Noticed an interesting portfolio move over the weekend. Kathy Wood and her team at ARK Invest conducted a serious review of their positions on February 27th — buying on dips, selling overvalued assets. All of this looks like a classic move by an experienced investor.

The biggest purchase was Kratos Defense & Security Solutions — about $23 million. The company specializes in unmanned systems and autonomous defense solutions, which logically aligns with Kathy Wood’s investment thesis on robotics and automation. The second major move was buying CoreWeave for $19.4 million. Cloud infrastructure for AI, with shares falling 19% after quarterly results. The results were mixed — strong revenue, but losses and expenses exceeded expectations. A typical situation where the market overreacts, and fundamental players buy at the bottom.

CoreWeave operates in the AI computing segment, where demand is growing aggressively. On Wall Street, consensus remains positive — an average target price of around $114, offering a potential upside of 43% from current levels. Kathy Wood clearly believes in the long term.

But there were also sales. ARK sold off 38,000 shares of Teradyne for $12.9 million — a manufacturer of equipment for testing semiconductors. This continues the trend of reducing the position in the company. Also sold part of Rocket Lab for about $3.4 million, even though the company just reported results above expectations. Rocket Lab showed strong launch activity and a growing order backlog, but the launch of the new Neutron rocket was pushed to the end of 2026. It seems this cooled investors, and Kathy Wood decided not to hold.

In small moves: sold $4.3 million worth of Roku from ARKK, bought biotech Generate Biomedicines for $7.4 million through ARKG, reduced the position in Ionis Pharmaceuticals. Also divested some Deere and Guardant Health.

Overall, the picture is clear — Kathy Wood and her funds are shifting focus to high-potential segments like AI infrastructure and defense technology, while reducing positions in companies where the potential is already priced in. The two biggest deals — CoreWeave and Kratos — totaling over $42 million — demonstrate serious intent. It’s interesting to watch how professionals play these market turns.
