On July 2, Roundhill Memory ETF declined 5.62% in pre-market trading, trading at $62.43/share, with turnover of $33.77 million.

On the news front, Meta reportedly plans to enter the cloud infrastructure market by selling excess AI computing resources externally, triggering widespread fears of computing power oversupply. This catalyzed a broad sell-off across semiconductor and memory stocks overnight, with the Philadelphia Semiconductor Index plunging 6.27%, Micron Technology falling 10.57%, and SanDisk dropping 10.62%. Korean markets opened with circuit breakers triggered, as Samsung Electronics fell over 7% and SK Hynix declined over 8%.

Simultaneously, Samsung, SK Hynix, and Micron face a class-action antitrust lawsuit in California federal court alleging coordinated DRAM price manipulation. Plaintiffs are seeking treble damages, and all three companies have prior price-fixing convictions. The ETF's top three holdings — Samsung, Micron, and SK Hynix — collectively represent over 74% of portfolio weight, making it directly exposed to the sector-wide systemic sell-off.
