Cathie Wood’s investment firm ARK Invest executed multiple significant portfolio adjustments in recent days, reducing semiconductor exposure while increasing allocations to artificial intelligence infrastructure and medical technology companies.
The most substantial divestment involved Taiwan Semiconductor Manufacturing Company. Between May 14 and 15, ARK portfolios disposed of 100,549 shares of the chipmaking giant, representing approximately $40.6 million in total value. Despite the sale, TSMC stock has climbed roughly 35% since the beginning of the year. The semiconductor manufacturer recently upgraded its projection for the worldwide chip market to reach $1.5 trillion by decade’s end, revising upward from an earlier $1 trillion estimate, with artificial intelligence and high-performance computing anticipated to drive 55% of that expansion.
Taiwan Semiconductor Manufacturing Company Limited, TSM
TSMC delivered impressive first-quarter 2026 financial results, recording revenue growth of 35.1% and net income expansion of 58.3%. The company’s chief executive characterized artificial intelligence demand as “extremely robust.” Nevertheless, TSMC doesn’t rank among ARK’s ten largest portfolio positions.
ARK concurrently divested approximately 62K shares of Advanced Micro Devices totaling $10.9M, alongside more than 57K Teradyne shares valued at $20.7M. These transactions occurred as the iShares Semiconductor ETF experienced roughly a 4% decline on May 15.
ARK Accelerates AI and Healthcare Investments
Regarding acquisitions, ARK purchased approximately 255K shares of Cerebras Systems, representing one of the fund’s most significant single-week accumulations. Cerebras specializes in manufacturing AI compute infrastructure and has garnered increasing attention from the investment community.
The firm additionally acquired over 162K shares of Tempus AI, an enterprise leveraging artificial intelligence for healthcare applications and diagnostic solutions. ARKK incorporated 132K shares of Intellia Therapeutics and 52K shares of Natera, maintaining its consistent investment approach in precision medicine technologies.
Within the financial technology sector, ARK accumulated nearly 42K shares of Circle Internet distributed across three separate funds, expanding its participation in digital payment systems and cryptocurrency-adjacent financial infrastructure.
ARK further purchased over 61K shares of Kodiak AI and 183K shares of Kratos Defense, extending an established pattern of accumulating defense technology positions.
Fund Performance and Wood’s Market Perspective
The Ark Innovation ETF, ARK’s primary investment vehicle, has decreased 3.81% through 2026 thus far, lagging behind the S&P 500’s performance of more than 8%. Examining a five-year timeframe, ARKK has generated an annualized return of -6.25%, contrasting with the S&P 500’s 13.80%, based on Morningstar data.
Notwithstanding this performance gap, Wood has maintained her long-range investment thesis. She has characterized the present environment as a “great acceleration” propelled by artificial intelligence and related innovations, and has rejected assertions that market conditions resemble a speculative bubble.
“AI training costs are dropping 75% per year,” Wood stated during a recent Bloomberg podcast appearance, noting that inference expenses are declining at an even more rapid pace.
Investor appetite for ARK products remains evident. The Ark Innovation ETF attracted approximately $1.48 billion in net capital inflows during the five-day period ending May 14, according to data from ETF analytics provider VettaFi.
As of May 15, ARK’s largest portfolio allocations comprise Tesla at 11.16%, AMD at 5.57%, and Circle Internet at 5.23%.
