On July 16, Roundhill Memory ETF declined 5.05% in pre-market trading, at $54.5/share, with turnover of approximately $19 million.

The decline was driven by a broad global memory chip selloff spanning multiple markets. Overnight, U.S. memory stocks plunged — Micron and Western Digital fell over 8%, SanDisk dropped more than 12%, and SK Hynix ADR slid nearly 10%. The rout deepened when Korean markets opened, with the KOSPI index plunging nearly 7% and triggering a circuit breaker; SK Hynix fell over 11% and Samsung Electronics dropped over 8%.

Adding to the pressure, Korean prosecutors raided the Korean offices of Montage Technology, Renesas Electronics, and Rambus on suspicion of semiconductor component price collusion, further dampening sector sentiment. Separately, concerns over AI investment sustainability and a downward revision to Q3 DRAM price-hike expectations intensified selling across the memory supply chain globally.
