Amplify has launched the first U.S. exchange-traded funds based on South Korea’s concentrated “Top 10” strategy, investing in 10 companies within each sector. The four funds cover quantum computing, space, robotics and Asian memory semiconductors, with Samsung Asset Management serving as sub-adviser. The Asia Memory ETF tracks the Akros Asia Memory Semiconductor Top 10 Index, which spans the region’s memory-chip supply chain and gives maximum index weights of 22.5% each to Samsung Electronics and SK Hynix. The launch is being viewed as a reverse export of South Korea’s ETF investment culture into the traditionally more broadly diversified U.S. market.
