Quick overview
- Micron Technology’s stock is down 2.42% in pre-market trading, following a significant decline of 14.6% over the past week.
- The selloff was triggered by CXMT’s announcement of a new DDR5 memory module, raising concerns about competition in the DRAM market.
- Labor disputes at Micron’s Taiwan plants could impact operations, although management believes a short strike would have minimal revenue effects.
- Despite current pressures, Micron’s fundamentals remain strong with record earnings and a positive outlook for fiscal Q1 2027.
Micron Technology (NASDAQ: MU) is trading near $883.01 in pre-market action today, down 2.42% after Monday’s 2.97% rebound to close at $904.90. The stock fell 5.63% Friday to $878.84, ending a week in which it lost about 14.6% from $1,029 on October 9. Its market value is about 28% below its June 25 close of $1,213.56, but up about 385% from a year ago and valued at about $1.02 trillion.
CXMT’s 4F² Memory Push Triggers the Selloff
The downward trend has started since China-based ChangXin Memory Technologies (CXMT) announced at a conference in Shanghai on October 9-10 that it would launch a 4F² cell designed DDR5 server memory module by the end of this year. TrendForce estimates that in the second quarter, CXMT had 9.5% DRAM revenue, while Micron represented 23.3%. DRAM also made up approximately 73% of Micron’s fiscal fourth-quarter revenue.
The rising costs of financing have introduced another layer of worry into the construction of AI data centres. Several analysts believe the sell-off was overdone: Fundstrat’s Kent Fung described it as a buying opportunity, noting CXMT’s design would not challenge the high-bandwidth memory found in AI servers, while Rosenblatt’s Kevin Cassidy said it overestimates the immediate competitive threat.
Taiwan Strike Risk Returns to Focus
The labor dispute at Micron’s Taiwan plants remains unresolved. Earlier this month, over 99% of the members of the Taoyuan union approved a strike to call for 15% of operating profit to be transferred to workers. There are conflicting reports on the date of the strike: Invezz has reported that this strike will happen on Thursday, October 22, and TradingKey has stated that there is no date set. A mediation session involving Taichung workers is scheduled for the same day. A short strike could have minimal impact on the revenue outlook, given that more than 75 percent of fiscal 2027 shipments are already booked, management said in September.
Fundamentals Remain Strong
On the revenue side, Micron’s fiscal Q4 results, released on September 30, recorded a record revenue of $54.2 billion, an increase of 379% year over year, and a non-GAAP EPS of $33.42, as well as a record 87% gross margin. The company’s revenue for fiscal Q1 2027 is estimated at $61.5 billion, with an EPS of $38.15 and a gross margin of around 86.25%. Much of HBM is booked for calendar 2027 and management anticipates that memory will remain in short supply through 2028. The stock is valued at about 12 times earnings. Additionally, Micron has increased its buyback authorization to $35.16 billion, which becomes available beginning Dec. 9.
What to Watch Next
Broadly speaking, the picture has become less positive: The trendline has turned down from April and the moving averages have begun to trend lower; the 14-day RSI just dropped into oversold territory around 26.7. Support sits at $856.69, followed by the June low of $738.72. Resistance starts at $972.76, the gap-down level, followed by $982 to $997 and $1,030. Memory pricing is expected to be holding up as SK Hynix is set to report on October 28. So, until then, Micron stocks will be sensitive to any news from CXMT, Taiwan labor negotiations, and sentiment on spending on AI.

FAQs
What’s causing Micron to decline?
China’s CXMT announced a new DDR5 design and it’s impacting micron shares. Selling pressure has been further fueled by Taiwan labour issues and worries over AI data-center investments.
What do you think about the future of Micron?
However, Micron’s fundamentals are bolstered by record earnings, healthy HBM demand and outlook for Q1. But uncertainty about labor and falling technical indicators could keep shares volatile, albeit, given the nature of CXMT competition, that’s a big maybe.
Bottom Line
The situation of Micron is near-term pressured by CXMT’s memory hopes, Taiwan strike dangers and weakening technical signs. But record earnings, high bandwidth memory demand and rosy fiscal Q1 outlook remain positive for the company. Investors will watch the $856.69 support level, upcoming SK Hynix results and developments in Taiwan’s labor talks. Micron’s long-term growth prospects remain underpinned by AI infrastructure, but the prospect of competition and higher expectations could lead to further volatility in the near term.
