South Korean asset managers are broadening semiconductor exchange-traded funds beyond GPUs and high-bandwidth memory (HBM) as artificial intelligence services increase demand for data storage. KB Asset Management said on the 1st that it will launch the RISE Global AI NAND Memory Semiconductor ETF, described as South Korea's first fund to invest across the global NAND flash memory value chain. The fund will allocate 70% to four leading companies that manufacture NAND flash or provide NAND-based storage solutions, with the remaining 30% invested across storage infrastructure. Its largest holdings include Samsung Electronics at 19.9%, SK hynix at 18.8%, SanDisk at 16.4%, Kioxia at 12.3% and Micron Technology at 11.4%. The strategy reflects expectations that AI investment will expand from training-focused computing into inference, storage and data movement, while CPUs and related infrastructure gain importance. Existing market analysis has also pointed to rising demand for standard DRAM, NAND flash, solid-state drives and storage networks, alongside possible memory-bandwidth bottlenecks.
