TradFi Pre-market Focus: Micron (MU) Breaks $1000 Barrier, Goldman Sachs Raises Profit Forecasts for Hynix and Samsung, AI Super Cycle Continues

June 1st – Over the weekend, the U.S. stock market has been abuzz, particularly around tech stocks tied to AI-related semiconductors and storage (memory) sectors. SK Hynix, Micron Technology (MU), and Samsung Electronics joined the trillion-dollar market cap club last Tuesday through Wednesday, emerging as the new front-runners in the AI memory chip space. This milestone is directly fueled by surging demand for high-bandwidth memory (HBM), DRAM, and NAND flash memory spurred by exponential growth in AI computing power. Global memory chip shortages are intensifying as AI data center construction accelerates, and Micron confirmed its entire 2026 HBM production capacity is already sold out—a development that has significantly boosted its pricing power. On Trade.xyz, after modest gains, both MU and SK Hynix crossed the $1,000 threshold this morning, logging a 3.27% increase over the past 24 hours. SK Hynix showed upward momentum over the weekend without a pullback; following a minor dip at the Korean stock market open, it rebounded to a 0.68% gain in the same period. Investment banks like Goldman Sachs have simultaneously raised earnings forecasts for SK Hynix and Samsung, projecting robust profit growth from 2026 to 2028. The catalyst is AI demand—covering training, inference, and smart device systems—far outstripping supply. The broader storage sector is heating up, with products like the Roundhill Memory ETF (focused on DRAM), which holds heavy positions in Micron, SK Hynix, and Samsung, being dubbed by investors as a "golden ticket" to AI infrastructure. That said, market watchers flag the traditional boom-bust cycle risk inherent to the memory industry, with some analysts cautioning the current rally may have peaked. In overnight trading, U.S. stock futures notched modest gains driven by upbeat AI sentiment: Nasdaq 100 futures rose roughly 0.45%, S&P 500 futures added 0.23%–0.24%, and Dow futures edged up about 0.1%, signaling tech stocks are set to extend their strength at Monday’s opening bell. On social media, Micron’s $1,000 milestone sparked widespread discussion, turning the storage leader into a capital focus—with related Korean stock targets hitting new highs in tandem. Overall, the AI supercycle remains intact, and the semiconductor sector, especially AI memory and storage, is drawing short-term capital flows. Still, investors should monitor macro data like the upcoming jobs report and potential pullback risks.
