Cathie Wood’s ARK Invest made substantial portfolio adjustments on February 4, purchasing chip and electric vehicle stocks while reducing semiconductor testing exposure. The trades were disclosed through daily fund reports.
The firm acquired 141,108 shares of Advanced Micro Devices across multiple exchange-traded funds. The total purchase value reached $34.16 million. AMD stock dropped more than 17% in Wednesday trading despite reporting fourth-quarter results that beat analyst forecasts.
Advanced Micro Devices, Inc., AMD
Investors sold AMD shares after management commentary on near-term artificial intelligence chip demand. Wood’s team purchased shares at the lower price point. The move suggests ARK remains optimistic about AMD’s position in the AI processor market.
ARK bought 35,766 Tesla shares through the ARK Space Exploration ETF for $15.09 million. The electric vehicle stock closed down 4% at $406.01. The purchase adds to ARK’s existing Tesla holdings as the company expands its autonomous driving and robotics divisions.
AI Healthcare Investment Grows
The fund purchased 407,950 Tempus AI shares worth $22.83 million. Tempus AI operates in the healthcare data analytics space using artificial intelligence. This transaction represents one of ARK’s larger single-stock purchases on Wednesday.
ARK also acquired 36,065 shares of GeneDx Holdings for $3.43 million. The fund added 37,379 Kodiak AI shares to its portfolio. These purchases demonstrate continued interest in AI-driven technology companies.
Semiconductor Testing Stock Exit
ARK’s largest sale involved Teradyne stock. The firm sold 258,001 shares across its ETF lineup for $73.01 million. This continues a multi-day trend of reducing the semiconductor testing equipment position.
Teradyne has been a consistent sell for ARK over recent trading sessions. The February 4 sale represents the biggest single-day exit from the stock. ARK appears to be rotating capital away from testing equipment manufacturers.
Digital Advertising Holdings Reduced
The fund sold 190,830 Global-E Online shares valued at $6.47 million. ARK also trimmed 156,758 Trade Desk shares for $4.26 million. Both companies operate in the digital commerce and advertising technology sectors.
ARK sold 107,092 Pinterest shares during the session. These sales show portfolio rebalancing across technology stocks. The firm appears to be concentrating positions in semiconductor manufacturers and AI applications rather than advertising platforms.
The trading activity reflects ARK’s strategy of buying stocks during price declines. Both AMD and Tesla fell on February 4 when ARK made its purchases. This approach matches Wood’s stated philosophy of adding to positions during market weakness.
The Teradyne sale proceeds appear directed toward chip makers and AI companies. ARK shifted from semiconductor testing equipment to companies producing AI processors and healthcare analytics tools. The fund’s February 4 trades totaled over $150 million in buy and sell transactions.
