On July 28, Roundhill Memory ETF declined 5.19% overnight, trading at $49.66/share, with turnover of $52.96 million.

The decline was driven by a deepening global memory chip selloff. South Korea's KOSPI index plunged over 6%, with SK Hynix falling more than 9% and Samsung Electronics dropping over 7%. SK Hynix alone saw approximately $470 billion in market value evaporation, as cracks emerged in the memory chip boom narrative.

Notably, the selloff came despite weekend news that SK Group and Samsung Electronics signed chip cooperation partnerships worth approximately $9,500 billion with major U.S. tech companies, including supply agreements with Anthropic. While these announcements briefly lifted memory stocks in pre-market trading on July 27, gains failed to hold through the regular session. Morgan Stanley recently warned that the AI-driven semiconductor memory frenzy is approaching an inflection point, with memory contract prices expected to peak in Q4. The broader semiconductor sector has fallen over 43% from its early July highs, with the memory chip crash widely viewed as the primary catalyst for the current market turbulence.
