Cathie Wood’s ARK Invest made multiple portfolio changes last week. The investment firm reduced positions in several U.S. tech stocks while adding to fintech, streaming, and Chinese technology companies.
ARK’s largest sale on October 24 involved Advanced Micro Devices. The ARK Innovation ETF sold 23,717 AMD shares worth $5.57 million. The chip company’s stock has risen in 2025 due to AI chip demand.
Advanced Micro Devices, Inc., AMD
The firm also sold 39,077 Shopify shares valued at $6.53 million. Other sales included 107,510 shares of Iridium Communications for $1.96 million. ARK sold 32,384 Palantir shares and 26,089 Roblox shares, totaling over $9 million.
The ARK Genomic Revolution ETF trimmed its Tempus AI holdings. The fund sold 19,391 shares worth $1.69 million. These sales appear to lock in gains from stocks that performed well this year.
Fintech and Streaming Investments
ARK made its largest purchase in Robinhood Markets. The firm invested roughly $21 million in the trading platform across multiple ETFs. This represents a renewed focus on financial technology companies.
The firm started a new position in Netflix. ARK bought approximately 15,700 shares valued near $17 million. The purchase came after Netflix stock declined recently.
Netflix now holds a position within the ARK Next Generation Internet ETF. The streaming service represents ARK’s bet on digital entertainment platforms.
Chinese Tech Expansion
ARK increased its Baidu holdings across three different ETFs. The funds purchased 51,323 shares totaling $6.18 million. Baidu is expanding its artificial intelligence and autonomous driving operations.
The firm added more than 61,000 Alibaba shares. Wood stated that Chinese tech valuations are about half those of U.S. companies. This makes them more attractive investment targets.
ARK also purchased shares in BYD Company. The electric vehicle maker fits into the firm’s automation and robotics investment theme.
Semiconductor and Biotech Moves
The firm expanded its Qualcomm investment to $33 million. This increases ARK’s exposure to the chipmaker’s operations. Qualcomm produces processors and wireless technology.
ARK’s biotech funds remained active during the week. The ARKG fund bought 10,818 Arcturus Therapeutics shares worth $130,000. This continues steady buying in biotech stocks.
The flagship ARKK ETF added 1.35 million Pacific Biosciences shares for $2.64 million. The purchase shows confidence in sequencing technology. ARK also bought 162,279 shares of 10x Genomics across two funds for $2.17 million.
