiences/services.
Sell · Micron Technology (MU) · ~$1,100B

Arteris
Semiconductor IP provider (network-on-chip interconnects used in SoCs for automotive, AI and data centers). A proposed sale (Form 144) of 700,000 shares by Bayview Legacy pushed the stock -17%.
Next catalyst: Q2 2026 results, new design wins and royalties from chips in production.
Sell · Credit Acceptance (CACC) · ~$6.9B
Credit Acceptance
Consumer finance company specialized in subprime auto lending through U.S. dealers. Proposed sale (Form 144) by a 10% owner. Just extended a credit facility on better terms.
Next catalyst: Q2 2026 results, delinquency/recovery trends and funding costs.
Bottom line
The buy side this week speaks the language of small caps and founders: refrigerants (Hudson), EV charging (Wallbox), precision biotech (Nuvectis, Faeth), plus regional banks, BDCs and closed-end funds. The sell side is driven instead by large-holder monetizations and scheduled plans from the leadership of AI/semiconductor big caps (Cloudflare, Astera Labs, Applied Materials, Micron, Arista) and by post-IPO fund distributions (Hinge Health, Astera Labs). As always, a single insider does not make a trend: the ranking is there to show where flows concentrate, not to suggest trades.
