Micron ($MU) shares surged 16% to $875, a new all-time high. UBS has set a target price of $1625—implying an 87% upside. This isn't just ordinary analyst hype. The underlying logic is that HBM (High Bandwidth Memory) is becoming a real bottleneck for AI infrastructure. Each H100/B200 chip requires a large amount of HBM3E, and only three companies globally can mass-produce it—SK Hynix, Samsung, and Micron. Micron has the lowest market capitalization among them, but is catching up technologically the fastest. This target price essentially bets that the AI computing power arms race will drive memory demand to a whole new level. However, whether $1625 will materialize depends on two variables: the shipping pace of NVIDIA's next-generation GPUs and the speed at which Micron's HBM yield rate ramps up. No one can give a definitive answer to either of these at present. What do you think—should we chase the rally or wait for a pullback?
