On July 28, Roundhill Memory ETF declined 8.13% in regular trading, trading at $47.65/share, with turnover of $584 million. The ETF, which tracks global memory chip companies, reflected intense selling pressure across the sector.

On the news front, the global memory chip sector experienced a severe rout. South Korea's KOSPI index plunged 10.84%, with industry leader SK Hynix falling over 13% and Samsung Electronics dropping 13.39% — its largest single-day decline in 18 years. SK Hynix has seen approximately $470 billion in market value evaporate since its June peak, with its US-listed ADR falling below its IPO price less than a month after listing. Meanwhile, China's CXMT surged 466% on its debut, intensifying concerns over rising competition in the DRAM market. Morgan Stanley warned that the AI-driven memory boom is approaching an inflection point, with contract prices expected to peak in Q4. Pictet Hong Kong has reduced its SK Hynix holdings in recent weeks, reflecting widening institutional disagreement on valuations and deteriorating market sentiment.
