New York, Feb 14, 2026, 10:04 EST — The market has closed.
- Micron wrapped up Friday’s session at $411.66, slipping 0.6%.
- Capital World Investors disclosed a 5.2% stake as of Dec. 31, according to a filing.
- HBM4 supply cues and memory prices are in focus for traders ahead of Tuesday’s open.
Capital World Investors has taken a 5.2% position in Micron Technology. The memory-chip stock ended Friday at $411.66, slipping 0.56% during the session. 1
The filing hits while Micron’s stock continues acting as a barometer for the memory cycle—and more recently, anything connected to AI hardware demand. Even minor shifts in supply chatter have been enough to swing the stock.
Markets in the U.S. are closed Monday for Washington’s Birthday, meaning Micron and rivals won’t trade again until Tuesday. 2
Micron shares dropped Friday as the broader market lost ground, pulling the Nasdaq, S&P 500 and Dow each into the red. 3
Capital World Investors disclosed a stake of 58,472,522 shares in Micron, representing 5.2% of the company’s common stock, according to a Schedule 13G/A filed Feb. 13. 4
The stock’s been caught up in the high-bandwidth memory race. HBM—short for high-bandwidth memory—is a stacked DRAM built to sit right next to AI chips, pushing data at a faster clip. It’s turned into a turf war for profits between Micron and competitors in Asia. CFO Mark Murphy told MarketWatch that Micron’s HBM4 is now rolling out in volume. “We’re highly confident in our HBM4 product performance and quality and reliability,” he said. 5
Micron management dismissed talk of technical trouble with HBM4, telling Wolfe Research’s conference the company is facing demand “significantly higher” than supply and expects that imbalance to last past 2026, according to Investing.com. The outlet also noted Micron informed investors that HBM4 is already fully booked for calendar 2026 and production yields remain on target. 6
Joseph Moore at Morgan Stanley bumped his price target on Micron up to $450, noting, “As much as happened in the last 12 months in DRAM, we remain excited for what’s ahead.” He flagged more price hikes on the way, with supply unlikely to ease much in 2026. 7
The race is still on. Samsung Electronics confirmed this week it has already shipped its newest HBM4 chips to customers, Reuters reported, as the company works to narrow the gap in AI memory. SK Hynix isn’t sitting out either, flagging its HBM4 roadmap as well. 8
Lenovo, the top global PC maker, flagged that memory shortages are squeezing PC shipments and forcing price hikes to counter rising memory costs, CEO Yang Yuanqing told Reuters. “We expect PC unit sales to face pressure, but believe we can still grow revenue and maintain profitability,” Yang said. 9
The setup isn’t one-sided. Should buyers hesitate as prices climb, or if suppliers push out more product than forecast, the memory market can turn on a dime — and with it, Micron’s margins swing hard.
Tuesday’s session puts Micron and the rest of the memory stocks back in focus, as traders look to see whether momentum from the recent HBM4 supply news holds up. Fresh updates on pricing, customer deals, or major shareholder disclosures could jolt the group again.
