Roundhill Memory ETF bets heavily on Micron amid AI chip demand
The Roundhill Memory ETF, launched in April, has put 26% of its assets into Micron Technology and said returns are up 80% in four months.
Roundhill Investments launched the Roundhill Memory ETF (NYSEMKT: DRAM) in April, positioning the fund to invest exclusively in memory-focused stocks used across AI hardware, including data centers and smartphones, according to Yahoo Finance.
The ETF has already generated an 80% return in just four months, and Micron Technology accounts for more than one-quarter of the fund's assets. Yahoo Finance said portfolio data is accurate as of Aug. 10, 2026, and the ETF holds 24 stocks overall.
Yahoo Finance also tied the fund's momentum to demand for high bandwidth memory, or HBM, as data center operators buy at a rapid pace to power AI workloads. The outlet said a broader global memory shortage has emerged, with suppliers reducing capacity in some segments to prioritize HBM.
As a result, Yahoo Finance reported that Micron, Samsung Electronics, and SK Hynix have been able to dictate prices and are seeing sharp gains, with Micron shares up more than 600% over the past 12 months. The outlet added that the top three holdings represent 70.9% of the portfolio value, and Micron and peers are racing to ramp production of new HBM4 chips for AI use cases.
