Micron stock surges 815% as memory chip shortage persists

What happened

Micron Technology stock has risen 815% over the past year, and billionaire David Tepper's Appaloosa Management fund added more shares in Q1 because of bullish outlook. Nebius Group, a neocloud company, posted 684% revenue growth in Q1 and is backed by Nvidia, which holds only seven stocks as a company and has agreed to give Nebius early access to new technology.

Why it matters

Micron is thriving from a memory chip shortage affecting both NAND and DRAM (two types of memory used in data centers), pushing prices higher and boosting revenue and earnings. Nebius is contributing to that same shortage by expanding its data center footprint. Wall Street analysts predict memory chip supply won't ease in 2027 and expect Micron's revenue to rise 66% next year, while Nebius is projected to reach $11.2 billion（約1.8兆円） in revenue by the end of 2027—more than 10 times its current trailing-12-month total of $878 million（約1400億円）.

What to watch

Micron trades at less than 19 times forward earnings, below the S&P 500's 22 times forward earnings, offering potential upside if growth extends into 2027. Nebius analysts estimate 550% revenue growth this year and 225% next year, positioning it to emerge as a top AI-focused cloud company if it meets those expectations.
