Tracking Cathie Wood: A massive portfolio shake-up! Cathie Wood purchased nearly 1.5 million shares in the 'low-altitude economy' dual leaders, added to positions in Alibaba and CoreWeave; aggressively sold off traditional SaaS

U.S. time on Tuesday, the three major U.S. stock indexes collectively closed lower as investors worried about the potential for continued escalation of conflicts in the Middle East; however, all indices rebounded significantly from their intraday lows.

From the overnight session, it was observed that ARK conducted an unusually large-scale portfolio overhaul, ruthlessly shedding nearly 4 million shares of traditional social networking assets while deploying funds across multiple fronts to aggressively invest in 'low-altitude economy' (eVTOL), AI cloud infrastructure, and cutting-edge biotechnology.

Buying focus: Betting on eVTOL and future mobility,

The March 3 buying list was not only large in quantity but also highly strategic and aggressive, with funds heavily concentrated in three sectors expected to experience non-linear explosive growth.

eVTOL and Future Mobility: Aggressively Accumulating the 'Flying Robot' Platform

Operation: Massive one-day purchases of electric vertical takeoff and landing (eVTOL) leaders — $Archer Aviation (ACHR.US)$ 947,900 shares, $Joby Aviation (JOBY.US)$ 539,100 shares, while adding to positions in $Tesla (TSLA.US)$ 21,100 shares.

In-depth Analysis: Combining observations on the evolution of the robotics industry, eVTOL is essentially a 'large carrier' that integrates autonomous driving with three-dimensional space. As core components (such as high-energy-density batteries and lightweight materials) gradually mature, using the entire machine as an application carrier to complete the commercial closed-loop is key to building extremely high industry barriers. ARK's purchase of nearly 1.5 million shares in ACHR and JOBY reflects a high-probability bet on the low-altitude economy and the next-generation mode of transportation.

AI Infrastructure and Cloud Ecosystem: Dual-Driven by Computing Power and Data

Operation:Increasing holdings in pure AI cloud computing power providers $CoreWeave (CRWV.US)$ 77,700 shares of the all-flash data storage giant $Everpure (P.US)$ 22,800 shares, with significant additional purchases $Alibaba (BABA.US)$ 138,300 shares and $Amazon (AMZN.US)$ 62,600 shares.

In-depth Analysis: In the AI infrastructure sector, the investment focus is becoming highly multidimensional. The front end consists of CRWV’s direct scheduling of massive GPU clusters for computational networks, while the back end involves PSTG's storage arrays addressing bottlenecks in model training data throughput. Meanwhile, increasing holdings in Alibaba and Amazon reflects capital reassessing the value of giants with vast cloud computing platforms and proprietary data ecosystems.

Frontier Medicine and Brain Science: Searching for the Next Genetic-Level Disruption

Action: Aggressively buying mental health biotech companies $AtaiBeckley (ATAI.US)$ 640,300 shares, $COMPASS Pathways (CMPS.US)$ 270,800 shares; while continuing to add positions in the gene-editing leader $Intellia Therapeutics (NTLA.US)$ 184,100 shares and AI healthcare data company Tempus AI (TEM) 112,500 shares.

In-depth Analysis: ARK's holdings in the healthcare sector are undergoing a dramatic 'metabolism.' The large-scale purchase of ATAI and CMPS, companies focused on novel mental therapies, indicates its search for breakthroughs in cognitive science beyond traditional targeted drugs. The combination of TEM and NTLA reflects continued bets on how AI computing power is reshaping foundational gene design and diagnostic systems.

Sell side:

On the sell side, ARK has wielded its axe towards the 'attention economy,' abandoned by era-related dividends, as well as key hardware components facing cyclical revaluation.

Nextdoor and Roku: The ruthless run on the attention economy

Action: Massive sell-off on community social platforms $Nextdoor Holdings (NXDR.US)$ , with up to 3.95 million shares sold, ranking at the absolute top of the day's sell list; simultaneously reducing holdings in streaming media hardware $Roku Inc (ROKU.US)$ by 336,500 shares and image-based social media $Pinterest (PINS.US)$ by 257,600 shares.

In-depth Analysis: The sale of nearly 4 million shares $Nextdoor Holdings (NXDR.US)$ represents a textbook 'disastrous divestment.' As AI recommendation algorithms and short-form videos increasingly consume users' time, traditional text-image social media and streaming entry points are facing severe traffic saturation and monetization anxiety. These assets, lacking robust AI catalysts, are being thoroughly marginalized by ARK.

Taiwan Semiconductor: Tactical realization amid the semiconductor cycle

Operation: Reduction of 40,500 shares in the leading wafer foundry $Taiwan Semiconductor (TSM.US)$ .

In-depth analysis: Selling Taiwan Semiconductor does not indicate bearishness on AI hardware, but rather appears to be a tactical profit-taking move after the market has fully priced in expectations of full capacity for advanced packaging (such as 2.5D/CoWoS). In the game of capital expenditure cycles, reallocating chips from the highly certain but less flexible wafer manufacturing side to more explosive sectors like computational cloud (CoreWeave) or optical communication is a common way to improve capital efficiency.

Baidu and Traditional SaaS: Repeated Logic and Revaluation

Action: Reduce holdings $Baidu (BIDU.US)$ 101,600 shares, continue selling $PagerDuty (PD.US)$ 94,100 shares and $Salesforce (CRM.US)$ 100 shares.

In-depth Analysis: Baidu was just bought a few days ago, and now it's being reduced again, showing that ARK is still grappling with selecting targets for 'full-body intelligent carriers.' The commercialization slope of Robotaxi might be one of the variables they are considering. Meanwhile, the continued liquidation of PD and CRM once again confirms that traditional enterprise software without AI Copilot revenue growth will inevitably face a downward shift in valuation.
