Micron Technology (NASDAQ: MU) and SanDisk (NASDAQ: SNDK) shares edged lower in pre-market trading on Wednesday, pulling back from Tuesday's sharp advances as market participants reassessed the extent to which recent gains already reflect the bullish outlook for memory chips.
Micron was down roughly 1.1% before the opening bell, while SanDisk slipped about 0.5%. The modest declines follow a 6.8% jump for SanDisk and a 5% gain for Micron on Tuesday, moves that extended a rally driven by tight supply conditions and surging demand from artificial intelligence applications.
Tuesday's rally raises the bar
SanDisk's surge came after Rosenblatt analyst Kevin Cassidy initiated coverage with a Buy rating and a $2,400 price target. Cassidy's thesis centers on AI fundamentally altering the economics of NAND flash memory. He argued that emerging computing platforms are shifting flash from a commodity storage medium to a more system-critical component of AI infrastructure, where performance, density, endurance, and supply certainty take on greater importance.
That perspective helped push SanDisk to $1,887.04 on Tuesday, leaving the stock up more than 600% year-to-date. SanDisk has also disclosed agreements with eight customers that are expected to cover about half of its fiscal 2027 bit production and roughly two-thirds in fiscal 2028, providing greater earnings visibility.
However, these supports also raise the hurdle for future performance. When a stock has multiplied several times over, investors are no longer merely asking whether conditions are improving; they are questioning whether results can continue to exceed market expectations.
Micron faces an expectations problem
Micron has its own near-term test when it reports fiscal fourth-quarter results on September 30. Stifel analyst Brian Chin remains constructive, arguing that supply constraints should keep pricing and margins elevated even as growth moderates. He projects Micron's revenue to rise about 22% sequentially in the fourth quarter, then slow to around 11% growth in the following quarter.
That deceleration does not imply a downturn, but it does illustrate why the stock may become more sensitive to expectations. Beth Kindig of I/O Fund has made the point more directly: “In all likelihood, the 343% YoY growth rate recently reported is in the rearview mirror,” she wrote, referring to Micron's latest DRAM revenue growth.
Micron's fiscal third-quarter DRAM revenue reached $31.3 billion, up 343% from a year earlier, while average selling prices jumped sharply. Numbers that large create difficult comparisons for the company to beat.
The cycle is strong but surprises matter more
Evidence supporting the memory thesis remains substantial. Micron has said demand continues to exceed supply, and management expects industry conditions to remain tight beyond 2027. AI workloads are increasing demand for HBM, conventional DRAM, and storage, stretching capacity across the industry.
SanDisk is making a similar argument in NAND. Its multiyear customer agreements are designed to reduce the volatility that historically made flash memory one of the semiconductor industry's most cyclical businesses.
As the market digests these dynamics, the near-term direction for both stocks may hinge on whether upcoming earnings and guidance can match the elevated expectations that Tuesday's rally has set.
