Micron Technology shares experienced a historic week, surging nearly 38% and extending its monthly gains to 84%, driven by a global shortage of memory chips. This incredible rally, Micron’s best since 2008, has propelled its market capitalization above $840 billion.
The demand for critical components like DRAM, NAND, and CPUs is intensifying as the artificial intelligence boom shifts focus beyond GPUs, fueling an epic run for semiconductor companies including AMD, Intel, and global giants like Samsung and SK Hynix.
Micron Technology (MU) shares ignited this week, propelled by a global shortage in memory chips and a surging wave of enthusiasm sweeping across the entire semiconductor sector. The stock closed Friday at an impressive $746.81, marking a more than 15% jump for the day. Over the past week, Micron's shares rocketed nearly 38%, extending its monumental gains to approximately 84% in just the last month.
This performance represents Micron's strongest weekly showing since December 2008, a period when the company's shares were trading below $5 in the wake of the Great Recession. Today, buoyed by unprecedented demand, Micron’s market capitalization stands robustly above $840 billion, according to LSEG.
Micron is far from alone in this exhilarating rally. Other chipmaking giants are also experiencing historic gains. Shares of Advanced Micro Devices (AMD) climbed 26% on the week, hitting a new 52-week high and pushing its market cap past $740 billion. Even Intel (INTC), long seen as playing catch-up, surged 25% for the week and has more than doubled in value over the past month, signaling a remarkable comeback for the CPU maker.
The current phase of the artificial intelligence buildout is increasingly defined by the soaring demand for memory chips. Industry analysts from Bank of America and Evercore project that total capital expenditures from hyperscalers could exceed $1 trillion by the end of next year, further solidifying the critical role of these components.
While graphics processing units (GPUs) have historically dominated the hardware narrative of AI development, the spotlight is now rapidly expanding to include memory, storage, and central processing units (CPUs). This shift underscores the comprehensive hardware requirements for advanced AI systems.
Amid this burgeoning demand, a significant shortage of memory chips has emerged, leading to widening prices and improved margins for memory manufacturers. Conversely, hyperscalers are reportedly lamenting the escalating costs for their end-user products and services, highlighting the tight supply-demand dynamics.
Key memory types driving this surge are DRAM (Dynamic Random-Access Memory) and NAND (flash-based memory). DRAM, known for its speed and sensitivity, and NAND, prized for its reliability, are both indispensable for robust AI processing. A mere three companies—Micron, Samsung, and SK Hynix—collectively produce over 90% of the world's DRAM, according to various equity research reports.
South Korean memory chip makers are mirroring Micron's success. Samsung Electronics joined the exclusive trillion-dollar valuation club this week, placing it alongside tech titans like Apple (AAPL), Alphabet (GOOGL), and Microsoft (MSFT). Meanwhile, SK Hynix is reportedly inundated with offers from global tech firms eager to invest in new, memory-dedicated production lines to boost output, Reuters reported.
Mizuho analyst Vijay Rakesh observed, "MU remains well positioned across the memory landscape with leading edge DRAM nodes helping drive cost-downs year-over-year, while NAND sees increasing layer counts drive better costs and increase wafer capacity."
Beyond institutional interest, Micron has also been capturing a growing share of retail trading activity. Net buying reached its highest level in two years in mid-April, as per Vanda Research. "So arguably, Micron is commanding a much bigger share of retail flow and attention," noted Viraj Patel, a strategist with Vanda, underscoring the broad-based excitement surrounding the company's prospects.
