Micron Falls 27.5% Despite Record Earnings Amid Sector Memory Sell-Off

Micron Technology Inc. (NASDAQ:MU) plummeted 27.5% in late July 2026 despite reporting record quarterly revenue of $41.46 billion, a 345.72% year-over-year surge, and gross margins of 84.6%. The stock fell from over $1,132 to $820.53, marking a sharp reversal for a company that had seen an 187.67% year-to-date gain. The decline was part of a broader sector-wide selloff triggered by the unexpected rise of Chinese DRAM maker CXMT, which surged 466% on its Shanghai debut and outpaced Intel’s market capitalization. Investors rapidly divested memory and semiconductor stocks, dragging down peers like SanDisk, Western Digital, and SK hynix.

The sell-off intensified after SK hynix, a major South Korean memory chip producer, missed second-quarter revenue and profit estimates despite reporting strong demand for AI-related memory products. The company’s shares fell as shipment delays limited price gains for DRAM chips, even as AI infrastructure investments spurred demand. This created a paradox: while tech firms like SK hynix and Micron faced short-term profit misses, their long-term growth prospects remained tied to the AI industry’s expansion. However, market sentiment turned sharply negative, with chip stocks extending losses amid broader concerns about a potential AI sector bubble.

CXMT’s meteoric rise exacerbated fears of oversupply in the memory market. The Chinese firm competes in commodity DDR5 memory, not the high-bandwidth HBM (high-bandwidth memory) used in AI servers, but investors broadly labeled all memory stocks as risky. Morgan Stanley’s Mike Wilson noted the semiconductor sector correction was “pretty well advanced,” with Micron’s high beta of 2.14 amplifying its volatility. Analysts warned that the market’s focus on short-term cyclical risks overshadowed long-term fundamentals, such as Micron’s strategic customer agreements and its role in supplying HBM4E chips for NVIDIA’s Vera Rubin project.

Despite the turmoil, some analysts remained optimistic about Micron’s long-term potential. Aol.com highlighted that reaching $2,000 per share by 2030 would require a 143.7% gain from its July 2026 price of $820.53. This scenario hinges on a clean HBM4E ramp by 2027, sustained hyperscaler capital expenditures, and containment of CXMT’s impact on commodity DRAM pricing. Wall Street’s consensus target for Micron stood at $1,507.38, with 89% of analysts rating the stock as “buy” or “strong buy.” However, Nomura’s forecast of a 63% surge in DRAM revenue to $2.06 trillion by 2030 contradicted broader market models, suggesting a possible mispricing of the memory cycle’s trajectory.

SanDisk, another key player in the sector, fared even worse, plunging 47.57% over a month despite beating Q3 earnings estimates by 60% and reporting a 645% year-over-year surge in datacenter revenue. China Renaissance analysts projected a 200% upside for SanDisk, citing its position as a pure-play NAND flash supplier for AI infrastructure. The firm argued that SanDisk’s margin expansion, zero long-term debt, and multi-year contracts with hyperscalers could justify a re-rating to AI infrastructure multiples. However, the stock’s sharp decline reflected fears of valuation risks, with options data showing heightened put buying and a put/call ratio of 1.02.

The broader market context added pressure. The Financial Stability Board’s chief, John Schindler, warned that the AI sector’s rapid growth resembled the dotcom bubble, raising concerns about a potential financial crisis. This rhetoric coincided with a $658 billion loss in U.S. Tech stocks in July 2026, as investors rotated capital toward Bitcoin and away from AI-related equities. Bitcoin’s price rose 1.41% to $64,370 amid the selloff, with some analysts suggesting a shift from AI stocks to cryptocurrency as a hedge against market volatility. Meanwhile, the Nasdaq-100 index hit an 11-week low, and the Fed’s upcoming decision loomed large, with markets anticipating rate hold decisions but remaining wary of macroeconomic uncertainty.

Micron’s struggles underscored the sector’s vulnerability to cyclical shifts and geopolitical dynamics. While the company’s CEO, Sanjay Mehrotra, framed memory as a “defining strategic asset in the AI era,” investors grappled with the risk of a 2023-style revenue collapse, when gross margins turned negative. The path to recovery depends on execution—specifically, whether Micron can fulfill 50% to two-thirds of key customer demand and avoid a hyperscaler capex reset. For now, the market remains divided: some see a structural shift toward AI-driven demand, while others fear a repeat of past memory cycles, leaving Micron and its peers caught in a tug-of-war between optimism and caution.
