Micron Technology (MU) delivered its best weekly performance since 2008, surging nearly 38% and pushing its market cap above $840 billion, fueled by a global memory chip shortage and intense AI-driven demand. This rally is part of a broader semiconductor surge, with AMD and Intel also seeing significant gains as memory, storage, and CPUs become critical hardware for the evolving artificial intelligence buildout.
Memory chip giant Micron Technology (MU) has ignited the semiconductor sector, posting its most explosive weekly gains since the 2008 Great Recession. Amid a global shortage of essential memory chips and rampant enthusiasm for artificial intelligence, Micron's stock price soared by nearly 38% this week, closing Friday at an impressive $746.81. This surge caps off a remarkable month for the company, with shares rocketing almost 84% and pushing its market capitalization beyond $840 billion, according to LSEG data.
The rally extends beyond Micron, reflecting a broader parabolic surge across chipmakers. Advanced Micro Devices (AMD) shares climbed 26% this week, reaching a new 52-week high and boosting its market cap past $740 billion. Even Intel (INTC), long seen as a struggling veteran, staged a significant comeback, jumping 25% this week and more than doubling its value over the past month.
This escalating demand for memory chips and CPUs is now defining the next phase of the artificial intelligence boom. Industry analysts from Bank of America and Evercore project that capital expenditures from hyperscalers could exceed an astounding $1 trillion by the end of next year. While Graphics Processing Units (GPUs) initially hogged the AI hardware spotlight, memory, storage, and Central Processing Units (CPUs) are increasingly becoming central to the conversation.
The critical shortage of memory chips is leading to widening prices and margins for manufacturers, much to the chagrin of hyperscalers facing increased costs for their end-user services. The two primary types of memory driving this demand are DRAM (faster, more intricate) and NAND (slower, more reliable flash storage), both indispensable for AI processing.
Micron, alongside South Korean powerhouses Samsung and SK Hynix, collectively produces over 90% of the world's DRAM. These Asian chipmakers are also experiencing unprecedented growth; Samsung recently joined the exclusive trillion-dollar valuation club, aligning with tech giants like Apple, Alphabet, and Microsoft. SK Hynix, in particular, is reportedly inundated with offers from global tech firms eager to invest in new, memory-dedicated production lines to ramp up output, including equipment financing deals for advanced ultraviolet lithography machines, as reported by Reuters.
Mizuho analyst Vijay Rakesh noted in a recent report, "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."
Retail investors are also flocking to Micron. Vanda Research indicates that net buying for Micron reached a two-year high in mid-April. Despite a generally softer retail stock-buying trend over recent months, Micron is "commanding a much bigger share of retail flow and attention," according to Viraj Patel, a strategist at Vanda.
