Nebius Stock Jumps After Wall Street Bank Upgrades AI Infrastructure Play

AMD shares have been on fire this year.

Micron Technology (MU) stock has returned 552% over the past twelve months. At near $1,070 a share, has the price run ahead of the business? On the last twelve months of adjusted earnings, meaning normalized net income with stock-based compensation added back, Micron trades at about 23.5 times. That number looks backward, and memory prices have moved too fast for it to show what Micron earns today.

AMD has gained more than 180% this year and recently crossed a $1 trillion market cap.

Advanced Micro Devices, Inc. (NASDAQ:AMD) concluded the September 21 session valued more than $1 trillion for the first time, after its shares increased nearly 10% in a single day to close at $615.52. That type of headline is simple to write and read, but it is nearly useless for an investor deciding what to do […]

The latest $1 trillion chipmaker now costs about 40 times its expected 2027 earnings. Its bigger, faster-growing competitor costs about 15 times its own.

Advanced Micro Devices (NASDAQ:AMD) has been one of the year’s most striking stock stories, with a run that has left the semiconductor sector and the broader large-cap technology sector well behind. The VanEck Semiconductor ETF (NASDAQ:SMH) is up 67% year to date (YTD). The Invesco QQQ Trust (NASDAQ:QQQ) is up 21% over the same stretch. […]

No stock rally is perfect, as is the case with the one seen this week in the tech-heavy Nasdaq Composite.

UBS said it sees data-center infrastructure positioned for “rapid growth” with AI adoption expanding and model developers facing limited computing capacity.

Micron Technology (MU) has returned about 575% over the past twelve months, against 17% for the S&P 500. The past three months added about 4%, so the run has flattened. At a price near $1,100, you would be buying the record profit that boom produced, and contracts that will cap the price of much of Micron's memory once its planned deals are signed.

Nvidia just posted triple-digit revenue growth and Jensen Huang says the company can only fulfill 70% of demand, yet the stock still trades well below where the math points. Three converging forces suggest the gap between current price and fair value may close faster than most investors expect.

Chip stocks have been doing well in recent years due to artificial intelligence (AI), and while Nvidia has typically outperformed AMD, the tide has turned over the past year.

If you hold NVIDIA (NVDA) stock, one number deserves your attention: roughly a quarter. That is the share of fiscal 2028 business management expects from AI labs it will back with its own balance sheet. NVIDIA's revenue more than doubled year over year in fiscal Q2 2027, so this number is easy to miss. An important thing to watch is how much future demand depends on NVIDIA backing its own customers.

Advanced Micro Devices Inc. (NASDAQ:AMD) spent most of the AI boom chasing Nvidia Corp. (NASDAQ:NVDA) from a distance. In 2026, that relationship flipped. AMD shares have surged about 187% this year compared to roughly 22% for Nvidia—a massive 165-percentage-point lead that marks AMD’s widest gap over its rival since ChatGPT launched. The historic shift suggests Wall Street is no longer viewing AMD merely as a low-cost alternative to Nvidia, but is instead revaluing a completely different layer
