On Friday, February 27, Cathie Wood’s ARK Invest executed multiple strategic portfolio adjustments. The trading activity encompassed fresh acquisitions alongside continued position trimming in technology, defense, and biotechnology sectors.
Kratos Defense & Security Solutions received the day’s most substantial capital deployment. ARK acquired 252,169 shares valued at $23.2 million. The company specializes in unmanned aerial vehicles and autonomous defense technology, aligning well with ARK’s investment philosophy centered on robotics and automation.
The second-largest acquisition targeted CoreWeave, a provider of AI-focused cloud infrastructure. ARK accumulated 198,980 shares totaling approximately $19.4 million, distributed between its ARKK and ARKW exchange-traded funds.
CoreWeave, Inc. Class A Common Stock, CRWV
ARK’s CoreWeave purchase coincided with a dramatic 19% decline in the stock price. The selloff was triggered by fourth-quarter financial results that revealed robust revenue growth but simultaneously disclosed expanding losses and elevated capital expenditures that concerned market participants.
By purchasing shares during the downturn, ARK signals confidence that the market’s negative response reflects temporary sentiment rather than fundamental business deterioration. CoreWeave operates in the AI computing infrastructure space, which continues experiencing substantial demand expansion.
CoreWeave maintains a Moderate Buy rating consensus among Wall Street analysts. With eleven Buy recommendations and eight Hold ratings, the average analyst price target sits at $114.18, suggesting potential upside of approximately 43.5% from current trading levels.
ARK Continues Exiting Teradyne and Rocket Lab Positions
Regarding disposals, ARK liquidated 38,773 Teradyne shares valued at $12.9 million across several ETFs. The company manufactures semiconductor testing equipment and industrial automation systems. This sale continues a consistent pattern of position reduction ARK has maintained with Teradyne throughout recent trading sessions.
ARK simultaneously divested 46,921 shares of Rocket Lab valued at approximately $3.4 million. The aerospace company had recently announced quarterly financial results exceeding both earnings and revenue analyst projections, yet shares nevertheless declined roughly 5% during Friday’s trading session.
Rocket Lab’s quarterly report highlighted robust launch operations and an expanding order pipeline. Nevertheless, the inaugural flight of its larger Neutron rocket system was delayed until late 2026, potentially contributing to investor disappointment.
Additional Trading Activity in Biotechnology and Technology Sectors
ARK liquidated 46,389 shares of Roku valued at $4.3 million from its ARKK fund. The firm provided no public commentary regarding the rationale for this divestment.
Within biotechnology holdings, ARK established a position of 459,525 shares in Generate Biomedicines worth $7.4 million through its ARKG fund. Concurrently, it disposed of 39,423 Ionis Pharmaceuticals shares for $3.2 million.
ARK exited 10,590 Deere & Co shares valued at $6.6 million and reduced its Guardant Health position by 27,334 shares worth $2.7 million.
Smaller portfolio adjustments included offloading 205,211 PagerDuty shares for $1.5 million and acquiring 14,097 Brera Holdings shares valued at approximately $15,600.
The combined CoreWeave and Kratos acquisitions represented ARK’s two most significant individual transactions on February 27, accounting for more than $42 million in total capital deployment.
