New York, Jan 17, 2026, 10:55 EST — Market closed.
- Micron climbed 7.8% on Friday to $362.75, pushing its winning streak in memory-chip stocks even further.
- A Micron director revealed in a filing that they bought about $7.8 million worth of shares.
- Micron kicked off construction on its New York megafab just as the U.S. market enters a holiday-shortened week.
Micron Technology (MU.O) closed Friday 7.8% higher, at $362.75. Shares fluctuated between $346.65 and $365.59, with roughly 48 million traded.
This move is crucial as Micron stands at the heart of investor bets on memory prices and AI-driven chip demand. High-bandwidth memory, a premium DRAM variant paired with AI processors, has turned into a major swing factor for the sector.
The week kicks off shortened by the Martin Luther King Jr. Day holiday, with U.S. markets closed Monday. Earnings season is picking up steam, while chip stocks remain under the microscope following a volatile run for broader indexes, Reuters reports. (Reuters)
A regulatory filing revealed that Micron director Teyin M. Liu purchased 23,200 shares on Jan. 13-14, paying around $336 to $337 per share, totaling about $7.8 million. The filing also showed his direct holdings increased to 25,910 shares following these buys. (Micron Technology)
Micron announced Friday it has broken ground on a $100 billion memory manufacturing campus in Clay, New York. This is part of a larger U.S. expansion the company values at around $200 billion. CEO Sanjay Mehrotra described the project as “building leading-edge memory at scale.” Nvidia’s Jensen Huang emphasized that “advanced memory has become essential” with AI’s rise, while Microsoft’s Satya Nadella called “memory foundational.” Micron aims to start production by 2030, targeting 40% of its DRAM output to come from U.S. facilities.

Micron faces off against Samsung Electronics and SK Hynix in a memory market notorious for sudden swings in supply and prices. These supply challenges have resurfaced as AI systems demand more high-end memory for data centers. (MarketWatch)
Traders face a straightforward question in the short term: will the stock maintain Friday’s gains once liquidity picks up after the long weekend, or will the rally sputter without new catalysts?
Investors are watching how the broader semiconductor sector performs as quarterly earnings come in across tech. Memory stocks, in particular, tend to react to changes in risk appetite just as much as to individual company news.
There is a downside risk. Memory is cyclical, and any shift in pricing momentum or a cutback in big-tech spending could quickly derail expectations and trigger a sharp reset in crowded trades.
Micron’s New York plant won’t start producing for years, leaving the stock to respond to short-term factors: pricing, yields, and how fast customers commit to AI-driven system supplies.
Tuesday, Jan. 20, marks the reopening of U.S. markets. Micron faces its first challenge then: will Friday’s breakout hold, or will profit-taking push it back?
