Key Takeaways:
Micron and SanDisk shares rose in early trading Monday as investors bought a 30% decline from June records, betting persistent DRAM shortages outweigh near-term supply glut fears.
Micron Technology Inc. and SanDisk Corp. rebounded 3% and 2.5% respectively in premarket trading Monday as dip buyers stepped in after a punishing sell-off erased roughly 30% of the memory chip sector's value from June peaks.
"The sell-off looks like a sentiment wobble in a still-tight memory market," Fabio Bassi, cross-asset strategist at JPMorgan, said. He described the decline as a temporary correction rather than the end of the AI-driven rally, noting that memory stocks had become highly concentrated positions where small sentiment shifts produce outsized moves.
The Philadelphia Semiconductor Index entered bear market territory Friday after falling more than 20% from its June peak. Micron ended the week at $848.34, down 26.5% from its $1,154 record, while SanDisk retreated more than 28% from its June 25 high after surging more than 600% in 2026. The sell-off was triggered by multiple catalysts: TSMC's capital expenditure guidance of $60 billion to $64 billion, a planned $8.55 billion initial public offering from Chinese competitor ChangXin Memory Technologies, and SK Hynix's 15% plunge on its July 10 Nasdaq debut.
The rebound tests whether the correction created an entry point or signaled the start of a downcycle in a notoriously cyclical industry where shortages have historically triggered overbuilding and falling prices.
Shortages Keep the Bull Case Alive
KeyBanc analyst John Vinh said supply-chain checks in Asia show "memory shortages remain persistent," with tight conditions expected through 2027. KeyBanc forecasts DRAM prices rising 15% to 20% sequentially in the third quarter and another 15% in the fourth, while NAND prices could jump 30% to 40% this quarter followed by a further 15% increase.
Micron, which derives the majority of its revenue from DRAM and high-bandwidth memory used alongside AI accelerators, has shifted its business model toward Supply Commitment Agreements that now represent nearly 50% of total revenue, according to DA Davidson. The contracts reduce the company's exposure to spot price volatility that has historically defined the memory cycle.
SanDisk's long-term customer agreements are creating a "new memory paradigm," Evercore ISI analyst Amit Daryanani said, improving visibility into revenue and cash flow while clean-room capacity remains constrained. SanDisk reported third-quarter revenue of $5.95 billion, up 251% year over year, with gross margins reaching 78.4% and capital expenditure at just 1.4% of revenue — a capital efficiency that would have been unthinkable in prior cycles.
The Boom Creates Its Own Risk
The same shortages supporting prices are encouraging enormous investment that could sow the seeds of the next downturn. Samsung and SK Hynix have outlined hundreds of billions of dollars in new manufacturing projects, while Micron recently raised its planned United States investment to more than $250 billion through 2035. Morgan Stanley estimates China could provide about 30% of net DRAM wafer additions through 2028.
Higher memory prices also raise the expense of AI infrastructure, increasing pressure on hyperscalers already being asked to prove returns on massive capital budgets. CoreWeave, a cloud infrastructure provider, was reportedly examining financial instruments to protect against potential memory chip price deterioration — a defensive posture that raises questions about near-term pricing momentum.
Top-tier analysts remain bullish despite the pullback. Citi holds a Buy recommendation with a $1,400 price target and placed Micron on its 90-Day Upside Catalyst Watch List. TD Cowen projects a $1,600 target, citing supply constraints extending past 2027 and DDR average selling price expansion exceeding 15% in the third quarter. UBS forecasts DRAM undersupply persisting through at least the second quarter of 2028, with 2027 demand expansion of 36.2% year over year outpacing supply growth of just 19.3%.
Skeptics are present. Investor Michael Burry established put positions around $1,052 on July 1, near all-time highs, and insider dispositions reached their most elevated level since 2010, with Director Lynn Dugle selling approximately $1.5 million in shares on June 30.
Micron shares, trading at roughly 6 times forward earnings estimates, have critical support at $813 to $825, where weekly trend support intersects with recent daily selling. A close below $786 would represent a more troubling technical development. The company's next earnings release is scheduled for September 22.
