AI megatrend storms back! Premia China STAR50 ETF (03151.HK) surges over 3.5%, with Montage Technology spearheading gains of more than 10%.

New Space News – 21 Jan: The AI theme roared back, with CPU, memory-chip and advanced-packaging concepts leading the charge. Montage Technology jumped more than than 10%.Premia China STAR50 ETF(03151.HK) climbed over 3.5% in early trade, approaching its October peak; the counter has drawn more than HK$120 million of net inflows over the past 60 sessions.

HKEX data show the ETF tracks the SSE Sci-Tech 50 Index, which comprises the 50 largest and most liquid stocks on the STAR Market. The gauge is dominated by “hard-tech” leaders: semiconductors account for more than 65%, and together with medical devices, software development and PV equipment the weighting nears 80%. Semiconductor chips alone command roughly 31%, followed by computer applications, special-purpose equipment, chemicals and bio-medicine; the top three sectors exceed 86% in aggregate, aligning with Beijing’s “tech-powered national rejuvenation” strategy.

Overnight, U.S. memory names bucked the trend and surged. Micron rose 5% to a fresh record, with at least two brokers lifting their target prices; SanDisk leapt 8% and also hit an all-time high.

KeyBanc notes Intel and AMD have already sold the bulk of their 2026 server-CPU capacity and both plan to raise prices by 10-15% in Q1. Street watchers argue the hike is driven by two factors: on the demand side, the expanding scale of AI inference is making CPUs a key bottleneck; on the supply side, advanced-process and advanced-packaging capacity is expanding only gradually, while GPU and other chips are crowding out available wafers, further strengthening CPU vendors’ pricing power.
