NEW YORK, December 30, 2025, 07:04 ET — Premarket
- Micron shares were up 1.1% in premarket trading, after a 3.4% rise in the prior session
- A new SEC filing showed Micron’s CFO moved 35,000 shares into an estate-planning trust
- Fed minutes and export-control headlines are in focus for rate-sensitive chip stocks
Micron Technology, Inc. (MU) shares rose 1.1% in premarket trading on Tuesday to $297.57, after the stock climbed 3.4% to close at $294.37 in the prior session, as investors weighed a fresh insider filing. MarketWatch
The disclosure matters now because Micron’s sharp run into year-end has made traders quick to scrutinize any insider transactions for signals about confidence in the rally.
It also comes with chip stocks trading as a referendum on AI infrastructure spending, while investors brace for a light-liquidity week that can amplify moves.
A filing showed Micron’s executive vice president and chief financial officer, Mark Murphy, transferred 35,000 shares on Dec. 24 into a grantor retained annuity trust (GRAT), an estate-planning vehicle. The filing listed the transfer price as $0 and said Murphy and his spouse serve as trustees.
Micron has been a focal point in the memory group as demand for advanced chips used in data centers tightens supply and lifts pricing power.
Earlier this month, Micron forecast second-quarter adjusted profit of $8.42 per share, plus or minus 20 cents, and revenue of $18.7 billion, well above analyst expectations, as the company pointed to strong AI-driven demand for memory. Reuters
That guidance spotlighted high-bandwidth memory, or HBM — a type of dynamic random-access memory that stacks chips to move data faster and use less power — where Micron competes with Samsung Electronics and SK Hynix. Reuters
Policy headlines are also on watch. The United States approved Samsung and SK Hynix shipments of chipmaking tools to their China plants for 2026, Reuters reported, a development investors may factor into assumptions about industry capacity and supply.
Macro remains a near-term driver for rate-sensitive tech. Investors are awaiting minutes from the Federal Reserve’s Dec. 9-10 meeting, when it cut rates by 25 basis points, and volumes are expected to stay light with U.S. markets shut on Thursday for New Year’s Day, Reuters reported. “As we near the year end, investors are facing a dilemma,” said Kathleen Brooks, research director at XTB.

For Micron traders, the next test is whether the stock holds recent gains as markets weigh how long the memory supply crunch lasts and how aggressively competitors add capacity.
Any fresh signals on AI data-center buildouts, HBM contract pricing, and capital-spending plans will stay front and center, because small shifts in supply can swing margins sharply in the memory cycle.
