Cathie Wood’s ARK Invest made some substantial changes to its portfolio on Tuesday, September 29, 2026. The investment firm reportedly purchased $81 million worth of Nvidia (NVDA) stock, while selling about $110 million worth of AMD shares. Let’s discuss why ARK Invest may have decided to reshuffle its portfolio.

Why Did Ark Invest Sell AMD And Purchase More Nvidia Stock?

According to reports, ARK bought 356,681 shares of Nvidia (NVDA) across four of its ETFs (Exchange Traded Funds). The purchase comes on the heels of Nvidia’s board expanding its share-repurchase authorization by $150 billion. The move brought the capacity to a total of $235 billion through fiscal 2028. Many analysts are viewing the expansion as a vote of confidence from the board.

While ARK increased its Nvidia (NVDA) exposure, it has drastically reduced its Advanced Micro Devices, Inc (AMD) holdings. The investment firm sold 181,767 shares of AMD across four ETFs.

Nvidia’s (NVDA) stock value has risen by about 22% in 2026. AMD, on the other hand, has risen by about 184% in the same time frame. It is possible that ARK is booking its AMD profits, while expecting Nvidia to deliver bigger gains for the rest of the year.

Both Nvidia (NVDA) and AMD have been among the biggest gainers of the AI boom. Nvidia (NVDA) is the clear market leader, with its market cap hitting an all-time high of $5.56 trillion in September 2026. AMD also saw incredible gains last month, with stock price hitting a peak of $615.52, with its market cap finally breaching the $1 trillion.

Nvidia (NVDA) and AMD are expected to continue its upswing, with Wall Street analysts growing increasingly bullish on both companies. However, many analysts worry about a potential AI bubble, the bursting of which could have severe consequences for the stock market.

Advanced Micro Devices, Inc (AMD) continues to be a favorite among Wall Street analysts. Wells Fargo has reiterated its stock price target for AMD to $700, with a 15.21% upside, while Bank of America has revised its outlook to $720, an 18.50% upside. Both institutions have also maintained their “buy” ratings for the the stock. Let’s discuss why Wall Street continues to be bullish on AMD and what the future holds for the company.

Why Is Wall Street Raising Its Stock Price Target For AMD?

Wall Street’s latest revision for AMD’s stock price comes on the heels of the company announcing the acquisition of World Labs in a $8.2 billion deal. World Labs is an expert in spatial intelligence, and the acquisition will likely further AMD’s AI ventures.

AMD has also delivered stellar results over the last year. Revenue and earnings per share have risen significantly, and Wall Street analysts anticipate the pattern to continue over the coming years. Many expect even higher revenue in the next quarter driven by AMD’s latest Helios chips.

The bullishness around AMD’s stock performance also reflects in its recent rally to a new all-time high of $615.52 last week. The company’s market cap also breached the $1 trillion mark for the first time in its history. AMD has since faced a correction to the $607 mark, and may enter a sideways trajectory, given the overarching poor economic conditions. The Federal Reserve decided to raise interest rates earlier this month to combat rising inflation amid volatile oil prices. The US and Iran are yet to reach a deal, before which oil prices may continue to be unstable.

Nonetheless, the current trend of building data centers for AI may continue to feed AMD’s coffers. The company is expected to remain on its upward trajectory, at least for the time being.
