On July 28, Roundhill Memory ETF fell 7.06% in pre-market trading, trading at $48.93/share, with turnover of $12.7463 million. The sharp decline reflected a sweeping global selloff in the memory chip sector driven by multiple converging headwinds.

On the news front, South Korea's KOSPI index plunged over 11%, with SK Hynix falling over 13% and Samsung Electronics dropping 13.4% — its worst single-day decline since October 2008. The selloff was fueled by China's DRAM leader CXMT surging 466% on its listing day, intensifying fears of heightened industry competition. SK Hynix's U.S. ADR broke below its IPO price less than a month after listing. Morgan Stanley warned that the AI-driven semiconductor memory boom is nearing an inflection point, with memory contract prices expected to peak in Q4. Swiss Pictet Hong Kong also reportedly reduced its SK Hynix holdings, reflecting growing institutional divergence on valuations. SK Hynix has seen approximately $4,700 billion in market value erased since its June high, as investors worry AI-themed trades have become overly crowded.
