Micron reaches historic high, driven by surging AI memory demand.
Micron Technology has reached all-time highs in a shortened trading week. The memory chip manufacturer has attracted increasing attention from Wall Street ahead of its June 24 earnings report, with stock gains continuing to expand.
U.S. stock markets did not trade on Friday due to Juneteenth, and Nasdaq did not open on Saturday. This set Micron's final regular closing price at $1,133.99 on Thursday. Trading volume that day reached 64.3 million shares, with a high of $1,149.43.
The timing is shifting. Investors are closely watching Micron's third quarter data to understand whether AI data center spending continues to drive chip demand, pricing, and margin growth. According to Reuters, Micron stock has risen 298% year-to-date. The Philadelphia Semiconductor Index has reached all-time highs, with weekly gains of 7%.
Micron stock showed significant volatility this week. The stock rose 10.84% on Monday, fell 6.18% on Tuesday, rose 2.20% on Wednesday, and then surged 8.70% on Thursday, all based on daily closing prices. There were no signs of quiet accumulation—traders rushed in ahead of new data release, scrambling for scarce liquidity.
Micron has set itself challenging revenue targets. As early as March, the company indicated it expected third quarter revenue of $33.5 billion, within a range of $750 million. The company also forecast non-GAAP earnings per share of $19.15, within a range of 40 cents. Non-GAAP figures exclude certain items that management does not believe reflect actual operating results.
Micron CEO Sanjay Mehrotra stated at the time that the company reached new highs in revenue, gross margin, earnings per share, and free cash flow, adding that in the AI era, "memory has become a strategic asset." This comment partly explains why the stock has been re-rated—investors now view DRAM, NAND, and high-bandwidth memory as critical hardware rather than just another part of the memory cycle. DRAM handles computational working data, NAND retains data during power outages, and high-bandwidth memory (HBM) sits adjacent to AI chips to enable faster data transfer.
Andy Pratt, investment strategy director at Burney Company, told Reuters: "There's tremendous momentum here lately." He indicated there remains "significant potential" in revenue surprise signals. Steve Kolano, chief investment officer at Integrated Partners, described Micron's situation as "a classic positive feedback loop," stating that semiconductor demand is "extremely robust" relative to production capacity.
SK Hynix has not stood aside. The company said this week that it has sent samples of its 12-layer HBM4E chips to major customers. The new chips can achieve 16 gigabits per second per pin, with power consumption expected to be more than 20% lower than older versions. According to Reuters, SK Hynix is a major HBM supplier to Nvidia, with Samsung and Micron also attempting to capture business in this space.
Demand is no longer coming solely from cloud servers. Barron's reported Thursday that Micron stock received a boost after Apple CEO Tim Cook discussed higher memory and storage costs, suggesting that DRAM and NAND supply is tight for both large consumer electronics companies and AI infrastructure buyers.
The current risk is that stock prices may have risen too much. Reuters states valuations are high, with the Federal Reserve's preferred inflation indicator set to be released next week, along with a final assessment of first-quarter GDP. Both could shift market sentiment. Drew Matus of MetLife Investment Management told Reuters that due to wealth effects, any factors that could threaten AI trade or stocks are being closely watched.
Micron will report its third quarter financial results on Wednesday, June 24, with a conference call scheduled for 2:30 p.m. Mountain Time and 4:30 p.m. New York Time. Investors want to know how much HBM capacity has been booked, how long DRAM and NAND pricing can be sustained, and what kind of guidance management can provide for the next leg of gains.
