In a series of dynamic investment maneuvers, Cathie Wood's Ark Invest has recalibrated its portfolio, significantly boosting its stake in Alibaba Group Holding Ltd. while concurrently reducing its positions in Advanced Micro Devices Inc. and Tempus AI Inc. These trades reflect Ark Invest's strategic responses to evolving market dynamics and corporate developments within the technology sector, particularly in artificial intelligence.
Detailed Report: Ark Invest's Recent Market Activities
On Wednesday, September 24, 2025, prominent investor Cathie Wood, through her firm Ark Invest, undertook several key trading actions. The ARK Innovation ETF (ARKK) fund acquired 63,231 shares of Alibaba Group, representing an investment of approximately $11.16 million. This substantial purchase coincided with a significant rise in Alibaba's stock price, which closed up 8.19% at $176.44. The increased interest in Alibaba follows an announcement by CEO Eddie Wu regarding the company's intensified commitment to expanding its artificial intelligence investments, a move anticipated to stimulate global AI spending and foster Alibaba's future growth.
Conversely, Ark Invest opted to divest a considerable portion of its holdings in Advanced Micro Devices (AMD). The ARKK fund sold 138,432 shares of AMD, with the transaction valued at around $22.3 million. AMD's stock experienced a marginal decline of 0.01%, closing at $160.88. This divestment occurred despite AMD's recent collaboration with Cohere, aimed at enhancing enterprise AI capabilities through its Instinct GPUs. This partnership is designed to offer scalable and secure AI solutions to businesses and governmental entities, strengthening AMD's position in the data center and AI markets.
Furthermore, Ark Invest reduced its exposure to Tempus AI Inc., selling 45,299 shares from the ARKK fund, totaling approximately $3.6 million. This sale follows a recent downturn in Tempus AI's stock, which saw a 5.82% decrease to close at $79.23. The reduction in stake comes after Tempus AI had previously seen its stock surge due to FDA clearance for its RNA-based device. Ark Invest has been consistently offloading shares of Tempus AI in recent trading sessions.
This sequence of trades highlights Ark Invest's active management approach, continually adjusting its portfolio to capitalize on perceived growth opportunities and manage risks within the rapidly evolving technology landscape. The shifts underscore a selective focus on AI-driven innovation, balancing new investments with profit-taking and re-evaluation of existing positions.
