On July 2, Roundhill Memory ETF declined 5.03% overnight, trading at $62.54/share, with turnover of $173 million.

On the news front, Meta announced plans to enter cloud infrastructure services by selling excess AI computing power to external clients, triggering widespread fears of a computing power oversupply inflection point. The move was interpreted as a signal that Big Tech capital expenditure on AI infrastructure may have peaked, sending storage and semiconductor stocks sharply lower. Micron Technology fell 10.57%, SanDisk dropped 10.62%, and the Philadelphia Semiconductor Index declined 6.27%. In Korea, the KOSPI triggered a circuit breaker mechanism, with SK Hynix falling over 8% and Samsung Electronics dropping over 7%.

Compounding the pressure, Samsung, SK Hynix, and Micron face a class-action lawsuit in U.S. federal court alleging coordinated DRAM price manipulation since 2022, with plaintiffs seeking treble damages. All three companies have prior price-fixing convictions, intensifying investor concern. These three stocks constitute over 74% of the ETF's weighting, directly dragging down its net asset value.
