Cathie Wood’s ARK Invest executed major portfolio adjustments on Tuesday, September 29, 2026. The firm acquired approximately $81 million in Nvidia (NVDA) stock while offloading roughly $110 million in AMD shares. A closer look helps illuminate the motivations behind ARK Invest’s portfolio reallocation.
Why Did Ark Invest Sell AMD And Purchase More Nvidia Stock?
Data indicates that ARK acquired 356,681 shares of Nvidia (NVDA) spanning four distinct Exchange Traded Funds (ETFs). This acquisition follows Nvidia’s announcement that its board expanded its share-repurchase authorization by $150 billion, bringing its total buyback capacity to $235 billion through fiscal 2028. Numerous analysts interpret this authorization expansion as a strong statement of confidence from the company’s board.
Even as ARK boosted its stake in Nvidia (NVDA), it significantly trimmed its position in Advanced Micro Devices, Inc. (AMD). The firm liquidated 181,767 shares of AMD across four separate ETFs.
During 2026, Nvidia’s (NVDA) stock has climbed roughly 22%. By comparison, AMD has surged approximately 184% over the same period. This divergence suggests ARK may be locking in profits on AMD while anticipating superior returns from Nvidia through the remainder of the year.

Both Nvidia (NVDA) and AMD stand out as primary beneficiaries of the artificial intelligence boom. Nvidia (NVDA) maintains its dominant market leadership, with its market capitalization reaching a record $5.56 trillion in September 2026. Similarly, AMD achieved substantial milestones last month, driving its stock to a peak of $615.52 and pushing its market cap past the $1 trillion threshold.
While Wall Street analysts maintain a growing bullish outlook for both Nvidia (NVDA) and AMD to sustain their upward trajectories, a segment of analysts remains concerned about a possible AI bubble, warning that any collapse could trigger serious fallout across the broader stock market.
