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.

Micron stock (NASDAQ: MU) opened Wednesday’s trading session at $1,065 and remains on the front foot ahead of the Q4 2026 earnings call on September 30, 2026. Wall Street analysts expect the company to beat all earnings expectations and see a surge in value. The market is closely watching the upcoming revenue report, which will dictate MU’s next direction. Most financial strategists expect the major semiconductor company to deliver blockbuster results.

On the heels of the earnings call, global equity research and brokerage firm Bernstein has maintained its buy rating for Micron stock. The financial entity wrote in a note to clients on Tuesday (September 29, 2026) and urged institutional funds to begin taking an entry position in MU. The earnings call will act as a catalyst and make the leading equity surge in price. Taking an entry position even at the $1,065 level could still be profitable to investors.

How High Will Micron Stock Reach?

Mark Li, the stock market analyst at Bernstein, has predicted that Micron stock could reach a new price target of $1,300. That would be a profit of $235 per share if traders take an entry position in the equity today. It also marks an uptick and a return on investment (ROI) of approximately 22% from its current price. Therefore, an investment of $1,000 could turn into $1,220 if the price prediction from Bernstein turns out to be accurate.

Micron stock is among the most sought-after equities in the market for its robust performance. It has risen by nearly 240% year-to-date and made early investors more than triple their money. MU is riding the AI boom, and the cycle could continue up until the end of the decade in 2030. However, semiconductor stocks are highly cyclical and face a harsh downturn when the market is not in their favor.
