Micron stock reversed after briefly reclaiming $1,000, falling nearly 6% below $900 as China’s rising semiconductor capabilities, a blockbuster CXMT debut, and growing fears over excessive AI-related investment intensified selling across the memory sector.
Micron Stock Slumps Below $900 as China Semiconductor Threats Trigger Fresh Selloff
Micron Technology shares came under heavy selling pressure after an attempted recovery quickly failed, with the stock retreating nearly 6% and falling back below the $900 level.
The reversal followed a brief move above $1,000 last week, highlighting the growing volatility surrounding memory stocks as investors reassess China’s rapidly developing semiconductor industry and the sustainability of the broader AI investment boom.
The latest selloff was triggered by a combination of developments, including the blockbuster stock market debut of Chinese memory chipmaker ChangXin Memory Technologies (CXMT) and reports that China has begun manufacturing domestically developed deep ultraviolet (DUV) lithography machines.
Together, the developments have raised concerns that China may be closing the semiconductor technology gap faster than previously expected.
Memory Stocks Hit by China Fears
Micron was not alone in suffering heavy losses.
SanDisk shares plunged more than 12%, while U.S.-listed shares of South Korea’s SK Hynix dropped nearly 9%.
The weakness reflects growing fears that Chinese semiconductor companies could eventually become serious competitors across key memory markets.
The broader chip sector is also under pressure. Nvidia, AMD, Intel, Arm and other semiconductor stocks have experienced significant declines as investors reassess elevated valuations and question whether the extraordinary AI spending cycle can continue indefinitely.
Weakness across Korean and Japanese technology stocks has further reinforced the negative sentiment, suggesting that the latest pressure is spreading across global semiconductor markets.
CXMT Raises Long-Term Competitive Risks
The rapid expansion of ChangXin Memory Technologies represents one of the biggest longer-term concerns for Micron investors.
CXMT continues to expand its DRAM production capabilities, while reports that Apple is testing CXMT memory products for devices sold in China have increased concerns about the potential growth of domestic Chinese suppliers.
The immediate impact on Micron’s business is likely to remain limited.
However, the longer-term threat could become more significant if Chinese manufacturers continue improving their technology and increasing production capacity.
Greater competition could eventually weaken pricing power and put pressure on margins, particularly when global memory supply is already expanding.
Nio’s reported $23.3 million investment in CXMT has also highlighted the growing support behind China’s efforts to build a stronger domestic semiconductor ecosystem.
For Micron shareholders, the concern is therefore not simply about current earnings. The bigger question is whether Chinese competitors could eventually challenge Micron’s market share and pricing power.
Technical Strength Meets Near-Term Valuation Questions
From a technical perspective, Micron’s fall below $311 in March and the quick rebound off the 100 daily SMA (green) was symbolically important. Buyers came back as broader stock market sentiment improved. As a result, we have seen a strong rebound and buyers have pushed MU stock above the $1,000 level in early June, reaching $1,210 which was broken yesterday.
We saw a pullback under $1,000 and MU stock slipped to $864, although the 20 SMA (gray) held as support again on the daily chart and we saw a rebound from there early last week. But now the 50 SMA (yellow) has been broken at $900, which opened the door for further losses toward to $800.

Heavy Investment Creates Oversupply Risks
Micron is also investing aggressively to expand its U.S. manufacturing footprint, with major projects planned across New York, Idaho and Virginia.
The company expects rising demand from AI infrastructure, cloud computing and hyperscale data centers to justify this expansion.
However, Micron is operating in an industry where competitors are also rapidly increasing capacity.
The semiconductor sector is entering a massive capital spending cycle as manufacturers race to meet expected demand from AI and advanced computing.
This creates a potentially dangerous imbalance.
If AI infrastructure spending eventually slows before new production capacity is fully absorbed, the memory market could face excess supply.
That could trigger weaker prices and declining margins, reviving the boom-and-bust dynamics that have historically plagued the memory industry.
Micron Stock Faces a More Difficult Backdrop
Micron’s failed recovery above $1,000 has weakened its technical picture, with the stock now back below $900.
The sharp reversal suggests that buyers remain reluctant to defend elevated valuations while concerns over Chinese competition and semiconductor oversupply continue to grow.
Although AI and data center demand remain important long-term growth drivers, investors are becoming increasingly focused on whether the current spending boom can support the enormous expansion in global semiconductor capacity.
For now, Micron faces a more hostile market environment. A sustained break below $900 could expose the stock to further downside as investors reassess the strength of the memory cycle and the growing competitive threat from China’s rapidly expanding semiconductor industry.
