Cathie Wood’s ARK Invest made a series of targeted portfolio adjustments across its active ETFs during the last week, though the buying and selling activity was contained this week with fewer deals. The trades concentrated in genomics, fintech infrastructure, and selective large-cap technology. ARK Genomic Revolution ETF ( ARKG ) added exposure to the newly listed Alamar Biosciences ( ALMR ), purchasing over 537K shares of the commercial-stage proteomics company , aligning with ARK’s long-term genomics theme. Its shares rose about 33% to open at $22.60 and closed near $23.65. The investment firm parked near $12M in the Fremont, California-based company. The same ARKG fund trimmed positions in Butterfly Network ( BFLY ), selling over 326K shares; 210K shares of CareDx ( CDNA ) sold; and offloaded 67K shares of Twist Bioscience ( TWST ). These moves indicate continued rotation within healthcare toward earlier-stage innovation plays. Another one of the only 2 stocks bought by the manager last week was Netflix ( NFLX ) adding more than 26K shares of the large-cap streaming platform, with an estimated market value of $2.5M in its ARKW ( ARKW ) fund. ARK Next Generation Internet ETF ( ARKW ) reduced exposure to multiple digital infrastructure and fintech-related names. The fund sold 31K shares of Bullish ( BLSH ), 11K shares of Circle Internet ( CRCL ), and 21K shares of CoreWeave ( CRWV ). These reductions suggest some profit-taking in digital asset infrastructure and AI cloud exposure following strong sector performance. ARK also exited positions in healthcare logistics and clinical services company Strata Critical Medical ( SRTA ), with ARK Autonomous Technology & Robotics ETF ( ARKQ ) and ARK Space Exploration ETF ( ARKX ) collectively selling over 182K shares.
