Cathie Wood's ARK Invest released its daily trading disclosures for Tuesday, October 6, 2026, detailing a session in which the asset manager sold shares of Teradyne while adding to several other positions across its exchange-traded funds. ARK publishes these daily trade summaries for its family of thematic exchange-traded funds, providing a running record of how the firm's funds are repositioned from session to session. The day's most prominent buying was concentrated in two electric air taxi companies, Archer Aviation and Joby Aviation, whose combined purchase totaled roughly $16.2 million.
ARK Trims Teradyne While Buying Veracyte
ARK sold 61,547 shares of Teradyne, a supplier of semiconductor test equipment, through its ARK Autonomous Technology & Robotics ETF (ARKQ) and ARK Space Exploration & Innovation ETF (ARKX). The sale totaled about $27.4 million and continues a pattern of the firm reducing its Teradyne position in recent sessions.
On the buying side, ARK picked up 389,509 shares of Veracyte, Inc. (VCYT), a molecular diagnostics company, through its ARK Genomic Revolution ETF (ARKG). That purchase was worth about $18.6 million and follows several days of ARK adding to the stock.
The firm also sold 54,873 shares of SpaceX-related holdings through its ARK Next Generation Internet ETF (ARKW), worth about $9.4 million. That sale came shortly after ARK had been buying shares of the same company.
Air Taxi Purchases Lead the Day's Activity
The largest story from the day's trading involved two electric air taxi companies, both developers of electric vertical takeoff and landing (eVTOL) aircraft. ARK bought 2,566,731 shares of Archer Aviation and 753,330 shares of Joby Aviation across its funds. Combined, the two purchases were valued at about $16.2 million.
Both air taxi stocks have had a rough year. Archer Aviation has fallen about 38 percent since January, while Joby Aviation has dropped about 56 percent over the same period, even as ARK added to both names on Tuesday. For both companies, certification is the key gate between today's test programs and the start of commercial passenger service, which is why progress with regulators remains the sector's central near-term focus.
Archer Aviation Expands Its Plans
Archer continues to work toward certifying its Midnight aircraft, its eVTOL designed for short urban flights, while building out other parts of its business. The company is developing defense-related projects through a separate division called Archer Defense.
Archer has also announced plans to acquire Wisk Aero, Insitu, and SkyGrid, three companies with ties to Boeing. The proposed deals would add autonomous flight technology and military drone capability to Archer's operations. Progress on Midnight certification and on the proposed acquisitions will be among the company's next key updates to watch.
Spending on aircraft development, certification, and manufacturing has raised concerns among investors about the company's future capital needs. Analyst sentiment remains largely positive, however. Five of the six analysts covering Archer rate the stock a buy, giving it a Strong Buy consensus rating, and the average price target implies about 149 percent upside from current levels.
Joby Aviation Moves Toward Certification
Joby is in the final stage of FAA type certification for its aircraft and has logged thousands of test flights as part of that process. The company expanded its business this year by acquiring the passenger operations of Blade Air Mobility, and it is preparing to launch flights in Dubai as part of its international expansion plans. Certification milestones and the Dubai launch are the company's most immediate developments to watch.
Joby recently faced a legal setback when a federal jury ordered it to pay $116.9 million. The jury found that Joby had misappropriated trade secrets and broken a confidentiality agreement involving Aerosonic. The verdict adds a new financial obligation for the company as it works through certification and prepares for international expansion.
Wall Street coverage of Joby is more divided. Among the seven analysts covering the company, two recommend buying the stock, three rate it a hold, and two recommend selling, producing an overall Hold consensus. The average price target implies about 99 percent upside from current levels.
