In terms of news, Micron Technology's stock surged over 19% in a single day, marking the largest single-day increase since 2011, becoming the second company among the three major storage giants to reach a market capitalization of $1 trillion, following Samsung Electronics. UBS significantly raised Micron's target price from $535 to $1625, the highest level on Wall Street, with the core logic not being HBM, but rather the first occurrence of long-term agreements (LTA) with partially fixed pricing in the memory industry. This model is expected to significantly smooth out profit fluctuations, weaken cyclical attributes, and shift the market from "cyclical stock valuation" to "growth stock valuation." Coupled with the simultaneous rise in HBM volume and price, and the prolonged supply-demand tension cycle, UBS believes Micron is undergoing a structural revaluation, with its market capitalization potentially reaching $1.8 trillion The target price of $1,600 not only highlights the core position of storage chips in AI infrastructure but also reflects a broader shift in the AI investment landscape: after initially flocking to invest in graphics processing unit manufacturers, investors are now seeking companies that can benefit from the massive spending plans of tech giants. Morgan Stanley recently pointed out in a research report that by 2030, the global semiconductor industry market size could reach $1.5 trillion, with AI-related semiconductor products contributing a significant share. The capital expenditures of major cloud service providers remain strong. Morgan Stanley's cloud capital expenditure tracker estimates that by 2026, cloud capital expenditures will approach $811 billion.
