Roundhill Memory ETF (DRAM) plummeted 5.03% during regular trading, reflecting a sharp downturn for the memory-focused investment vehicle.

The decline was driven by a broad sell-off in U.S.-listed storage concept stocks at the market open. Core ETF holding SK Hynix fell over 8%, while SanDisk dropped over 4%, and both Micron Technology and Western Digital each slid over 2%, collectively weighing heavily on the fund. Sentiment was further dampened by pressure on A-share storage chip names, with one major player hitting limit-down despite forecasting a massive year-over-year earnings increase, as investors focused on a concerning sequential decline in its second-quarter results.

The sharp reversal comes after the ETF rebounded over 6% in the prior session, highlighting intense short-term volatility and broader market concerns over peak cycle dynamics within the memory industry.
