The Roundhill Memory ETF is probably the best way to get exposure to the AI memory and HBM supercycle. It holds the three companies that control the HBM market, Samsung at 25%, SK hynix at 25% and Micron at 24%. Its 0.75% fee is not cheap but not extreme. SK Square is also a way to get SK hynix exposure at a discount. x.com x.com x.comÂ
The Roundhill Memory ETF is a genuinely great way to get memory exposure, especially without access to foreign stocks. It concentrates on the three leaders, Micron at 24.6%, Samsung at 24.1% and SK Hynix at 23.1%, plus SanDisk, Kioxia, Western Digital, Nanya and Winbond. x.comÂ
Memory stocks are one of the easiest buys right now because supply has no visible path to catch up with demand. Micron CEO Sanjay Mehrotra said the company currently has no line of sight on when memory supply will catch up with increasing demand. x.comÂ
The Roundhill Memory ETF looks vulnerable because its late launch fits the pattern of Wall Street selling hot themes to the public shortly before they top. DRAM was a monster trade of 2026 in April and May, led by Sandisk and Micron. It topped two months after debut and is rolling into Stage 4 against its 10-week EMA; the similarly late-launched FOTO photonics ETF topped in just two weeks. x.comÂ
Rising memory contract prices strengthen the case for memory stocks still far below their highs. JPMorgan forecasts Q4 DRAM prices up 13% and NAND up 18%; Micron is 28% below its 52-week high, Seagate 44%, Sandisk 47% and Western Digital 55%. x.comÂ
SK hynix's five-year agreements with 14 major customers cover more than half its 2027-28 capacity, giving its memory earnings unusually long visibility. DRAM prices rose 28% and NAND 25% in the quarter, while operating profit reached 62.8 billion against 58.5 billion expected; Q4 DRAM shipments are guided up 25% from Q3. Those commitments support the view that demand is not peaking yet. Overweight, $400 target. x.comÂ
The memory ETF is not worth buying yet, because it is essentially just the KOSPI plus Micron and more forced selling is likely in Korea. x.comÂ
Micron, Samsung Electronics and SK hynix look very cheap if their long-term agreements do not impose overly conservative price ceilings. Greater clarity on those pricing terms could send memory stocks up 30% in a single day. x.comÂ
More memory CapEx may yield proportionally fewer bits as HBM consumes more wafer capacity, supporting SK hynix and Samsung's pricing. Both reported double-digit quarterly DRAM and NAND price gains; Samsung targets 60-70% of mid- to long-term capacity under LTAs. SK hynix has the stronger execution record, but Samsung could benefit enormously from conventional memory without winning HBM4. If trends persist, normalized margins could rise, though memory remains cyclical. x.comÂ
SK hynix's new direct US listing is a small disadvantage for the Roundhill Memory ETF, which investors had bought partly to own SK hynix indirectly. Owning memory companies directly is preferable to the ETF. x.comÂ
SK hynix's strong pricing and secured capacity could push memory stocks higher. Per Wall St Engine, its Q3 DRAM ASP rose by a high-20s percentage quarter over quarter, while long-term agreements cover more than half of its 2027-28 capacity. Those figures support the memory upcycle. x.comÂ
