  • The stock has now fallen over 2% Monday and sharply further pre-market Tuesday, as investors reassess memory-chip valuations industry-wide.
  • The selloff follows SK Hynix's plunge below its IPO price and a blockbuster Shanghai debut from Chinese memory maker CXMT, which have reignited fears about Chinese competition.
  • More than $1 billion has reportedly been wiped from memory-chip stocks industry-wide, including SanDisk, Samsung and SK Hynix.
  • Micron carries a market capitalization exceeding $1.02 trillion and a forward price-to-earnings ratio of 4.96, with some analysts arguing the structural undersupply in DRAM through 2028 remains intact.

AI-Memory Selloff Intensifies Across the Sector

Micron Technology (NASDAQ:MU) shares fell sharply in pre-market trading on Tuesday, down more than 7 percent, as an artificial intelligence-memory selloff intensifies following SK Hynix's (NASDAQ:SKHY) plunge below its initial public offering price and a blockbuster Shanghai stock market debut from Chinese memory maker CXMT, which have reignited fears about intensifying Chinese competition in the memory chip market.

Micron is a Boise, Idaho-based global leader in semiconductor memory and storage solutions, designing, manufacturing and selling DRAM, NAND flash, NOR flash and high-bandwidth memory products under its Micron and Crucial brands. The company serves diverse end markets, including cloud and enterprise data centers, personal computing, mobile devices, networking, automotive and industrial electronics, with its advanced memory technologies playing a central role in AI and machine learning applications.

The stock has now extended a multi-day decline, falling more than 2 percent in Monday's session before the sharper pre-market losses on Tuesday, as investors reassess memory-chip valuations across the industry amid reports of China's progress in deep ultraviolet lithography technology and growing concern that hyperscaler AI capital expenditure may be nearing its limits. The selloff has wiped more than $1 billion from memory-chip stocks industry-wide, including SanDisk (NASDAQ:SNDK), Samsung and SK Hynix.

Valuation Reflects Structural Supply Debate

Micron carries a market capitalization exceeding $1.02 trillion and trades at a forward price-to-earnings ratio of 4.96 and a trailing P/E of 19.95, with reported earnings per share of $45.12. Shares have traded in a 52-week range of $103.38 to $1,255.00, reflecting the extraordinary volatility that has characterized the memory sector's AI-driven repricing over the past year.

Even amid the sharp pullback, some analysts argue that the structural undersupply in DRAM through 2028 remains intact, pointing to persistent demand from AI training and inference workloads as a longer-term support for pricing, even as near-term sentiment remains dominated by competitive and macroeconomic concerns.

Conclusion

Micron's sharp decline reflects an industry-wide reassessment of memory-chip valuations amid intensifying competitive pressure from Chinese manufacturers and broader doubts about the pace of AI infrastructure spending. Whether the stock's longer-term structural supply thesis reasserts itself will likely depend on how demand signals from hyperscaler capital expenditure evolve in the coming weeks.
