micron technology Stocks caught fire this week amid a global memory chip shortage, with momentum pushing stocks higher as enthusiasm across the semiconductor sector grew.
Shares rose more than 15% on Friday, closing at $746.81. The company’s stock is up nearly 38% in the week and 84% in the past month.
Micron had its best week since December 2008, when it traded below $5 a share in the wake of the Great Recession. The company’s market capitalization currently exceeds $840 billion, according to LSEG.

Micron is not alone among chipmakers. shares of AMD Shares rose 26% for the week and hit a new 52-week high on Friday, giving the company a market capitalization of more than $740 billion.
intel The CPU maker’s comeback has been widely touted, with shares up 25% for the week and more than doubling in the last month.
Total capital investment from hyperscalers could exceed $1 trillion by the end of next year, according to Bank of America and Evercore, and demand for memory chips has emerged as a feature of this stage of AI construction.
So far, graphics processing units (GPUs) have been the hardware focus for building AI, but memory, storage, and CPUs are increasingly in the spotlight.
Amid the memory chip shortage, memory makers’ prices and profit margins are expanding, while hyperscalers are bemoaning rising costs for end-user products and services.
DRAM and NAND are the two most sought-after types of memory. DRAM is fast and unwieldy, while flash-based NAND is slightly slower and more reliable. Both are essential for AI processing.
According to multiple stock research reports, Micron, Samsung, and SK Hynix together produce more than 90% of the world’s DRAM.
Like Micron, Korean memory chip makers are also in trouble. This week, Samsung joined the $1 trillion valuation club, along with: apple, alphabet and microsoft.
SK Hynix is fielding a number of offers from global tech companies that want to invest in new production lines dedicated to memory to increase production, Reuters reported on Friday.
One of the proposals was an equipment financing deal related to ultraviolet lithography equipment from one of the company’s customers, the news agency reported.
“MU remains well-positioned across the memory landscape with cutting-edge DRAM nodes contributing to year-over-year cost savings, while we expect NAND to improve cost and increase wafer capacity due to increased layer count,” Mizuho analyst Vijay Rakesh said in a research note this week.
Researchers say Micron has captured a larger share of overall retail transactions in the past few months. Net buying reached its highest level in two years in mid-April, according to Vanda Research.
Viraj Patel, Banda’s strategist, said in comments to CNBC on Friday that this result comes despite overall stock buying by retail investors in recent months being somewhat softer than in previous years. “So Micron definitely has a much larger share of retail flow and attention,” he added.
