Cathie Wood’s ARK Invest made a series of large trades on Wednesday, March 4, 2026, as revealed in the firm’s daily fund disclosures.
The biggest move of the day was a sale. ARK offloaded 412,711 shares of Roku across its ARKK, ARKW, and ARKF funds, totaling around $40 million. Roku’s stock had risen 3.7% the day before, and ARK appeared to use that price strength to reduce its position.
Roku, Inc., ROKU
This is not a one-off move. ARK has been cutting its Roku holdings over several trading days, following the company’s fiscal fourth-quarter earnings report on February 14.
On the sell side, ARK also trimmed its position in Taiwan Semiconductor, selling 13,663 shares for roughly $4.9 million. That sale continued a pattern of ARK reducing its TSMC stake in recent sessions.
ARK also sold 202,146 shares of Iridium Communications for about $4.95 million, and dumped over 1.4 million shares of Nextdoor Holdings as part of an ongoing exit from that company.
The largest buy of the day was Amazon. ARK purchased 66,934 shares across five ETFs — ARKK, ARKQ, ARKW, ARKF, and ARKX — for approximately $14.5 million.
Amazon stock rose 3.9% that day after the company announced an additional $21 billion investment in Spain. This came despite reports that Amazon data centers in Dubai were struck by drone attacks linked to Middle East tensions.
ARK also added 176,884 shares of Roblox for around $11.9 million. The gaming platform purchase fits with ARK’s stated focus on innovative technology companies.
Genius Sports was another buy, with ARK picking up 542,828 shares for approximately $3.28 million. The sports data company’s stock had dropped 6.7% that day, and ARK moved to buy into that dip.
ARK rounded out the day with smaller aviation purchases. It bought 200,856 shares of Joby Aviation for nearly $2 million and 419,919 shares of Archer Aviation for about $2.84 million.
Analysts currently hold a “Strong Buy” consensus on Amazon, Roku, TSMC, and Genius Sports. Genius Sports has the highest projected upside over the next 12 months, though it remains a loss-making company.
Amazon and Roku both carry analyst upside projections of more than 30% over the next year.
